Among Texas orders September 2025 – September 2026, the most-ordered item was TSH + Free T4. ## Lab options in Texas Orders placed from Texas are drawn at **Quest Diagnostics** (the default) or **Labcorp**, chosen at checkout. Both run extensive networks of patient service centers across the state; results are clinically equivalent, so pick whichever is closer. Texas is one of TestWell's three busiest states (with Florida and California), 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. ## What do people in Texas order most?
