You do not need to fast prior to producing your urine sample for the miR Sentinel™ Prostate Cancer Test. We do ask you to meet the following conditions to ensure you receive the most accurate results: 

• The urine sample for the test should be produced at least 1 hour after your first void (release) of the day. 

• If you have undergone a Digital Rectal Exam (DRE), we ask that you wait at least 72 hours after your exam to produce the sample needed for our test.
