What is measured in the MPS2 test?

MPS2 is a biomarker test that analyzes 18 unique gene transcripts in your urine to determine your risk of prostate cancer. Among these is the novel gene fusion T2:ERG, which is present in most men with prostate cancer and is the most specific prostate cancer biomarker available. MPS2 is the only test on the market to detect the T2:ERG gene fusion.
