Thanks to a great newsletter from our colleagues at ExamOne for this:

Do’s and Don’ts

Do:

• Get a good night’s sleep:  Ensures the best resting pulse and blood pressure
• Stay hydrated:  Drink a glass of water 1 hour before the exam as it makes for an easier blood draw
• Document medications: Prescription and over-the-counter medications including vitamins, herbs and supplements
• Notify of any past blood draw issues: So the examiner can be prepared and even bring a smaller needle if necessary

Don’t

• Consume salt and high-cholesterol (24 hours prior): May affect exam results
• Participate in any strenuous exercise (12 hours prior): Working out excessively may release protein into the urine and elevate liver function tests
• Drink alcoholic beverages (12 or more hours prior): Alcohol may cause dehydration and liver function test elevation
• Use nicotine or caffeine (at least 1 hour prior): Both are stimulants and may elevate heart rate.

o Black coffee is acceptable up to 1 hour before the exam
