The Free : Total PSA Ratio test is a blood test that measures the levels of two different types of prostate-specific antigen (PSA) in the blood: free PSA and total PSA. PSA is a protein produced by the prostate gland, and its levels can be elevated in conditions like prostate cancer.
This test is used to help determine the likelihood of prostate cancer in men who have elevated total PSA levels. By comparing the levels of free PSA to total PSA, doctors can get a better understanding of the risk.
If the ratio of free PSA to total PSA is low, it may indicate a higher risk of prostate cancer. On the other hand, if the ratio is high, it suggests a lower risk. This information helps doctors decide whether further testing, such as a prostate biopsy, is necessary to confirm or rule out prostate cancer.
It's important to note that this test alone cannot diagnose prostate cancer, but it provides valuable information that helps guide further evaluation and treatment decisions.
Analyse the levels of prostate specific antigen (PSA), free prostate sepcific antigen and the ratio between them as one way to check the health of your prostate.
Prostate cancer is the commonest cancer in men. Although no diagnosis can be made from PSA testing alone, abnormal results need to be further investigated.
This test is well suited to a finger prick sample as well as a phlebotomy sample.
