Greater Specificity for Better Biopsy Decisions
Because PSA testing is not specific to prostate cancer, it’s not always a reliable tool to determine which patients should be considered for prostate biopsies.
The IsoPSA Test is different: it advances prostate cancer risk assessment by analyzing the concentration and the structure of cancer-related PSA proteins.
The IsoPSA Test report also includes a total PSA result to eliminate the need to order a separate PSA test.
