Some people who are given the test never do it or don't give it to their doctor because they
worry that something they ate may interfere with the test. For this reason, many doctors tell
their patients it isn't essential to follow any restrictions in their diet. The most important thing
is to get the test done. People should try to avoid taking aspirin or related drugs for minor
aches. But if you take these medicines daily for heart problems or other conditions, don't stop
them for this test without talking to your doctor first.
