OnDemand Lab Testing

Most direct-to-consumer blood tests are startups that send your sample to a third-party lab. Labcorp OnDemand skips the middle layer: it is the consumer storefront of Labcorp itself, one of the two national reference labs that already run a large share of US clinical bloodwork.

At-Home Biomarker Test

The at-home blood panel that skips the lab visit and the needle: a small upper-arm sample, up to 60 biomarkers, results in 7-10 days with an AI-built action plan. The lowest-friction way to actually test as often as longevity tracking wants you to.
