UTMB Laboratory Services provides Clinical and Anatomical Pathology services to UTMB Hospital and Clinics, the Texas Department of Criminal Justice (TDCJ), and various other community agencies and physicians.
This guide is designed to provide a convenient compendium of information of the services offered by the department, as well as to describe the logistics involved in the ordering of tests. In many instances, the complexities of biological testing in the modern laboratory cannot be completely described in print and users should avail themselves of the expert advice offered by the professional and technical staff of the department.
Note: Tests sent out to ARUP, our primary reference lab, are specified in the test menu and linked to the ARUP search engine.
