Prostate Specific Antigen (PSA) Rapid Test
The PSA gold Rapid Screen Test (RST) is a Chromatographic immunoassay (CIA) for direct qualitative detection of prostate specific antigen (PSA) in human serum/plasma or whole blood.
PSA is a normal secretion that secreted by normal prostatic epithelial cell and malignant cancer of prostate. PSA is normal product, but when its concentration exceed over 4ng/ml, it can be taken as an index to the risk probability of prostate cancer. The prostate cancer is the most frequent malignant tumor in male; PSA is considered as the most valuable tumor maker, so the detection of high level of PSA is a specific and effective way to diagnose the prostate cancer, also an index to examine the cancer relapse and therapy monitoring.
The PSA RST is a chromatographic immunoassay (CIA) for the detection of PSA in human serum/plasma or whole blood. Specific antibody against PSA is pre-coated onto membrane as a capture reagent on the test region. During the test, specimen is allowed to react with the colloidal gold particles, which have been labeled with other specific antibodies. If PSA present, a pink colored band will develop on the membrane in proportion to the amount of PSA presented in the specimen. Absence of this pink colored band in the test region suggests a negative result. To serve as a procedural control, a pink colored band in the control region will always appear regardless the presence of PSA.
