Do I need to fast for my test?

There is no need to fast for most outpatient cardiology tests.  For Abdominal Aorta Ultrasound tests, you will be required to fast for 4 hours. For Renal Ultrasound tests, you will need to fast for 8 hours.  If you have Diabetes, please do not fast before seeking medical advice.  If you are having an inpatient procedure under a Cardiologist, you will be advised as part of your preparation.
