    blood test combining three markers to detect prostate cancer

    The Prostate Health Index (PHI) is a blood test that helps to improve the accuracy of prostate cancer detection. It combines three different prostate-specific markers—total PSA, free PSA, and [-2]proPSA—into a single score, which can help differentiate between benign prostate conditions and prostate cancer, thereby reducing unnecessary biopsies.
