PSA (Prostate Specific Antigen) Detection Kit

• INTENDED USE

This Product is intended to be used by professionals to quantitative determination of PSA in human serum, plasma in vitro.

• CLINICAL SIGNIFICANCE

PSA (Prostate specific antigen) is a single-chain glycoprotein with molecular weight of 34 kilodaltons. As a serine protease with chymotrypsin-like activity, PSA belongs to the kallikrein family. In blood, PSA exists as a free or complex form with protease inhibitors such as a-1-antichymotrypsin (ACT). Total PSA represents the sum of both free and complex forms. PSA is uniquely associated with prostate tissues from normal, inflamed or cancerous stages. Elevated PSA in blood is found in patients with prostate cancer, benign prostatic hypertrophy, or inflammatory tissues. Studies on a variety of PSA methods have shown that PSA can be useful as an indicator for the diagnosis and management of prostate cancer. PSA has been found in normal, benign hyperplastic, and malignant prostatic tissue, in metastatic prostatic carcinoma, and also in prostatic fluid as well as in seminal fluid. PSA is not found in any other tissue in men, and it is not produced by cancers originating in the lung, colon, rectum, stomach, pancreas or thyroid. Though increased concentrations of PSA are found in the serum of patients with benign prostate hyperplasia (BPH), prostatitis and prostate infections and inflammation, they are also found in patients with cancer of the prostate. PSA measurement is an essential tool in assessing the status of disease in patients with prostate cancer when serial samples are measured over time.
