The verdict
Pick Marek Health if you want one 80+ biomarker draw with a coached, written review and a path into hormone-optimization treatment. Pick TestWell if you want specific tests or panels in 1-3 business days at a much lower entry price, with Quest, Labcorp, or BioReference in NY/NJ.

Where does TestWell win?
- •Results in 1-3 business days for most tests vs. roughly two weeks at Marek
- •A much lower entry point — single tests from $21.99 and focused panels from $79.99, vs. a $495 flagship panel
- •Choice of Quest OR Labcorp at checkout, plus New York and New Jersey via BioReference (Marek is Quest-only and excludes NY/NJ/RI/HI)
- •Physician authorization is included in the listed price — no separate venipuncture or requisition fee on standard orders beyond the $6 processing fee
- •Condition-specific panels (GLP-1 monitoring, TRT Quarterly, Menopause, Fertility) sized for follow-up testing rather than one large annual draw
Where does Marek Health win?
- •The flagship panel is genuinely comprehensive — 80+ biomarkers with LC/MS hormone assays, aimed at people who want the whole picture in one draw
- •Optional 45-minute coached lab review with a long-form written analysis — TestWell's physician review authorizes the order, it isn't a consult
- •A pathway into treatment: qualifying results can enroll in Marek Health's Guided Optimization telehealth program
- •Build-your-own panel from 100+ biomarkers and genetic add-ons (APOE, androgen-receptor CAG repeat) we don't offer
We’d rather be honest about where they have an edge — pick the tool that matches your situation.
When is TestWell not the right choice?
Every service here has real limits, including ours. Skip TestWell — and consider Marek Health or another option — if any of these apply to you.
- You want a clinician consult included. A licensed physician authorizes every TestWell order, but that review is not a visit — there is no call to walk through results unless you bring them to your own provider.
- You can't get to a draw site. TestWell is venous-draw only at Quest, Labcorp and BioReference locations; we don't ship at-home finger-prick kits.
- You live in Rhode Island — we can't serve it yet. New York and New Jersey orders route to BioReference locations only, which means fewer draw sites than Quest or Labcorp offer elsewhere.
- You need insurance billed. TestWell is cash-pay; HSA/FSA cards work and every order gets an itemized receipt, but we don't file claims.
- You need a specialty assay outside our catalog (~150 tests and 60+ panels). The big marketplaces list 1,000–2,000 SKUs; we deliberately don't.
