Acid phosphatase is present in several tissues including prostate, red blood cells, white blood cells, platelets, bone, liver, spleen and kidney. Increased serum levels may be found in prostatic adenocarcinoma, especially when it extends from the gland or has metastasized. Levels may also be increased in certain bone diseases (e.g., metastatic tumors, Paget's disease, Gaucher disease, Niemann-Pick disease and hairy cell leukemia. Levels are increased in hemolysis. Thus, hemolyzed samples are not acceptable.
Acid phosphatase together with prostatic acid phosphatase are most commonly used in the diagnosis and monitoring of prostatic adenocarcinoma. However, PSA is much more commonly used for this purpose. An increased level of non-prostatic acid phosphatase may very occasionally be helpful in diagnosis of the non-prostatic conditions described above.
