The PSA test is used primarily to screen for prostate cancer. A PSA test measures the amount of prostate-specific antigen (PSA) in your blood. PSA is a protein produced in the prostate, a small gland that sits below a man's bladder. PSA is mostly found in semen, which also is produced in the prostate. Small amounts of PSA ordinarily circulate in the blood. The PSA test can detect high levels of PSA that may indicate the presence of prostate cancer. However, many other conditions, such as an enlarged or inflamed prostate, can also increase PSA levels. We use ImmunoAssay for Quantitative Measurement of PSA in Human Blood / Serum / Plasma with i-CHROMA TM Reader System with high sensitivity and specifity. We have analysed 120 patients and only 2 of them had very high value of PSA so we can determine for a prostate cancer. Additional factors increase the accuracy of PSA testing and it is not sufficient only the PSA to determine a prostate cancer so we need a rectal examination and transrectal ultrasound.
