In the rapidly growing, multi-billion-dollar animal health industry, one company has carved out a unique and incredibly profitable niche for itself. While companies like Zoetis are leaders in animal pharmaceuticals, IDEXX Laboratories is the undisputed king of veterinary diagnostics. For decades, this high-tech innovator has been the driving force behind the modernization of the veterinary clinic, providing the essential diagnostic instruments and tests that allow veterinarians to practice a higher standard of medicine. IDEXX's success is built on a brilliant and highly durable "razor-and-blade" business model, where the placement of its sophisticated in-clinic analyzers creates a long-term, recurring revenue stream from the single-use tests and consumables required for every diagnosis. This has turned IDEXX into a high-growth, high-margin machine that has delivered phenomenal returns for long-term investors. Fueled by the unstoppable trend of pet humanization, the company is poised for a long runway of continued growth. But with a premium valuation and growing competition, is IDEXX still a compelling buy for new investors? This in-depth analysis will dissect the investment case for the premier leader in veterinary diagnostics, from its innovative history to the powerful growth drivers that will shape its future. Content⁉️ 1️⃣ A Legacy of Diagnostic Innovation 2️⃣ The Business Model: A Perfect "Razor-and-Blade" Fortress 3️⃣ Financials: A Profile of a Premier Growth Compounder 4️⃣ Fundamental Data 🔖 Key Takeaways A Legacy of Diagnostic Innovation IDEXX Laboratories was founded in 1983 with a focus on developing diagnostic tests for animal health, specifically for poultry and livestock. However, the company’s destiny was transformed in the early 1990s when it turned its attention to the nascent market of companion animal health. At the time, veterinary medicine was far less sophisticated than human medicine. Most diagnostic testing was sent out to external reference laboratories, a slow and inefficient process. The founders of IDEXX saw a massive opportunity to bring the power of rapid, accurate diagnostics directly into the veterinary clinic. This vision led to a series of groundbreaking innovations that have defined the modern veterinary practice: The SNAP Test Revolution:  In the 1990s, IDEXX launched its proprietary SNAP test platform. These simple, in-clinic test kits allowed veterinarians to test for common diseases like heartworm, Lyme disease, and feline leukemia in just minutes, using a single blood sample. This was a game-changer, enabling faster diagnoses and immediate treatment decisions. Building the In-Clinic Laboratory:  Building on the success of its SNAP tests, IDEXX pioneered the concept of the in-clinic diagnostic suite. It developed a family of sophisticated, easy-to-use analyzers that could perform a wide range of blood chemistry, hematology, and urinalysis tests right in the veterinary clinic. Creating a Connected Ecosystem:  IDEXX was one of the first companies to integrate its instruments with practice management software, creating a seamless digital ecosystem that automates workflows, captures charges, and allows for better data analysis and patient care. This history of relentless, customer-focused innovation has created a deep and durable competitive moat. IDEXX has become the trusted, indispensable partner for veterinary clinics around the world. The Business Model: A Perfect "Razor-and-Blade" Fortress IDEXX’s genius lies not just in its technology, but in its brilliantly executed business model. The company’s Companion Animal Group (CAG), which accounts for over 90% of its revenue, is a textbook example of the "razor-and-blade" strategy. 1. Instrument Placements (The "Razors"):  The first step is placing its suite of diagnostic instruments in veterinary clinics. This includes its flagship analyzers: *Catalyst:  For blood chemistry. *ProCyte:  For hematology (blood cell counts). *SediVue:  For urinalysis. IDEXX often places these instruments under long-term contracts with little to no upfront cost to the veterinarian, effectively removing the biggest barrier to adoption. With a massive global installed base of over 150,000 instruments, each new placement expands the company’s moat. 2. Consumables and Tests (The "Blades"):  This is the heart of the recurring revenue model and the company’s primary profit driver. Every instrument placed requires the use of proprietary, single-use slides, reagents, and other consumables for every test performed. This creates a highly predictable, high-margin, and growing stream of revenue that is directly tied to the volume of patient visits and diagnostic testing. This segment also includes the massive and highly profitable franchise of SNAP rapid assay tests, led by the flagship SNAP 4Dx Plus Test . 