Prostate Specific Antigen (Free) PSA near me in Ahmedabad

The Prostate-Specific Antigen (Free) Test measures the levels of unbound or free prostate-specific antigen (PSA) in blood. PSA in the blood is found as either complexed PSA (bound to other proteins) or free PSA. Free and total PSA tests can help diagnose prostate problems including prostate cancer. However, the results are only meaningful when compared with those of a total PSA test.

A higher ratio of free PSA to total PSA indicates a lower risk of prostate cancer. On the other hand, a low ratio of free PSA to total PSA indicates a higher risk of having prostate cancer. Free PSA tests are quicker, cheaper, and less invasive than biopsies, but they cannot confirm or rule out cancer. If the levels initially indicate a possible risk of prostate cancer, a biopsy might be recommended.
