how long to fast before glucose screening
The three hour test you need to fast for 12-14 hours prior because that test is fasting the lab needs a base fasting glucose to compare the rest of the blood after you drink the glucola.
Yes | No Thank you! The one hour glucose test you really dont need to fast because it is not a fasting test. After you drink the glucola you should not have anything to eat or drink, no gum,candy or mints. you also should not go smoke. Cigerattes have glucose in them too.
