The Prostate Specific Antigen (PSA) Free test is a blood test that measures the level of PSA, a protein produced by the prostate gland. This test is commonly used to screen for prostate cancer, as elevated PSA levels can indicate the presence of cancer or other prostate conditions such as inflammation or enlargement. The PSA Free test measures the amount of PSA that is not bound to other proteins in the blood, and can provide a more accurate indication of the likelihood of prostate cancer than the standard PSA test. However, like all medical tests, the PSA Free test has limitations and should be interpreted in conjunction with other diagnostic tools and medical assessments. It is important for individuals to discuss the benefits and risks of PSA testing with their healthcare provider to make informed decisions about their prostate health.
