When you eat and drink normally, those foods and beverages are absorbed into your bloodstream.

Can you brush your teeth when your fasting for a blood test?
Fasting means that, with the exception of water, you refrain from eating or drinking for a minimum of 8 hours (10 to 12 hours is preferable) prior to the test. This means no coffee or tea beforehand, but taking your vitamins or medications is okay. Brushing your teeth or using mouthwash won’t influence the test.
Can you pee before a blood test?

How long will liver enzymes stay elevated after drinking?
Levels typically rise after heavy alcohol intake that has continued for several weeks (Allen et al. 1994). With 2–6 weeks of abstinence, levels generally decrease to within the normal reference range, with the half–life of GGT being 14–26 days. Laboratory tests for evaluating GGT are inexpensive and readily available.
What happens if you don’t fast before blood work?
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.
What is a normal blood sugar level after fasting for 12 hours?
A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it’s 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes.
Can I drink alcohol the night before a non fasting blood test?
Your healthcare provider will tell you when to stop eating and drinking before the test. Food and drink before the test may affect the results.
