Acid phosphatase is an enzyme found in the prostate gland, semen, liver, spleen, blood cells, and bone marrow.
The ACP test is used primarily to diagnose and assess conditions such as cancer of the prostate (diagnose and monitor the effect of the treatment), certain bone diseases (Paget’s disease), prostatitis (infection or inflammation of the gland), hyperparathyroidism, and benign hypertrophy of the prostate gland (BPH).
