- 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. 7 of the 7 locations here are open by 7:00 AM on weekdays.

Frequently asked questions
- Do I need an appointment for a blood draw in Corpus Christi?
- Most Quest Diagnostics and Labcorp patient service centers in Corpus Christi 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 Corpus Christi without a doctor or insurance?
- Yes. A physician licensed in Texas reviews and authorizes every TestWell order as part of the price, so you need no doctor's visit or referral of your own. Order online, choose Quest or Labcorp at checkout, and walk into any location listed here — no insurance needed, and HSA and FSA cards are accepted.
- How much does a blood test cost in Corpus Christi?
- At Quest Diagnostics in Corpus Christi: CBC with Differential $17.69, Hemoglobin A1c $18.79, 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 Corpus Christi 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 Corpus Christi 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 Corpus Christi 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.
