Immunohistochemistry

About Us

The Immunohistochemistry (IHC) Laboratory provides clinical testing on surgical and cytology specimens for proteins, enzymes and infectious agents by immunohistochemical methods. We offer immunohistochemical and in-situ hybridization staining to outside clients with interpretation by our pathologists, or we return them for interpretation to the requesting pathologist.

Our unit provides the university community with extensive knowledge on immunohistochemical testing in both clinical and research settings. Most clinical testing is performed within 24 hours, giving rapid results to pathologists for final diagnosis. 

All of our stains are rigorously validated according to the latest CAP guidelines, providing test results which you can trust as the treatment plan is determined by the clinician and the patient; some examples include Estrogen and Progesterone Receptors, Her2-neu protein over-expression, and PD-L1 testing