3. Software and Services (The Digital Ecosystem):  To lock in its customers, IDEXX provides a comprehensive suite of practice management software and data services. This deep integration makes it very difficult and costly for a veterinary practice to switch to a competitor, creating extremely high customer retention rates. This virtuous cycle is incredibly powerful: The more instruments IDEXX places, the larger its recurring revenue base becomes. This predictable cash flow then funds the R&D for the next generation of innovative instruments and tests, which further strengthens its market leadership. Other Business Segments While the companion animal business is the star of the show, IDEXX has two other stable, cash-generative businesses: Water Quality:  IDEXX is a global leader in providing microbiological tests to ensure the safety of drinking water. Livestock, Poultry, and Dairy:  This segment provides diagnostic tests and services to ensure the health and productivity of farm animals, playing a key role in global food safety. Financials: A Profile of a Premier Growth Compounder IDEXX's dominant market position and powerful business model have translated into one of the most consistent and impressive financial track records in the entire stock market. High, Consistent Revenue Growth:  For over a decade, IDEXX has been a model of consistency, reliably delivering double-digit annual revenue growth. This is driven by growth in the overall pet care market, increased diagnostic testing per patient, and consistent market share gains. Exceptional Profitability:  The company is incredibly profitable, with high and expanding operating margins. This is a direct result of its high-margin, recurring revenue from consumables and its scale advantages as the market leader. Capital Allocation for Growth:  IDEXX is a pure growth company and does not pay a dividend. It follows a disciplined capital allocation strategy, reinvesting its strong free cash flow back into the business to fund its industry-leading R&D budget and to make occasional, strategic "tuck-in" acquisitions. The company also consistently returns capital to shareholders through a robust share repurchase program. This combination of high growth, high margins, and disciplined capital allocation is why the market has consistently awarded IDEXX a premium valuation. Fundamental Data Go beyond the stock price with this deep dive into a company's core fundamentals. 🔖 Key Takeaways The decision to invest in IDEXX Laboratories is a decision to buy a best-in-class, high-quality growth company with a deep competitive moat and a long runway for continued expansion. It is a pure-play on the enduring trend of pets as family members. For the Long-Term Growth Investor:  IDEXX is a quintessential core holding. You are investing in a company that is the undisputed leader in its field, with a brilliant business model and a clear path to growing at a double-digit pace for the foreseeable future. For this type of investor, the premium valuation is the price to be paid for a company with such a dominant position and a consistent track record of flawless execution. For the Value or Income Investor:  This is not the right stock. The sky-high valuation is the antithesis of a value-investing strategy, and the lack of a dividend makes it a non-starter for income seekers. IDEXX Laboratories has built one of the most impressive and durable business models in the entire healthcare sector. By becoming the essential technology partner for veterinary clinics, the company has created a powerful ecosystem that is incredibly difficult to disrupt. While its premium valuation requires a long-term perspective and a tolerance for volatility, IDEXX’s track record of innovation and its clear runway for future growth make it one of the highest-quality growth compounders on the market today.

