Genetic and Detection Tests

It's important to read the description of each test. Some are pre-biopsy while some are post-biopsy. They are specific and not all of them are suitable for all diagnoses. For more information about a specific test, it's best to reach out directly to the testing company.

Opko Health released the 4KScore Test, a tool designed to help doctors and their patients better predict the presence of high-grade cancer before deciding whether to undergo prostate biopsy. The test measures the blood plasma levels of four different kallikrein proteins derived from the prostate: total PSA, free PSA, intact PSA, and human kallikrein 2 (hK2). These biomarkers are then combined with a patient’s age, DRE status, and prior biopsy results, using a proprietary formula, to calculate the probability of a Gleason score of 7 or higher prostate cancer.The 4Kscore Test is for any man concerned about his risk for high-grade, aggressive prostate cancer, and is especially useful when considering a prostate biopsy. The 4Kscore test provides information that a man and his Urologist can use to make an informed, shared decision about whether or not to perform a prostate biopsy.
