How to get a blood test in Seattle
- 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. 4 of the 20 locations here are open by 7:00 AM on weekdays.
- 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 Seattle?
- Most Quest Diagnostics and Labcorp patient service centers in Seattle 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 Seattle without a doctor or insurance?
- Yes. Washington 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 Seattle?
- At Quest Diagnostics in Seattle: CBC with Differential $17.99, Hemoglobin A1c $18.99, plus one $6 lab processing fee per order and nothing at the draw — no draw fee, no physician fee. Prices are set per lab, not per location, so every Seattle site of the same lab charges the same; the table on this page shows each popular test at each lab, and panels bundle several tests at a discount.
- 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.
- Can I pay for blood work in Seattle with an HSA or FSA?
- Yes. Every TestWell test is a qualified medical expense under IRS Publication 502 — pay with the HSA or FSA debit card at checkout, or submit the itemized receipt from your account. For a health FSA the expense counts on the date you are drawn at the Quest Diagnostics and Labcorp location, so a December draw uses this year's balance; HSA money never expires.
- How long do results take from a Seattle 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.
