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.
If your doctor did not tell you how long to fast, you should not eat or drink anything for approximately 12 hours prior to the test. Fasting means you should not eat or drinâ¦k any liquids except for water.. For further details please visit -- http://www.stjohn.org/Lab/FAQs/ You can also have plain black coffee.
