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.
When fasting for blood work can you drink decaf coffee? No. When fasting for any reason, the only thing that is permitted (and check with your doctor, as blood work is different than, say, surgery) is water, and only to take mediâ¦cation (again, if permitted by your doctor) A fasting status means nothing by mouth at all. This includes, of course, decaf coffee. If one doesn't fast the results of the lab tests could be completely wrong, and the doctor was under the impression that you were fasting. If you accidentally or for some other reason don't fast, MAKE SURE you alert your doctor right away.
