What do you suggest for eating before glucose screening test?

Nothing: In general this would be a fasting blood test. This is not clearly defined, but lab professionals tell me that you should go at least 8 hours with nothing to eat or drink except water, plain tea or coffee and your medicines. There is also a test called an A1c, or average blood sugar that can be done after eating. For more info on proven screening tests, consider the Prevention Checklist app.
