When sperm cells are not present, a second confirmatory test, the p30/PSA test, is performed. PSA(p30) is known as a prostate-specific antigen that is produced by the prostatic gland in males. The p30/PSA test is an immunochromatographic test that detects the presence of the antigen p30 in semen samples.
common presumptive test for detecting semen is called the acid phosphatase (AP) test. The AP test detects the enzyme acid phosphatase that is secreted from the prostate gland. ... Confirmatory tests for semen include the christmas tree stain and the p30/PSA RSID kit.
