Metabolic Check-up : Longevity & Anti-Aging Blood Test with Nutritionist in Zurich & Geneva
Most chronic diseases do not arrive suddenly. They build quietly over years, driven by processes that are entirely measurable long before any symptom appears. Cardiovascular disease, metabolic syndrome, insulin resistance, cognitive decline. Each of these conditions has a biological signature that a targeted blood test can detect a decade or more before a diagnosis becomes inevitable.
The Metabolic Check-up is Labology's most advanced longevity and anti-aging blood test, combining cardiovascular risk markers, metabolic health indicators, and inflammation screening into a single powerful panel. Developed in partnership with Elodie Brocas, nutritionist in Zurich at The Good Life Specialist, this blood test is designed for those who want to stay ahead of their biology, not catch up with it. Your results come with a personalized nutrition and health plan built around your specific metabolic profile. Available in Zurich and Geneva, no prescription needed.
Understanding biological aging and why standard tests are not enough
A standard annual blood test checks your cholesterol, your blood sugar, and your kidney and liver function. These are useful. But they are designed to detect disease, not prevent it. They look for problems that have already developed, not for the early biological signals that predict problems years in advance.
ApoB, the HOMA index, high-sensitivity CRP, and morning cortisol are four markers that appear in the Metabolic Check-up and virtually nowhere in a standard Swiss health check. Each of them provides predictive information about long-term cardiovascular, metabolic, and cognitive health that the standard panel simply does not capture. Knowing these numbers at 35 or 45 is fundamentally different from finding out about them at 55, when intervention becomes correction rather than prevention.
What does our metabolic Check-up examine?
ApoB (Apolipoprotein B)
LDL cholesterol has been the standard measure of cardiovascular risk for decades. But the science has moved significantly beyond it. ApoB is now recognized by leading cardiologists and preventive medicine specialists as the single most accurate predictor of atherosclerosis and coronary artery disease. Here is the critical difference. LDL measures the concentration of cholesterol contained within LDL particles. ApoB counts the actual number of atherogenic particles circulating in your arteries, each of which carries exactly one ApoB molecule. Particle number, not cholesterol concentration, is what determines how much damage is being done to arterial walls. Two people can have identical LDL cholesterol with very different ApoB levels, and therefore very different true cardiovascular risk. A high ApoB level, even with a normal LDL, signals an elevated risk that standard lipid testing would miss entirely.
Full lipid panel (Total cholesterol, LDL, HDL, Triglycerides)
The complete lipid profile provides the clinical foundation of cardiovascular risk assessment and gives context to the ApoB result. Triglycerides are particularly informative. Elevated triglycerides are closely linked to insulin resistance and metabolic syndrome, and they are one of the most sensitive dietary markers in the panel. A drop in triglycerides following nutritional intervention is one of the earliest measurable signs that metabolic health is improving.
HbA1c & HOMA index
Together, these two markers reveal the complete picture of glucose metabolism and insulin sensitivity. HbA1c captures average blood sugar over three months, a window that a single fasting glucose measurement cannot provide. The HOMA index quantifies insulin resistance directly, using fasting glucose and fasting insulin together. Insulin resistance is the metabolic root condition that drives abdominal fat accumulation, cognitive decline, chronic inflammation, elevated triglycerides, and accelerated cellular aging, typically for many years before blood sugar levels become abnormal enough to generate any clinical concern. Early detection through a metabolic blood test in Zurich is the difference between a dietary correction and a decade of progressive metabolic damage.
Cortisol
Chronic cortisol elevation is a powerful and under-appreciated driver of metabolic dysfunction. Sustained high cortisol promotes visceral fat storage specifically around the abdomen, suppresses immune function, elevates blood sugar, and drives systemic inflammation. A single morning cortisol measurement provides a clear snapshot of the adrenal stress response and flags whether chronic stress is actively accelerating your metabolic aging.
TSH basal
Thyroid function governs the speed of virtually every metabolic process in the body. Even subclinical hypothyroidism, which does not yet meet the clinical threshold for a diagnosis, measurably elevates LDL cholesterol, slows metabolic rate, increases cardiovascular risk, and impairs cognitive performance. For a longevity-focused panel, TSH provides the essential metabolic baseline.
Liver function (ASAT, ALAT, GGT)
The liver regulates cholesterol synthesis, clears metabolic waste, metabolizes hormones, and manages the inflammatory response. Liver enzyme elevation, even at levels well within the broad clinical reference ranges, is a sensitive early marker of metabolic stress. GGT in particular has been identified in research as an independent predictor of cardiovascular and metabolic risk beyond its traditional role as a liver function marker.
Ferritin & Iron
Iron stores are increasingly studied in the context of cardiovascular and metabolic health beyond their classical role in energy and haemoglobin production. Elevated ferritin is an independent marker of systemic inflammation and a component of metabolic syndrome in a significant proportion of affected individuals. Iron stores that are too high, not just too low, can be clinically relevant in this context.
Vitamin D
Vitamin D deficiency is associated with increased cardiovascular risk, insulin resistance, impaired immune function, cognitive decline, and accelerated biological aging. In Switzerland, vitamin D insufficiency is extremely prevalent, affecting a significant majority of adults during autumn and winter months. In the context of a longevity panel, vitamin D is not simply a nutritional marker. It is a metabolic and immunological one.
