Know more about this test

A PSA Test is taken to detect whether a person has developed prostate cancer. Prostate Specific Antigen (PSA) is a protein secreted by the prostate gland. This protein is produced by normal as well as cancerous cells. Cancerous prostate gland start multiplying the production of the PSA at an abnormal rate. This test measures the PSA levels (both free and total) in blood. PSA is considered to be a tumor marker since its levels in the blood are elevated in prostate cancer. It serves as a useful tool to monitor the progression of prostate cancer. The most frequent conditions that cause an elevation in PSA level are prostatitis (inflammation of the prostate) and benign prostatic hyperplasia (BPH).

Contains 2 tests

Prostate Specific Antigen (Total) PSA

The PSA Test measures the total PSA levels (both free and bound) in blood.

PSA is a protein which is secreted by the prostate gland. The prostate gland is a male accessory reproductive organ, the secretion of which contributes to the formation of the seminal fluid. Most of the PSA produced is secreted in the seminal fluid along with prostatic secretions and only a small amount is secreted into the bloodstream. PSA is considered to be a tumor marker since its levels in the blood are elevated in prostate cancer and BPH, and it is used as a preliminary screening test before further diagnostic procedures.

PSA in blood is found as either complexed PSA (bound to other proteins) or free PSA. The PSA Test usually calculates the total PSA levels in blood including both free and complexed forms. Separate tests for the levels of these two forms can be used to distinguish between prostate cancer and BPH.

PSA in blood is found as either complexed PSA (bound to other proteins) or free PSA. The PSA Test usually calculates the total PSA levels in the blood including both free and complexed forms, whereas the PSA (Free) test measures the levels of unbound or free PSA in blood.

Some doctors prefer to measure free PSA in patients with a total PSA level between 4 ng/ml and 10 ng/ml rather than subjecting everyone with an elevated PSA to a biopsy as it is an invasive procedure.