Eli Lilly and Co. is redefining its approach to the pharmaceutical market, establishing a bold direct-to-consumer strategy for its innovative GLP-1 drugs in key markets such as China and the United States.  This strategic move positions the company to capitalize on the growing demand for obesity and diabetes treatments. In China, Eli Lilly has forged a strategic partnership with JD Health International Inc. , a prominent Chinese online healthcare platform, to market its obesity and diabetes drugs, including Mounjaro, through direct-to-consumer channels. This collaboration offers a comprehensive "one-stop service" that includes consultations, prescriptions, home drug delivery, and subsequent follow-ups. It will even facilitate access to the company's alopecia treatments. This step is a response to the flourishing Chinese GLP-1 drug market, projected to reach between $5.6 billion and $11.4 billion annually, and is driven by China's state medical insurance policy which does not cover weight loss drugs, thus incentivizing the prioritization of retail and online channels. Lilly follows in the footsteps of its rival, Novo Nordisk, which already established similar deals with JD Health and other online platforms such as Tencent Health and Alibaba Health. Competition is intensifying with the entry of Chinese pharmaceutical companies like Innovent Biologics, which launched its weight loss drug mazdutide through online channels shortly after its approval. Simultaneously in the United States, Eli Lilly has expanded access to its lower-cost drug Zepbound (tirzepatide) , collaborating with telehealth providers such as Teladoc Health and LifeMD. Through Eli Lilly's self-pay pharmacy, GiftHealth, patients enrolled in virtual weight management programs can now access Zepbound at a reduced out-of-pocket cost, of $349 per month for a 2.5 mg vial, or $499 for 5 mg, 7.5 mg, and 10 mg doses. These virtual weight management programs, which already have thousands of patients at LifeMD (75,000) and millions at Teladoc (1 million enrolled in chronic condition management programs), offer remote monitoring, access to dietitians and health coaches. This integration aims to reduce barriers to high-quality care and FDA-approved treatments, while helping members afford transformative treatments and avoiding the potential risks of compounded medications. The company had already launched its own direct-to-consumer telehealth offering, LillyDirect, in January 2024, and had previously partnered with the telehealth platform Ro. This dual strategy underscores a broader transformation of the pharmaceutical industry towards digital healthcare delivery models. Eli Lilly is positioned to meet the growing demand for GLP-1 therapies , navigating the unique regulatory and market dynamics of each region. 🔖 Sources Eli Lilly Partners With China Tech Giant for Obesity Drug Sales Eli Lilly Partners with JD Health for Direct-to-Consumer GLP-1 Drug Sales in China Eli Lilly expands telehealth access to low-cost Zepbound with Teladoc Health, LifeMD tie-ups

Artificial intelligence (AI) is marking a before and after in medicinal chemistry, transforming everything from the creation of new treatments to the identification of illicit substances. Recent research from universities like Uppsala and British Columbia reveals how AI is accelerating critical processes and saving lives . In drug development, AI is proving powerful in predicting the three-dimensional structures of key receptors , a traditionally lengthy process. Researchers at Uppsala University used AI to model the TAAR1 receptor, a promising target for mental health disorders such as schizophrenia and depression . After predicting its structure, they found activating molecules, one of which showed promising effects in animal experiments . The accuracy of the AI models has been "astonishing," surpassing traditional methods. AI is also at the forefront of the fight against designer drugs , substances that evade detection and pose serious risks. Teams led by Jason Liang have created DAMD (Drugs of Abuse Metabolite Database) with nearly 20,000 predicted chemical structures  of metabolites, addressing the challenge of identifying new substances. In parallel, UBC researchers, including Dr. Michael Skinnider, trained a neural network that predicts the next designer drugs before they even hit the market , with over 90% accuracy. This reduces identification time from months to days , giving a crucial advantage to law enforcement agencies. "The accuracy of the structures generated with AI was astonishing—I couldn't believe it," stated Jens Carlsson, leader of the Uppsala study. For his part, Dr. Skinnider of UBC compared his model to "Minority Report" for being able to "predict what designer drugs are likely to emerge on the market". These AI applications not only accelerate the discovery and validation of new drugs  but also improve surveillance and medical response  to dangerous substances. DAMD could someday be a vital public tool, and the UBC model is already being used by international agencies. AI is opening a "huge opportunity" to shine a light on an "unknown chemical world". 🔖 Sources AI predicts designer drug structures for improved detection UBC researchers train computers to predict the next designer drugs AI predicts 3D structures of receptors for drug development

