Frequently asked questions for Vascular Studies
Why do I have to fast for a LEAD test?
The abdominal portion requires patients to fast. The leg arteries begin in the abdomen, not the groin. Ultrasound is used to evaluate the leg arteries even in the belly. If air is in the belly, the ultrasound cannot penetrate. If there is excess fluid in the belly, it creates air, which can block the ultrasound.
Do the vascular studies use needles or dye?
No, the vascular tests use just ultrasound and blood pressures.
Frequently asked questions for Stress Testing
How long will my test take?
Please allow time for registration, pre-test questions, preparation of the testing, post-test questions, and technical review. For regular stress tests and stress echocardiograms, allow one hour. For nuclear stress tests, allow four to six hours.
May I eat before my test?
You may eat a light meal two hours before your stress test. You may also bring a light snack to have after the stress test.
What should I wear?

May I take my medication before my test?
You should take half of your insulin dose on the morning of the test. Please see your test instructions for specifics.
