How to get a blood test in St. Louis
- Choose your tests — single markers or a panel — and check out. A licensed physician reviews and authorizes the order, usually within minutes, and the requisition is emailed to you.
- Walk into any Quest Diagnostics and Labcorp location above for the lab you picked at checkout. Bring the requisition (on your phone is fine) and a photo ID. Fasting tests are easiest first thing in the morning; most centers open by 7 a.m.
- Results post to your TestWell portal in 1–3 business days with reference ranges and a physician review, and you can download the report to share with your own doctor.

Frequently asked questions
- Do I need an appointment for a blood draw in St. Louis?
- Most Quest Diagnostics and Labcorp patient service centers in St. Louis take walk-ins; Quest and Labcorp also let you book a time slot on their sites, which shortens the wait at busy locations. Order your test on TestWell first — the physician-authorized requisition is emailed within minutes — then bring it and a photo ID to any location listed here.
- Can I get blood work in St. Louis without a doctor or insurance?
- Yes. Missouri allows direct-access testing, and TestWell's licensed physician network authorizes every order as part of the price. Order online, choose Quest or Labcorp at checkout, and walk into any location listed here — no insurance, referral or office visit, with HSA and FSA cards accepted.
- How much does a blood test cost in St. Louis?
- The same as everywhere on TestWell: the test's listed price plus one $6 lab processing fee per order, with no draw fee or physician fee at the location. Common tests such as a CBC, CMP or TSH are in the low tens of dollars; panels bundle several tests at a discount. Prices are on each test page and are the same at every St. Louis location.
- Which location should I choose — Quest Diagnostics or Labcorp?
- Whichever is closer or has hours that fit. Quest Diagnostics and Labcorp are both CLIA-certified national laboratories and results are clinically equivalent; a few specialty tests are available at only one of them, which the test page states. Pick the lab at checkout and the requisition is written for that network.
- How long do results take from a St. Louis draw?
- Most routine results post to your TestWell portal in 1–3 business days after the draw, with each value shown against its reference range and reviewed by a physician; specialty tests take longer, and each test page states its turnaround.
