United States Embassy Pristina Security Message for U.S. Citizens: Heightened Caution During Religio. Senator John McCainâs Remarks to the Assembly of Kosovo. Thank you, Mister Speaker, Mister Prime Minister, and dear friends for that kind reception and for the honor of addressing this Assembly.
If you drink black coffee, with no additives, you can still have fasting labs done. However, coffee will increase your blood pressure and affect some tests .... especially a CRP. Your paying for these tests. I would recommend no coffee 10-12 hours prior if your not sure. The best method is to call the laboratory.
Unless you drink a great deal of caffeine, one cup less a day, with the day before the fast being caffeine free, will usually do it. Using decaffeinated coffee during this period may help you fool your system. Caffeine withdrawal symptoms are less of a problem when you are eating and drinking than when fasting.hough you should drink a lot before a fast, you do not need to stuff yourself with food. Eat a normal meal but emphasize carbohydrates like potato or noodle dishes, not proteins or fats. Carbohydrates bond with water which your body can drink when it needs to during your fast. Proteins do not.
