This test assists physicians in determining the need for a prostate biopsy in patients with an ambiguous prostate specific antigen (PSA) test result. It tests for three exosomal RNA biomarkers to enable physicians to assess whether a patient presenting for an initial biopsy is at greater risk for high-grade prostate cancer.