Science is making significant strides in the fight against obesity, with two promising breakthroughs opening the door to the next generation of treatments. Recent research highlights a new understanding of amylin receptors  and the development of edible fat-trapping microbeads , offering both pharmacological and non-pharmacological approaches to weight management. A University of Oklahoma study, published in Science Signaling , has revealed a new and crucial understanding  of how amylin receptors react upon activation. Amylin is a hormone secreted by the pancreas that controls appetite and blood sugar. Augen Pioszak, Ph.D., the paper's senior author, emphasizes that these receptors are very complicated  and possess unique properties. His laboratory's research has discovered how the three amylin receptors share a core component but have differing accessory subunits , giving them a key distinction. Furthermore, drugs can affect these receptors by pulling them together or pushing them apart, an important mechanism for drug development. This new methodology allows researchers to understand exactly what developing drugs do at each of the three amylin receptors, which is crucial for creating medications that effectively control appetite with fewer side effects. Amylin receptors belong to the same family as GLP-1 receptors, already targeted by pioneering drugs like semaglutide (Ozempic and Wegovy). In a completely different approach, researchers at Sichuan University have developed edible microbeads  that promise weight loss without drugs or surgery. These small spheres, made from green tea polyphenols, vitamin E, and a seaweed polymer , are designed to bind to fats in the gastrointestinal tract. Preliminary results in rats on high-fat diets have been striking : Rats that consumed the microbeads lost 17% of their total body weight . They showed reduced adipose tissue and less liver damage . They excreted more fat in their feces without apparent ill effects  on their health. Unlike medications such as orlistat, which can cause gastrointestinal side effects or liver and kidney damage, these microbeads did not present such problems in rats, offering a noninvasive and gentle method . Researchers envision that these nearly flavorless microbeads could be easily integrated into people's diets, perhaps as pearls in desserts or "bubble tea" type drinks. A human clinical trial has already begun with 26 participants at West China Hospital of Sichuan University, marking a significant step toward their potential clinical use. Both discoveries represent a promising future for obesity treatment, addressing a major public health concern linked to diseases like diabetes and heart conditions. 🔖 Sources Edible microbeads trap fat to support weight loss A new understanding of amylin receptors could pave way for next generation of weight loss drugs Fat-Trapping Microbeads Cut Obesity Without Drugs in Rats

Hepatic medicine is witnessing a significant transformation thanks to the identification of Chitinase-3-like protein 1 (CHI3L1)  as a crucial biomarker  for the diagnosis, monitoring, and treatment of various liver conditions. This protein, a member of the glycoside hydrolase family 18, is unique for its ability to bind to ligands and influence multiple pathophysiological processes, including cell proliferation, inflammation, fibrosis, and carcinogenesis, despite lacking enzymatic activity. Liver diseases, such as hepatitis-related fibrosis, non-alcoholic fatty liver disease (NAFLD), alcoholic liver disease (ALD), and hepatocellular carcinoma (HCC), represent considerable global health challenges. Early and accurate diagnosis is vital, but traditional methods like liver biopsy are invasive and not ideal for frequent monitoring. In this context, CHI3L1 emerges as a non-invasive and reliable alternative , especially for diagnosing and staging hepatic fibrosis. Its elevated levels correlate directly with the severity of fibrosis, demonstrating superior diagnostic efficacy  compared to conventional markers like hyaluronic acid (HA) and the FIB-4 index, particularly in patients with chronic hepatitis B (CHB) and chronic hepatitis C (CHC). Beyond its diagnostic capabilities, CHI3L1 plays a fundamental role in evaluating fibrosis progression and monitoring the efficacy of antiviral therapies . The protein's levels increase proportionally with the advancement