Molecular Diagnostics Laboratory

Laboratory Overview

The Molecular Diagnostics Laboratory is operated as a reference laboratory by the Department of Pathology at UT Health San Antonio. The laboratory is involved in teaching medical students, residents, and fellows, and also provides support services for faculty and staff of UT Health, as well as services to outside entities on a fee-for-service basis.

The laboratory develops and performs molecular diagnostic tests for nucleic acid targets found in a variety of settings in medicine. The primary focus of the laboratory is hematopathology; a selection of genetic and infectious disease tests are also performed.

The Molecular Diagnostics Laboratory is fully accredited by and participates in the College of American Pathologists (CAP) inspection and accreditation programs.

Through the deemed status granted to the CAP, the laboratory is also accredited by the Health Care Financing Administration through the Clinical Laboratory Improvement Act (CLIA) for the performance of high complexity testing. Current certificates of accreditation may be viewed here: CAP, CLIA.*
