Best Biological Age Tests, Compared
In-depth comparisons and rankings
Which blood tests are best for tracking longevity?
ApoB, Lp(a), HbA1c and hs-CRP predict long-term health in large studies and cost little — here is the core longevity panel and what to skip.
Read the guide →Grip strength testing for longevity: a five-second measurement with more mortality evidence than most blood tests
Grip strength predicts mortality more strongly than blood pressure in a 140,000-adult study, though most home dynamometers were never validated against it.

Hypertension is the single largest modifiable driver of death worldwide, yet most home blood pressure monitors sold never passed independent accuracy testing.
Read the guide →Continuous glucose monitors for people without diabetes: what the evidence actually supports
Over-the-counter CGMs are FDA-cleared as wellness devices, not proven to change outcomes in non-diabetics — evidence is strongest for early insulin resistance.

Blood pressure and lipid panels rank highest for monitoring lifespan efforts; 'biological age' tests rank last with no proven action to take on the result.
Read the guide →VO2 max testing for longevity: what it measures, and what the evidence actually shows
A 122,000-patient study found each 1-MET rise in fitness cut all-cause mortality 13–15%. What VO2 max measures, and why lab tests beat watch estimates.
Read the guide →Biological age tests: what they measure and what they miss
Epigenetic clocks are real science with real limits. What each test measures, how much your result can move between draws, and when it changes a decision.
Read the guide →What is the most accurate early disease detection method?
Colonoscopy, low-dose CT and coronary calcium rank above multi-cancer blood tests and whole-body MRI on accuracy and whether acting on results helps.
Read the guide →How to choose the best early disease screening?
Early disease screening should be judged by five questions in order, starting with your actual risk — most marketed tests target people already at low risk.

Full-body screening ranked organ by organ: the best test for heart, metabolic, kidney, liver, thyroid, colon, breast and prostate beats one whole-body scan.
Read the guide →Advanced early disease detection technology for high risk patients.
Advanced detection earns its place only where risk is high and defined: low-dose CT for smokers, breast MRI for BRCA carriers, ctDNA monitoring after cancer.
Read the guide →Premium early disease detection program for preventive healthcare.
