Will I need to do anything to prepare for the test?
You may be asked to avoid certain foods for two to three days before the test. These include:
Caffeinated foods and drinks, such as coffee, tea, and chocolate
Bananas
Citrus fruits
Foods that contain vanilla
You may also be asked to avoid stress and vigorous exercise before your test, as these can affect cathecholamine levels. Certain medicines may also affect levels. Be sure to tell your provider about all the medicines you are taking.
