Understand your biomarkers and health scores
The Precision Diagnostic starts with 100 biomarkers at entry, with up to 125 biomarkers by tier. Our report organizes findings into domain scores for discussion with your clinician. More tests and a score alone cannot establish a diagnosis.
Last updated: September 24, 2026
81 Blood Markers + 19 Urinalysis Markers
The entry set contains 81 blood markers and 19 urinalysis markers. Higher tiers add blood markers, up to 125 biomarkers in total. Confirm which tests your clinician has ordered. The report also considers clinical measurements; routine urinalysis is not comprehensive toxin or hormone-metabolite testing.

Seven areas to discuss with your clinician
Each domain scores 0–100 within our practice-defined reporting framework. These thresholds are not universal diagnostic cutoffs, and a higher score is not proof of better long-term health.
Metabolic Health
20% weightKey markers: Fasting Glucose, Insulin, HbA1c, HOMA-IR
Cardiovascular
20% weightKey markers: ApoB, LDL-C, HDL-C, Triglycerides, Lp(a), TC/HDL Ratio
Inflammation
15% weightKey markers: hs-CRP, Homocysteine, Ferritin, ESR
Hormonal
15% weightKey markers: Total/Free Testosterone, DHEA-S, Cortisol, Estradiol, SHBG, IGF-1
Organ Function
10% weightKey markers: ALT, AST, GGT, BUN, Creatinine, eGFR, Albumin
Blood Health
10% weightKey markers: CBC with differential, Iron, TIBC, Ferritin, B12, Folate
Body Composition
10% weightKey markers: Clinical measurements considered alongside lab results
How the 1836 Functional Bio Age estimate works
The 1836 Functional Bio Age combines seven domain scores and expresses the result relative to chronological age. This proprietary estimate is a discussion tool, not a diagnosis, a lifespan prediction or evidence that aging has been reversed.
100 Markers Collected
The entry set contains 81 blood markers and 19 urine markers. Your clinician reviews the findings alongside symptoms, history and any relevant clinical measurements.
Practice-Defined Composite Scores (0–100)
Findings organized across health areas feed seven composite scores. The weights and score bands describe our reporting approach; they are not independently validated diagnostic thresholds. Laboratory reference ranges and clinical judgment remain part of interpretation.
Composite → Biological Age
The weighted composite is compared with a 75-point midpoint. Each point above or below it shifts the estimate by half a year, capped at 15 years in either direction. A change in this calculated value does not demonstrate longer life, reduced mortality or reversal of biological aging.

vs. Calendar Age
In this historical founder example, the calculated score changed from 54.0 to 48.3 over eight months, while the metabolic domain score changed from 39/100 to 79/100. This is one person's experience, not a clinical trial or a typical-result claim. It does not prove aging reversal or establish that the program caused the change. Individual results vary.
See the full data storyWhat testing can and cannot tell you
Routine preventive care varies with your age, history and clinical needs. There is no fixed number of tests in every annual physical, and additional tests are not automatically better. This service does not replace routine screening, primary care or urgent evaluation.
Reference ranges usually draw on results from healthy reference groups and vary by laboratory and method. A result within range does not rule out every condition; an out-of-range result does not by itself establish a diagnosis. Read MedlinePlus: understanding lab results for background.
Our domain scores and Functional Bio Age are practice-defined summaries. They are not validated diagnoses, predictors of lifespan or proof of age reversal or treatment benefit. Changes should be discussed alongside symptoms, medicines, collection conditions and the underlying results.
For practical next steps, see what the Precision Diagnostic includes and blood-draw preparation and planning. Your clinician decides whether follow-up testing or treatment is appropriate. No prescription or outcome is guaranteed.
