Prostate-Specific Antigen Rapid Test – Product code: SC-0890-40

Rapid test for the qualitative diagnosis of Prostate Specific Antigen (PSA) in whole blood, serum or plasma. For professional in vitro diagnostic use only. The Prostate Specific Antigen PSA Semi-Quantitative Rapid Test (Whole Blood/Serum/Plasma) is a rapid chromatographic immunoassay for the semi-quantitative detection of Prostate Specific Antigen in whole blood, serum or plasma. The prostate specific antigen (PSA) is produced by the endothelial and glandular cells of the prostate. It is a single chain glycoprotein with a molecular weight of approximately 34 kDa1. PSA exists in three main forms circulating in the serum. These forms are free PSA, PSA bound to α1 – Antichimotrypsin (PSA-ACT) and PSA complex with α2 – macroglobulin (PSA-MG). The prostate specific antigen (PSA) is produced by the endothelial and glandular cells of the prostate. It is a single chain glycoprotein with a molecular weight of approximately 34 kDa1. PSA exists in three main forms circulating in the serum. These forms are free PSA, PSA bound to α1 – Antichimotrypsin (PSA-ACT) and PSA complex with α2 – macroglobulin (PSA-MG). PSA has been detected in various tissues of the male urogenital system, but only the endothelial and glandular cells of the prostate secrete it. The serum PSA level of a healthy man is between 0.1 ng/mL and 2.6 ng/mL. It can be elevated in malignant conditions, such as prostate cancer and in benign conditions such as in the case of benign prostatic hyperplasia and prostatitis. A PSA level of 3 to 10 ng/mL is considered a “gray zone” and levels above 10 ng/mL can almost certainly indicate cancer. Patients with PSA values ​​between 3 and 10 ng/mL should perform additional prostate analyzes such as biopsy. The prostate specific antigen is the most valid tool available for diagnosing the first stages of prostate cancer. Many studies have confirmed that the presence of PSA is the most useful and significant tumor marker known for prostate cancer and prostatic infection of Benign Prostatic Hyperplasia (BPH). The Prostate Specific Antigen Semi-Quantitative PSA Rapid Test Cassette (Whole Blood/Serum/Plasma) uses a combination of colloidal gold conjugate and anti-PSA antibodies to selectively detect total PSA in whole blood, serum or plasma. The test has a cut-off value of 3 ng/ml and a reference value of 10ng/ml. The PSA Quick Test (Whole Blood/Serum/Plasma) is a semi-quantitative, membrane-based test for the detection of PSA in whole blood, serum or plasma. The membrane is pre-coated with anti-PSA antibodies in the test line region. During the test, the reacts with the particle coated with anti-PSA antibody. The compound migrates chromatically upwards on the membrane by capillary action to react with the anti-PSA antibody on the membrane and generate a colored line. A test line (T) of lower intensity than the reference line (R) indicates that the PSA level in the sample is between 3 and 10 ng/mL. An intensity of the test line (T) equal to or similar to the reference line (R) indicates that the PSA level in the sample is greater than 10 ng/ml. As a procedural control, a colored line always appears in the control zone to indicate that the amount of sample used is sufficient and the membrane has been soaked correctly.
