What
is Acid Phosphatase?
Acid
phosphatase is an enzyme found throughout the body, but primarily
in the prostate gland. Like all enzymes, it is needed to trigger
specific chemical reactions. Acid phosphatase testing is
done to diagnose whether prostate cancer has spread to other parts
of the body (metastasized), and to check the effectiveness of treatment.
The test has been largely supplanted by the prostate specific antigen
test (PSA).
