Lab options in Texas

Orders placed from Texas can be processed through Quest Diagnostics (the default) or Labcorp, depending on the specific test and your preference. Both maintain extensive networks of patient service centers across the state — most TestWell customers find a location within a 15-minute drive.

For most common tests, both Quest and Labcorp offer equivalent quality. If you have a preference (existing relationship with one lab, or one is meaningfully closer), you can specify lab routing during checkout.

Texas is TestWell's second-busiest state, and the economics explain why: Texas has the highest uninsured rate in the country, so for millions of Texans self-pay isn't a workaround — it's simply how routine blood work gets paid for, and flat upfront pricing beats guessing at a hospital bill. Coverage is anchored by the four big metros — Houston, Dallas-Fort Worth, San Antonio, and Austin each have deep Quest and Labcorp networks — and because requisitions work at any location statewide, people in smaller towns order first and draw on their next city trip.

Major cities served: Houston, San Antonio, Dallas, Austin, Fort Worth, plus dozens of additional cities and towns. Use the lab finder to locate the closest patient service center to your ZIP code.

Common questions in Texas

How do I get blood work in Texas without insurance?

Order online, and a physician licensed for Texas reviews and authorizes the requisition — that's included, no doctor's visit needed. Then walk into any Quest or Labcorp patient service center in the state; Houston and DFW alone have dozens. You pay one flat price at checkout, so there's no bill afterward.

Can I order now and do the draw in a different Texas city?

Yes — your requisition is valid at any Quest or Labcorp location, not tied to one site. Order from anywhere in Texas and complete the draw in whichever metro you're in next; results post to your portal in 1-5 business days either way.
