Immunocytochemistry The Immunohistochemistry Laboratory provides clinical testing on surgical 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. Following the latest CAP guidelines, we provide testing which supports treatment planning by the clinician and the patient. Some examples would be Estrogen and Progesterone Receptors, Her2-neu protein expression, EGFR and CKit testing. Immunohistochemistry Consultants P.
