An immunohistochemistry (IHC) staining request for each antibody is requested to obtain the in-depth and precise nature of cellular morphology and function. The test involves staining tissue sections with IHC markers, developing antigen-antibody binding, a detection system, and microscopy to facilitate protein visualization with specific antibodies. IHC adds value to characterizing the nature of tumors, determining specific disease sub-types, and personalizing targeted therapies.
