PSAP is fairly specific for prostate tissue
Carcinoids found within the ovary, kidney, breast, liver, and head and neck have been PSAP negative
*both PSAP and PSA reactivity are reported
**reported for antibodies developed against seminal fluid.
PSAP monoclonal antibodies have shown a lower sensitivity compared to polyclonal antiserum (In two studies of poorly differentiated prostate carcinoma, monoclonal antibodies stained 59% and 60% of cases whereas polyclonal antibodies stained 83% and 86% of cases).
