Test Overview

Chemiluminometric Immunoassay

Test Usage

Predicting recurrence after radical prostatectomy for clinically localized prostate cancer and following response to androgen ablation therapy, when used in conjunction with PSA.

Reference Range *

< or = 2.1 ng/mL

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Prostate specific antigen (PSA) is more sensitive and specific than prostatic acid phosphatase (PAP) for both screening and monitoring patients with prostate cancer; only 13% of patients with an elevated serum PSA concentration after radical prostatectomy have an elevated PAP level.