of liver fibrosis, making it a practical tool for assessing treatment response. Furthermore, CHI3L1 has shown promise in distinguishing between simple steatosis and non-alcoholic steatohepatitis (NASH) , a crucial step for identifying patients at higher risk of progressing to cirrhosis or HCC. Combining CHI3L1 with other markers, such as alpha-fetoprotein (AFP) and platelet count, further enhances diagnostic accuracy, especially in detecting significant fibrosis and advanced stages of liver disease. One of the most promising applications of CHI3L1 is its potential to predict the prognosis of HCC . Studies indicate that elevated CHI3L1 levels are associated with poorer survival rates , particularly after curative resection. When combined with AFP, CHI3L1 significantly improves the diagnostic accuracy for HCC, offering clinicians a more reliable method for early detection and risk assessment. The growing body of evidence supports the use of CHI3L1 not only as a biomarker but also as a potential therapeutic target . As a key regulator of fibrosis and inflammation, targeting CHI3L1 could mitigate disease progression  and improve outcomes for patients with chronic liver diseases. Future research into the molecular mechanisms underlying CHI3L1's actions will deepen our understanding of liver pathology and pave the way for novel therapeutic strategies . The integration of CHI3L1 measurements into routine clinical practice could transform patient management, allowing for more precise risk stratification and personalized therapies. 🔖 Sources CHI3L1 emerges as a powerful biomarker for liver disease diagnosis and management Chitinase-3-like protein 1: a novel biomarker for liver disease diagnosis and management Chitinase-3-like Protein 1 Emerges as a Promising New Biomarker for Diagnosing and Managing Liver Disease

Akeso, Inc. ( 9926.HK ) is marking a significant milestone in the fight against lung cancer with its innovative PD-1/VEGF bispecific antibody, ivonescimab. The company has announced "statistically significant and clinically meaningful" results demonstrating an improvement in overall survival (OS)  in lung cancer patients, a key achievement that strengthens its position as a potential new global standard of care. Recently, Akeso reported that the first patient was dosed in its Phase III study (AK112-311/HARMONi-9), which evaluates ivonescimab as consolidation therapy for limited-stage small cell lung cancer (LS-SCLC) after definitive chemoradiotherapy. This is the eighth registrational Phase III clinical trial for ivonescimab in lung cancer, aiming to address an unmet clinical need in an aggressive cancer type with a poor prognosis. In previous studies on extensive-stage SCLC, ivonescimab had already demonstrated its ability to prolong progression-free survival (PFS). Furthermore, the Chinese company has revealed that ivonescimab has met its overall survival (OS) goal for the first time  in the final analysis of the Phase III HARMONi-A study. This China-only trial evaluated the drug in combination with chemotherapy in patients with EGFR-mutated, non-squamous non-small cell lung cancer (NSCLC) whose diseases had progressed after tyrosine kinase inhibitor therapies. The results not only reinforce ivonescimab's value in PFS but also highlight its ability to improve OS, a crucial endpoint in global oncology drug development. Previously, in April 2025, Akeso also announced "strongly positive" results from the Phase III clinical trial (AK112-306/HARMONi-6) for the first-line treatment of advanced squamous NSCLC. In this study, ivonescimab in combination with chemotherapy significantly outperformed tislelizumab plus chemotherapy in terms of PFS, in both PD-L1-positive and negative populations. These results position ivonescimab to improve upon and potentially replace the current standard of care for NSCLC treatment. With these results, ivonescimab redefines lung cancer treatment . These advancements consolidate Akeso's "IO 2.0" strategy, which aims to expand ivonescimab's therapeutic coverage across various lung cancer indications and treatment lines. Akeso's therapy is being positioned as a rival to key drugs like Merck's Keytruda, and its positive results increase expectations for the global HARMONi trial, which could replicate these benefits in Western populations and support FDA approval. 🔖 Sources Akeso says its closely watched drug improved patient survival in a lung cancer trial Akeso, Summit's PD-1xVEGF drug meets overall survival goal for the first time in a lung cancer trial Akeso Announces First Patient Dosed in Phase III Trial of Ivonescimab as Consolidation Therapy for Limited-Stage SCLC After Definitive Radiotherapy

