This PSA Gold Test is a rapid direct binding test for the detection of Prostate Specific Antigen (PSA) in serum as an aid in the diagnosis of prostate cancer. The test is based on the principle of sandwich immunoassay for determination of PSA in serum. Monoclonal and polyclonal antibodies are employed to identify PSA specifically. This one step test is very sensitive and only takes about 10 -20 minutes.

Do You Need a PSA Test? Doctors' recommendations for screening vary. Some encourage yearly screening for men over age 50, and some advise men who are at a higher risk for prostate cancer to begin screening at age 40 or 45.

False positive tests: False positive test results (also called false positives) occur when the PSA level is elevated but no cancer is actually present. False positives may lead to additional medical procedures that have potential risks and significant financial costs and can create anxiety for the patient and his family. Most men with an elevated PSA test turn out not to have cancer; only 25 to 30 percent of men who have a biopsy due to elevated PSA levels actually have prostate cancer.

False negative tests: False negative test results (also called false negatives) occur when the PSA level is in the normal range even though prostate cancer is actually present. Most prostate cancers are slow-growing and may exist for decades before they are large enough to cause symptoms. Subsequent PSA tests may indicate a problem before the disease progresses significantly.
