How do I fast?

Prior to your test, you must not have anything to eat, drink or chew, for a minimum of 12 hours prior to the blood collection. This includes coffee, juice, tea, alcohol, chewing gum, candy or lozenge. You may drink water as usual. Note that there must be absolutely no additives to the water. Please check with your doctor about any medications that you are taking, and do not discontinue your medications unless authorized to do so by your doctor.