Imagine being able to detect the risk of Alzheimer's disease years before the first symptoms appear, through a simple eye exam. This possibility is becoming a reality thanks to current research. Scientists are exploring the eye as a "window to the brain," as the retina, located at the back of the eye, shares structural and functional characteristics with the brain, containing nerves and blood vessels that come directly from it. Dr. Edgardo Rivera, Medical Director at Charter Research in Orlando, explains that the retina can provide valuable information not only about eye diseases but also about systemic conditions, including Alzheimer's. Researchers are studying subtle changes in how light scatters in the retina, as well as the thinning of retinal arteries, as potential early biomarkers for the disease. A new study by The Jackson Laboratory (JAX) has identified abnormal changes in the tiny blood vessels of the retina in mice with a common genetic mutation (MTHFR677C>T), associated with an increased risk of Alzheimer's. These changes include twisted, narrowed, and swollen vessels, and reduced vascular branching, which are similar to brain changes related to poor blood flow and cognitive decline. Furthermore, disruptions in protein patterns have been observed in both brain and retinal tissue, affecting cellular energy production, waste protein removal, and vascular support. Two innovative eye tests are being evaluated: RetiSpec:  Uses a special attachment on an existing eye exam camera. Artificial intelligence (AI) analyzes the reflected light in the images to detect patterns that could indicate early Alzheimer's. ViewMind:  Assesses eye movements in relation to cognitive tasks using a special headset with eye-tracking capabilities. A healthcare provider interprets how eye movements respond to visual exercises using proprietary software. These non-invasive tests promise to be quicker, simpler, and more affordable than traditional PET brain scans. Currently, the Bio-Hermes-002  study, supported by the Global Alzheimer's Platform (GAP) Foundation and facilitated by Charter Research in Orlando, is evaluating RetiSpec, ViewMind, blood biomarkers, and digital tests alongside traditional PET scans to predict Alzheimer's. Participants in this study can receive free brain MRIs and PET scans, blood tests, eye tests, and cognitive assessments, representing a significant benefit given the high cost of these tests. Dr. Alaina Reagan, a neuroscientist at JAX, emphasizes that collaboration with clinicians and dementia specialists aims to translate these findings into human application, suggesting that individuals with retinal vascular changes could be identified as high-risk decades before cognitive damage becomes noticeable. Participation in this research is crucial for developing better detection and treatment options for future generations. 🔖 Sources Routine eye exams may help detect Alzheimer’s years before symptoms appear Eye Exams May Offer Early Detection Pathway for Alzheimer’s Disease Could Eye Exams Detect Alzheimer’s?

A revolutionary study from the University of Auckland  has revealed that a single capsule of healthy gut bacteria  can provide significant and long-term metabolic benefits  in obese adolescents, even without substantial weight loss. Published in the prestigious journal Nature Communications , these findings suggest a promising future for the treatment of obesity and its complications. Eight years ago, 87 obese adolescents participated in a groundbreaking study to evaluate whether fecal microbiota transplantation (FMT) , which involves administering "good" gut bacteria from healthy donors in capsule form to individuals with a less healthy microbiome, could improve their health and weight. Four years after the initial intervention, a detailed follow-up study showed that adolescents who received the transplant had a reduced risk of developing metabolic changes  that typically lead to heart disease, stroke, and diabetes, compared to the group that received a placebo. Although the treatment group did not experience statistically significant weight loss, what was notable was that they did not gain weight , unlike the placebo group. In fact, the treated group was, on average, 11 kg lighter than the placebo group after four years, although this was not considered statistically significant. Professor Wayne Cutfield  of the University of Auckland’s Liggins Institute highlighted the dramatic impact on metabolic syndrome . This syndrome is defined as a cluster of five conditions (high blood pressure, high blood sugar, a large waist circumference, elevated triglycerides, and low HDL cholesterol) that increase the risk of death from heart disease or stroke by two times and the risk of type 2 diabetes by five times. More than one in three of the original teenage participants in the study had metabolic syndrome. A crucial finding of the follow-up study was that the healthy bacteria introduced were still present and thriving  in the participants' guts four years after the