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.
Can you have a cup of tea before a fasting blood test? You shouldn't: While the tea by itself is considered a liquid only, you may mix it with sweetner or cream. Further, there can be stimulating effects, which may have a change in your glucose or Insulin release. Just better to have water only.
