Prostate cancer is the one of the most common types of cancer found in man. The incidence of prostate cancer increases with age and accounts for a growing number of newly diagnosed patients. Prostate specific antigen (PSA) is produced primarily in the prostate gland and is secreted into the prostate ducts and at ejaculation serves to liquefy the seminal coagulum. Virtually all healthy males under 50 years of age have PSA concentration under 4.0 ng/ml. If PSA level is above 20 ng/ml, the patient most likely to have prostate cancer. Some studies indicated that elevated total PSA levels are found in serum from patients who have prostate cancer cells metastasized throughout their bodies. Other studies indicated that Free PSA, which can not foam a complex with serine protease tends to be more abundant in patients with benign prostatic hyperplasia. The PSA test use antibodies which can equally recognize both free PSA and PSA-ACT complex.
The One Step PSA Prostate Specific Antigen Rapid Test Strip (Whole Blood/Serum/Plasma) is a semiquantitative, membrane based immunoassay for the detection of PSA in whole blood, serum or plasma. The membrane is pre-coated with PSA antibodies on the test line region. During testing, specimen reacts with the particle
coated with anti-PSA antibody. The mixture migrates upward on the membrane chromatographically by capillary action to react with anti-PSA antibodies on the membrane and generate a colored line. A test line (T) of weaker intensity than the reference line (R) indicates that the PSA level in the specimen is below 4 ng/mL. A test line (T) intensity equal to the reference line(R) indicates that the PSA level in the specimen is approximately 4 ng/mL. A test line (T) intensity stronger than the reference line (R) indicates that the PSA level in the specimen is above 4 ng/mL. To serve as a procedural control, a colored line will always appear in the control line region (C) indicating that proper volume of specimen has been added and membrane wicking has occurred.
