Acid Phosphatase
(PAP)

Alternate Names

  • Prostatic Acid Phosphatase
  • TRAP (Tartrate-Resistant Acid Phosphatase)

PAP measures blood levels of acid phosphatase, found mainly in the prostate gland, and is used to diagnose and determine the severity of prostate cancer and to monitor your response to prostate cancer treatment. This test can also be used to diagnose sickle cell crisis, bone diseases, and multiple myeloma. There can be false positive results with this test.

PSA (prostate-specific antigen) level testing is more accurate than PAP, and is replacing PAP as a diagnostic test for prostate cancer. TRAP (tartrate-resistant acid phosphatase), which is similar to PAP, is used to diagnose hairy-cell leukemia and other lymph diseases, but this test is not always accurate.
