The 4Kscore Test, an in vitro serum or plasma test that combines the results of four immunoassays (Roche Elecsys total PSA (prostate specific antigen), Roche Elecsys free PSA, intact PSA, and human kallikrein 2) into a single numerical score that also incorporates the following information: a patient s age, previous biopsy, and digital rectal exam (DRE).
Mathematical modeling of the 4Kscore with and without DRE information was recently performed on over 3,000 specimens. DRE information is a required component of The 4Kscore Test.
