About the 4K Test

​

The 4Kscore was developed to help aid physicians in determining if their patient with an abnormal prostate specific antigen (PSA) blood test or prostate exam may require a prostate biopsy. The 4Kscore provides a percent risk (ranging from 1-95%) of a patient having aggressive prostate cancer on biopsy. This is computed using several different clinical factors. This test has been shown to be far more accurate than PSA in determining if a patient may have aggressive prostate cancer. Unlike PSA, the 4KScore is not influenced by benign prostate conditions, such as infection or an enlarged prostate.
