Acid phosphatase (ACP) catalyzes the removal of phosphate groups at acid pH

Acid phosphatase is found in the prostate, bone, liver, spleen, kidney, RBC's, and platelets.

Acid phosphatase is primarily used to diagnose prostate cancer.

Normal values for acid phosphatase are 2.5-11.7 units/L in males, and 0.3-9.2 units/L in females
