The 4Kscore test result is the probability of finding high-grade, aggressive prostate cancer (Gleason 7 or higher) if a prostate biopsy were to be performed.
A 4Kscore <5.0 is associated with decreased likelihood of a Gleason score ≥7 on biopsy. Prostate biopsy is required for the diagnosis of cancer. The test is not recommended more than once every 6 months.
