What this test reveals
What this test reveals
Organ-specific biological age testing uses blood protein analysis (proteomics) to measure how old each of your organs actually is, independent of your chronological age. Based on research from Stanford University (Dr. Tony Wyss-Coray), this test analyzes approximately 5,000 plasma proteins to generate aging scores for individual organs.
Your organs don't age at the same rate. You might be 45 chronologically, but your heart could be 55 while your liver is 38. This technology identifies which organs are aging faster than others, enabling you to target interventions where they'll have the most impact rather than taking a one-size-fits-all approach to health.
People usually reach for this kind of diagnostic when they want a clearer read on individual biological age for heart, liver, brain, kidneys, immune system, and gut, plasma protein signatures (~5,000 proteins analyzed), organ-specific aging acceleration or deceleration, especially when symptoms or prior testing still leave blind spots.
Once results are back, you can upload them into Gabriel to connect the findings to symptoms, protocols, and next-step testing instead of leaving them as a static report.
Commonly relevant for: Anti Aging Longevity, Heart Disease Prevention, Brain Health Neurodegeneration, Chronic Kidney Disease, Fatty Liver Disease, Autoimmune Disorders.
Gabriel difference
Why this becomes more useful inside Gabriel
Standard biological age tests give you one number. But that single number hides critical information. A patient with rapid heart aging needs cardiovascular-focused interventions, not generic anti-aging protocols. Organ-specific testing lets Gabriel design truly personalized longevity strategies targeting your weakest links. This is precision medicine for aging.
Gabriel interprets results through a functional, root-cause lens: optimal ranges, pattern recognition across multiple diagnostics, and what the findings actually mean for action rather than just classification.
That means this test can feed directly into protocols, practitioner matching, food strategy, and follow-up testing instead of ending as a one-off PDF or lab portal result.
What to expect
What to expect from ordering to results
01
Order
Order directly through TruAge or ask Gabriel whether there is a better path first.
02
Complete
A simple blood draw collected at home or in a lab. The sample is analyzed for thousands of plasma proteins that serve as biomarkers for organ aging.
03
Interpret
Upload the results to Gabriel for pattern recognition, protocol suggestions, and next-step guidance.
Not sure which test belongs in your workup?
Tell Gabriel your symptoms, goals, and what you have already tried. You will get a more useful answer than a generic test catalog can give you.
