The 4Kscore Test calculates your risk for aggressive prostate cancer by measuring several proteins in the blood and combining that with clinical findings.

It can be used after an abnormal PSA result if you are considering a prostate biopsy.

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.
