The Immunohistochemistry Laboratory provides a broad range of immunohistochemical stains for paraffin sections of fixed tissues, and selected in situ hybridization and immunofluorescence procedures. In addition to the routine antibodies used in general diagnostic anatomic pathology practice, the Immunohistochemistry Laboratory offers a large selection of less commonly used, or "esoteric" antibodies that may not be available or practical to implement in general diagnostic laboratories. Our antibody menu currently includes over 200 different antibodies to tumor antigens, proliferation markers, infectious agents, and other normal and abnormal tissue antigens. New antibodies are developed as needed by our customers. We also offer different detection/chromogen systems, so that stains can be tailored to the particular needs of the customer. The Lab is staffed by 11 fulltime histotechnologists, 5 of whom have earned Added Qualification in Immunohistochemistry (QIHC) certification from the American Society of Clinical Pathologists. The Laboratory is overseen by a board certified pathologist, and draws upon the expertise of many of the faculty of the UT Southwestern Department of Pathology in implementation and ongoing quality control of stains that we offer. Blocks may be transported to the Lab by courier, US Mail, overnight delivery service, or other appropriate means. Paraffin blocks received by 2:30 p.m. are generally stained the morning of the next working day and sent out that day for interpretation by the submitting pathologist. Appropriate positive and negative control slides are returned with the stained sections. UT Southwestern faculty pathologists are available to offer full diagnostic consultation on submitted cases if requested.
