Getting ready for your test

Before your test, tell your doctor or nurse if you are:

  • Pregnant or think you may become pregnant
  • Diabetic

You may need to have blood drawn if you:

  • Are over 60 years of age
  • Have diabetes
  • Have kidney problems
  • Have medical problems that affect how your kidneys work

If you have had blood drawn recently you may bring those results with you.

Food

  • Do not eat, drink carbonated drinks, or smoke for two hours before your test.
  • Do not drink anything for one hour before your test.
    • Be sure to drink clear liquids, such as water, tea, broth, or apple juice before that time so that you do not get dehydrated.
  • If you have any other test on the same day where you are told not to eat or drink for a longer amount of time, follow those instructions.

Medicine

  • You may take all of your prescriptions medicines up until one hour before your test.

Driving

You will need somebody to drive you home after your test if you are given:

  • Pre-medicine for an allergy, such as Benadryl
  • Medicines to help you relax during the test

If you cannot do the prep listed above, you may not be able to have the test done or it may need to be rescheduled.
