Diagnostic Utility

Prostatic specific acid phosphatase is synthesized in the secretory epithelium and is present in large amounts in prostate gland. It is considered a more sensitive, though less specific, marker than PSA for prostatic differentiation. PSAP complements PSA and NKX3.1, and is helpful in determining the primary site of origin of metastatic carcinoma in a proper clinical setting.
