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.
Drinking Coffee Before Blood Test Affect the Results. Drinking coffee before blood test can affect the results of tests that measure blood sugar and cholesterol levels. Coffee contains caffeine that is easily absorbed into the system at a fast rate. Caffeine can temporarily raise blood sugar levels resulting to an inaccurate fasting blood sugar (FBS) result. This happens as a result of caffeineâs stimulation of the pancreas to release insulin â hormone that regulates blood sugar level.
