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.
A 2005 study in The Annals of Pharmacotherapy looked at the effect on cholesterol test results of a single six-ounce cup of coffee without sugar or cream, drunk one hour before testing. The good news is that the study found very small, clinically insignificant changes. The message then is that it is probably acceptable to have that single cup of black coffee, but if the results are borderline, I would consider repeating the test without the coffee. It may be prudent just to skip the cup for one day and not have the debate! Learn more in the Everyday Health High Cholesterol Center.