High-sensitivity CRP (hsCRP)
Standard CRP detects acute inflammation from infection or injury. High-sensitivity CRP is a different measurement that detects the low-grade, chronic, systemic inflammation that produces no obvious symptoms but silently damages blood vessels, brain tissue, and metabolic organs over years. Research consistently identifies elevated hsCRP as one of the strongest independent predictors of cardiovascular events and metabolic disease. It is a direct measure of the inflammatory environment in which your cells are aging.
FSH (women under 50)
Follicle-Stimulating Hormone rises as ovarian function declines, making it the most reliable early marker of the perimenopausal transition. But this transition is far more than a reproductive event. It is a metabolic inflection point. The progressive decline in oestrogen that accompanies rising FSH directly increases cardiovascular risk, accelerates bone mineral loss, alters insulin sensitivity, and affects cognitive function and mood. For women under 50, FSH provides critical context for interpreting the entire Metabolic Check-up and allows the nutritionist to design a plan specifically adapted to the hormonal and metabolic changes of perimenopause.
Beyond LDL cholesterol: why ApoB changes everything
For decades, patients and doctors alike have used LDL cholesterol as the primary indicator of cardiovascular health. But the limitation of LDL is fundamental, not technical. LDL measures how much cholesterol is being carried in particles, not how many particles there are. The number of particles is what determines how frequently arterial walls are being exposed to atherogenic contact. Two people with identical LDL levels can have particle counts that differ by a factor of two or three, with correspondingly different true cardiovascular risk. This discrepancy is most pronounced in people with metabolic syndrome, insulin resistance, elevated triglycerides, or low HDL, precisely the population for whom LDL most dangerously underestimates risk.
ApoB closes this gap entirely. By including ApoB in every Metabolic Check-up, Labology gives you the same level of cardiovascular risk assessment that leading preventive medicine clinics in the US, UK, and Switzerland now consider the minimum acceptable standard. Our nutritionist Elodie Brocas uses your ApoB result alongside the full metabolic panel to build a targeted nutrition plan aimed at reducing your specific cardiovascular risk profile at the dietary level.
A longevity blood test combined with personalized nutritionist guidance
The Metabolic Check-up is not just a collection of markers. It is a structured conversation between your biology and a certified nutritionist in Zurich who understands how each data point connects to your lifestyle, your symptoms, and your long-term health goals. Elodie Brocas at The Good Life Specialist reviews your complete results and provides a personalized nutrition and health plan that translates the data into concrete, specific dietary recommendations. Whether the priority is reducing insulin resistance, lowering ApoB and triglycerides, addressing low-grade inflammation, supporting hormonal balance during perimenopause, or optimizing vitamin D and metabolic function, your nutrition plan is built around what your results specifically reveal. This is what transforms a longevity blood test in Zurich into a genuine, measurable tool for healthier aging.
FAQS
-
LDL measures the concentration of cholesterol within LDL particles but tells you nothing about how many particles are present. ApoB counts the actual number of atherogenic particles directly, since each particle carries exactly one ApoB molecule. Research in preventive cardiology consistently shows that particle number is a stronger predictor of atherosclerosis and cardiovascular events than cholesterol concentration. This is especially important in people with metabolic syndrome, insulin resistance, or elevated triglycerides, where LDL commonly underestimates true cardiovascular risk by a significant margin. Our nutritionist uses your ApoB result alongside triglycerides and the HOMA index to provide targeted dietary recommendations for reducing your actual particle burden.
-
The HOMA index is calculated from fasting glucose and fasting insulin measured together. It quantifies how efficiently your cells respond to insulin and whether your pancreas is compensating for declining cellular sensitivity by producing more and more. Insulin resistance develops gradually and silently, typically over 10 to 15 years before blood sugar levels become high enough to trigger a diabetes diagnosis on a standard test. During that entire period, it is actively driving abdominal fat accumulation, chronic fatigue, elevated triglycerides, cognitive decline, and systemic inflammation. A metabolic blood test in Zurich that includes the HOMA index catches this process at a stage where dietary and lifestyle intervention can reverse it completely.
-
FSH rises as ovarian function declines, providing the earliest reliable biological marker of the perimenopausal transition. This matters in a metabolic context because the decline in oestrogen that accompanies rising FSH triggers specific metabolic changes that directly affect cardiovascular risk, bone density, insulin sensitivity, and cognitive function. For women under 50, knowing whether the perimenopausal transition has begun changes the interpretation of every other marker in the panel and allows the nutritionist to design a nutrition and health plan that addresses the hormonal and metabolic realities of that specific phase of life.
-
This panel is designed for anyone who wants to take a proactive approach to their long-term health before symptoms appear. It is particularly relevant for people over 35 with a family history of cardiovascular disease or diabetes, anyone experiencing unexplained weight gain around the abdomen, brain fog, declining physical or cognitive performance, or persistent fatigue despite normal basic blood tests, and women approaching perimenopause. If your last nutrition blood test in Zurich or Geneva told you everything was normal but something still feels off, the Metabolic Check-up is where to start.
