Prostatic acid phosphatase, technical only
Use
Prostatic acid phosphatase (PSAP) is strongly expressed in both normal and neoplastic prostatic tissues. This antibody is useful in determining prostatic origin of neoplasms in non-prostate tissues (metastatic disease) and differentiating between prostatic and urothelial carcinomas or mesonephric remnant hyperplasia. Technical component only. Pathologist read not included.
Special Instructions

Specimens must be tested 3 months after placing in ethanol. Collection sites must adhere to prescribed fixation times and storage conditions to ensure sample integrity.