single transplant. This discovery challenges previous assumptions about the longevity of therapeutic microbiome alterations. Professor Justin O'Sullivan  noted that this "really makes us think about the timeframes over which we look for the impacts of microbiome-based treatments". This advance lays the groundwork for the development of next-generation probiotics  that could "program" the microbiome to reduce the risk of conditions before they manifest. The commercialization  of a custom-designed "super mix" of bacteria to prevent or moderate metabolic syndrome is the ultimate goal, and the Liggins Institute is already working on its production and trial. Adolescent obesity is a growing global public health problem, often extending into adulthood and increasing the risk of various metabolic diseases. Probiotics, defined as live microorganisms beneficial to host health, can influence obesity by regulating the balance of the gut microbiota, reducing chronic inflammation, and modulating lipid metabolism. While clinical evidence on probiotics in adolescents has shown mixed results and limitations in sample size and intervention duration in many clinical trials, the present study underscores the potential of microbiome-based interventions to generate a lasting impact on health. 🔖 Sources Healthy gut bacteria capsules show long-term benefits for obese teenagers The role of probiotics in adolescents’ obesity The good sh*t helping obese teens Research Reveals Major Health Benefits from Gut Microbiome Transplants

Medical science is constantly seeking less invasive methods to monitor health and detect chronic diseases. Recent studies have highlighted the potential of bodily fluids such as saliva and tears to replace, under certain conditions, traditional blood tests. This innovation could transform the way we diagnose and monitor conditions like diabetes and obesity. A pilot study, published in the journal Physiologia , investigated the feasibility of saliva and tears as alternatives for measuring vitamin D and glucose levels in patients with type 2 diabetes and healthy adults. The findings suggest a strong positive correlation between blood and tear glucose levels , indicating that tear sampling could be a potentially reliable and non-invasive alternative approach for monitoring glucose levels in diabetic patients. Regarding vitamin D, the study found a significant negative correlation between blood and salivary vitamin D levels in diabetic patients diagnosed for at least five years. Although saliva might reflect blood vitamin D levels under certain conditions, this capacity has not yet been established as a reliable matrix for vitamin D detection. The research also observed a tendency towards a non-significant negative correlation between vitamin D levels in blood and tears, with tears samples containing higher levels. It is important to note that previous findings in healthy volunteers showed a positive correlation, suggesting that health conditions may influence vitamin D levels in different biological samples. On the other hand, research from the University of British Columbia Okanagan, published in Applied Physiology, Nutrition, and Metabolism , reveals that saliva insulin tests offer a non-invasive method to effectively predict the risks of type 2 diabetes and obesity . Researchers observed that people with obesity had significantly higher insulin levels in their saliva at all evaluated time points, compared to individuals with normal weight or overweight, even when their blood glucose levels were similar. This study suggests that measuring saliva insulin could help identify hyperinsulinemia  (elevated insulin levels) much earlier than when blood glucose levels begin to rise, allowing for early interventions such as lifestyle changes. Hyperinsulinemia is a known predictor of various chronic conditions, including type 2 diabetes, hypertension, cardiovascular disease, stroke, and certain cancers. Furthermore, a strong relationship was found between obesity markers, such as waist circumference and body mass index (BMI), and higher levels of insulin in saliva, suggesting that waist circumference could be a more reliable indicator of hyperinsulinemia than age or overall body weight. Specific cut-off values for saliva insulin have been proposed to identify hyperinsulinemia. Both studies highlight the great potential of non-invasive tests for metabolic health monitoring , although they emphasize that these findings are preliminary and require large-scale studies to confirm the observed correlations and establish specific reference ranges for each biological fluid before clinical application. Factors such as protein content, pH, enzymatic activity, and viscosity of these matrices can affect analyte distribution and assay performance. 🔖 Sources Can saliva and tears replace blood tests for vitamin D and glucose?
