• It is ideal to be fasting for 10-12 hours before the blood draw. Do not eat or drink anything (except water) the morning of the appointment. You may also drink coffee, as long as it does not contain sweetener or cream. Participants should take their morning medications as usual. If a participant is not fasting, we will still perform the testing, but will make a note that they were not fasting when the sample was drawn. It will be up to the physician to interpret the results based on a non-fasting sample.
