What Blood test for prostate cancer?
Prostate-specific antigen (PSA) test: This is a blood test that measures the level of PSA in the blood. PSA is a protein that is produced by the prostate gland. A high PSA level can be a sign of prostate cancer, but it can also be caused by other conditions, such as an enlarged prostate or prostatitis.
Free PSA test: This test measures the amount of free PSA in the blood. Free PSA is a form of PSA that is not bound to other proteins. A low free PSA level can be a sign of prostate cancer.
Prostate Health Index (PHI): This is a blood test that combines the results of the PSA test and the free PSA test to provide a more accurate estimate of the risk of prostate cancer.
4Kscore test: This is a blood test that measures the levels of four different biomarkers in the blood. These biomarkers are associated with prostate cancer. A high 4Kscore can be a sign of prostate cancer.
SelectMDx test: This is a blood test that measures the levels of two different biomarkers in the blood. These biomarkers are associated with prostate cancer. A high SelectMDx score can be a sign of prostate cancer.
