Houston is the largest city in Texas and the fourth-largest in the U.S., home to the Texas Medical Center — the world's largest medical complex. Despite this, many patients across the Houston metro still need blood draws but can't easily get to a lab, especially in sprawling suburbs like Katy, Cypress, and The Woodlands.

Mobile phlebotomists in Houston typically serve the entire metro area within a 30–50 mile radius. Services include routine venipuncture for Quest and Labcorp orders, drug and alcohol testing, DOT physicals collections, wellness panels, and specialty draws for clinical trials at MD Anderson and Houston Methodist.

Most Houston-area providers charge $60–$120 per visit for the draw fee, with lab processing billed separately. Medicare patients with homebound documentation typically pay $0–$25.
