    Most people who take a drug test take a presumptive test, cheaper and faster than other methods of testing. However, it is less accurate and can render false results. The FDA recommends for confirmatory testing to be conducted and the placing of a warning label on the presumptive drug test: "This assay provides only a preliminary result.

    When sperm cells are not present, a second confirmatory test, the p30/PSA test, is performed. [3] PSA(p30) is known as a prostate-specific antigen that is produced by the prostatic gland in males. [9] The p30/PSA test is an immunochromatographic test that detects the presence of the antigen p30 in semen samples.
