Your shortlist.

Tiny Health

The first gut microbiome test for babies (ages 0–3), plus kits for kids, adults, and vaginal health — built for families who want to catch gut imbalances early. Founded by a mom after a C-section left her without answers; HSA/FSA eligible.

LetsGetChecked

Home health testing with an added layer of care: kits ship to your door, samples go to accredited labs, and nurses call to explain flagged results. Covers hormones, sexual health, heart, and more.

GlycanAge

A biological age test that reads something the methylation clocks don't: glycans on your IgG antibodies, a marker of chronic inflammation that can shift up to a decade before symptoms. Finger-prick kit at home, results in a few weeks — a genuinely different second opinion on how fast you're aging.

Everlywell

At-home test kits for dozens of concerns — thyroid, food sensitivity, STIs, metabolism — with finger-prick or swab collection, CLIA-certified lab processing, and physician-reviewed digital results.

TruDiagnostic

Epigenetic testing from a finger-prick sample: measures DNA methylation to estimate biological age and pace of aging using research-grade clocks. The de facto standard for tracking whether interventions are working.

Viome

Gut microbiome and cellular-health testing from stool and blood samples, translated into personalized food scores — what to eat, what to avoid — plus optional made-to-order supplements.
