4Kscore® is a blood test used by health care professionals to improve the accuracy of prostate cancer diagnosis after an abnormal prostate-specific antigen (PSA) test result, and before a decision is made to biopsy. The 4Kscore® Test measures four prostate protein levels in a patient's blood, including PSA. By combining the levels of four proteins with certain medical information, the 4Kscore® provides a more accurate assessment of a patient's chance of having an aggressive form of prostate cancer.
