Compare Longevity Blood Tests and Biomarker Panels

Compare five things: what the test measures, how the sample is collected, how the results are interpreted, what action plan follows, and whether you can retest to track change. For a first test, start with the measurements. If a panel does not measure what you want to understand, the other four points matter less.

No. A long list can include many markers that do not relate to your goals, and some totals count calculated values as separate results. A shorter panel that measures the right things, with clear interpretation, can be more useful than a longer list you cannot act on.

A measured biomarker is a value the lab reads directly from your sample, such as ApoB or vitamin D. A calculated index is worked out from two or more measured values. For example, HOMA-IR, an estimate of insulin resistance, is calculated from fasting glucose and insulin. A good report labels the two separately.

Support ranges from raw results in an app, to a written clinician summary, to a live consultation and a personalized protocol. Many services now include some kind of action plan, so check what form it takes and whether a person reviews it with you. Each comparison on this page lists what each company provides after results.

Retest when you have made a change and want to see whether it worked. Some markers respond within weeks, others take months. For example, Jinfiniti suggests rechecking intracellular NAD+ about 4 weeks after starting a protocol, and Klotho or senescence markers after about 3 months. Talk with your clinician about the right schedule for you.
