Laboratory Services

Oftentimes, before your doctor can make an accurate diagnosis, they will order blood, tissue or urine tests. These tests reveal important information about your body’s inner processes and can provide your doctor with critical details to inform your treatment path.

Critical Programs We Support

In addition to routine testing, our lab tests provide critical information to a number of University Health’s lifesaving programs, including:

• Emergency services – Our laboratory provides the Level I trauma team with vital test results around-the-clock to support treatment for injured and ill patients.
• Transplant program – We perform essential HLA identification, which helps find an organ or stem cells that might be a good transplant match. We also perform crossmatch tests for adult and pediatric patients within the transplant program, which can help determine if donor tissue is compatible with the recipient. We also are extensively involved in the living donor programs for kidney and liver transplants.
• Dialysis clinics – We provide lab services to patients at our Texas Diabetes Institute (TDI), one of the nation’s largest and most comprehensive centers dedicated to diabetes prevention, treatment, research and education.
