Rapid quality control test TPS-402

for antigensPSAserum

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).

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.
