Prostate Triple (P63/KRT/P504S), Technical Component Only
Use
The prostate triple assay consists of 3 antibodies: P63, HMW KRT (34betaE12), and P504S. This multiplex is used in the diagnosis of high-grade prostatic intraepithelial neoplasia (PIN) and prostate cancer. P63 (nuclear) and HMW KRT (cytoplasmic) are expressed in normal myoepithelial cells that surround the prostatic epithelial cells. This myoepithelial layer is lost in carcinoma. The test aids in the identification of high-grade prostatic intraepithelial neoplasia and prostate cancer.
Special Instructions
This test includes only technical performance of the stain and no pathologist interpretation is provided. Technical component only stains should not be ordered with PATHC / Pathology Consultation. If ordered with PATHC, the technical component stains will be canceled.
Limitations
This test does not include pathologist interpretation, only technical performance of the stain. Age of a cut paraffin section can affect immunoreactivity. Stability thresholds vary widely among published literature and are antigen dependent. Best practice is for paraffin sections to be cut within 6 weeks. The charge of glass slides can be affected by environmental factors and subsequently may alter slide staining. Sending unsuitable glass slides can result in inconsistent staining due to poor slide surface chemistry.
