What happens if you don’t fast before a blood test?
What happens if I don’t fast before a blood test? If you don’t fast before a test that requires it, the results may not be accurate. If you forget and eat or drink something, call your doctor or lab and ask if the test can still be done. They can then tell you if you need to reschedule your test.
Can you brush your teeth when your fasting for a blood test?
