Longevity blood tests compared

Quick answer

If you want the lowest entry price, Superpower was cheapest at $199 for one panel a year ^[1]. If you want two draws a year and the largest menu, Function Health listed 160+ tests for $365 ^{[4] [2]}. InsideTracker costs more per test and covers fewer markers, but it lets you buy two or four tests at once ^[3]. Lifeforce tests every three months and adds coaching, at a higher yearly cost ^[5].

What the extra markers add

A marker count does not tell you which results will change your care. Marker counts are company figures. Ask which markers are tested, how out-of-range results are handled, and who orders follow-up tests.

We did not find a US guideline body in our research that recommends 100+ marker panels for healthy adults. Where guidelines do use extra testing for prevention, they target it. For example, the ACC/AHA cholesterol guideline uses a coronary calcium score only for adults 40 to 75 at intermediate risk when a statin decision is unclear ^[6].

Costs that are easy to miss

• Renewal price. Function Health says the $365 offer renews at the then-current price ^[2].
• At-home draws. Superpower charges $99 extra for a home visit ^[1].
• Extra tests. Function Health charges members for on-demand tests and does not publish add-on prices for MRI, Galleri or other options ^[4].
• Follow-up care. An abnormal result may lead to a visit with your own doctor and repeat labs, billed through your insurance or in cash.

Who each one fits

• Superpower: people who want one broad panel a year at the lowest list price.
• Function Health: people who want two draws a year and access to imaging add-ons through Ezra MRI.
• InsideTracker: people focused on nutrition and fitness tracking who want to buy several tests up front.
• Lifeforce: people who want quarterly testing with coaching, and accept a monthly fee. See our Lifeforce review.
