Prior to producing the urine sample for the miR Sentinel™ Prostate Cancer Test your patient does not need to fast. We do ask they meet the following conditions to ensure the most accurate results: 

• The urine sample produced for the test should be at least 1 hour after the patient’s first void  (release) of the day. 
• If your patient has undergone a Digital Rectal Exam (DRE), we ask that they wait at least 72 hours after the exam to produce the sample needed for our test.
