About this test
A longevity baseline is a set of numbers tied to long-term health, most of which can be changed: ApoB and hs-CRP for heart risk, A1c and fasting insulin for metabolic health, liver and kidney chemistry, thyroid, iron, and vitamin D.
The value is in repeating the same set over years and discussing the trend with a clinician. One draw is a starting point; the numbers that moved are the ones worth a conversation.
