Prostate Specific Antigen Rapid Test Device/ Strip (Whole Blood/Serum/Plasma)
Prostate specific antigen (PSA) is produced by prostate glandular and endothelial cells. It is a single chain glycoprotein with a molecular weight of approximately 34 kDa.1 PSA exists in three major forms circulating in the serum. These forms are free PSA, PSA bound to α1–Antichymotrypsin (PSA‐ACT) and PSA complexed with α2–macroglobulin (PSA‐MG).2
