ACID PHOSPHOTASE - PROSTATIC FRACTION

Note:  Serum markers are not specific for malignancy and values may vary by method.

Limitations:   Prostatic Acid Phosphatase (PAP) must not be regarded as an absolute test for malignancy since other factors, including benign prostatic hyperplasia, prostatic infarction, and manipulation of the prostate gland may result in elevated serum PAP concentration. PAP measurements provide little additional information beyond that provided by PSA measurements. Human anti-mouse antibodies (HAMA) may be present in specimens from patients who have received immunotherapy utilizing monoclonal antibodies. Other heterophile antibodies also may be present in patient specimens. This assay has been specifically formulated to minimize the effects of these antibodies on the assay. However, carefully evaluate results from patients known to have such antibodies
