The 4Kscore®
The 4KScore® Test is an in vitro assay panel that combines blood levels of four prostate specific antigens (free, total, human kallikrein2 (hK2), and intact PSA) in a proprietary algorithm that accounts for a patient’s age, previous biopsy results, and, optionally, a digital rectal exam (DRE). The 4KScore® Test is used by health care professionals to help decide whether a prostate biopsy is necessary in men who are found to have abnormal PSA or DRE. The 4KScore® Test serves to predict a patient’s risk probability for finding aggressive (Gleason score 7 or higher) prostate cancer upon biopsy. The 4Kscore® Test can be used prior to biopsy, or after a negative biopsy, and can predict the likelihood of metastasis the next 15-20 years
