PSA Test Strip and PSA Test Cassette

PSA rapid test kits, also known as one-step PSA tests, are a rapid direct binding PSA immunoassay for the qualitative detection of Prostate Specific Antigen (PSA) in human serum specimen. Based on the lateral flow chromatography principle, monoclonal and polyclonal antibodies are employed to identify the PSA tumor marker specifically. These in-vitro diagnostic (IVD) rapid PSA Test Kits are used as an aid in the diagnosis of prostate cancer, and also to be used to screen men under higher risk of prostate cancer. Atlas Link Technology Co., Ltd would like to offer quality PSA rapid test Strips and PSA test cassette at competitive prices.

When PSA concentration is higher than 4 ng/mL, two lines will develop indicating a positive result; when it lower, one line on control region and a negative result. The rapid test kits are used to screening men faced with high risk of prostate cancer, usually over 50 years old.

About Tumor Marker PSA

The prostate specific antigen (PSA) is the most commonly tested tumor marker for the prostate gland disease diagnosis. PSA tumor marker is normally present in low levels in the blood of all adult men. In human blood, the normal concentration range of this biomarker is 0.0 to 4.0 ng/ml, which are variable among different human races (refer to the following table). But when the PSA concentration rises beyond the normal range, it can be taken as a signal of prostate gland cancer or other disorders. That is why PSA becomes the subject of PSA serum detection devices.

Prostate cancer is a form of cancer that develops in the prostate, a gland in the male reproductive system. Most prostate cancers are slow in growing. The cancer cells may spread to other parts of the body, particularly the bones and lymph nodes. Prostate cancer may cause pain, difficulty in urinating, problems during sexual intercourse, or erectile dysfunction. A blood test to measure Prostate-specific antigen (PSA) is considered the most effective test currently available for the early detection of prostate cancer. PSA refers to a protein produced by the cells of the prostate gland, which is produced for the ejaculate where it liquifies the semen in the seminal coagulum and allows sperm to swim freely. So, actually PSA is not an antigen. PSA is present in small quantity in the serum of men with healthy prostates, but is often elevated in the presence of prostate cancer and in other prostate disorders such as prostatitis, benign prostatic hyperplasia (BPH). In healthy men, the total PSA level is significantly lower than 4 ng/mL. And PSA levels between 4 and 10 ng/mL are considered to be suspicious of prostate cancer.
