Glucose Test

Myranda
So I'm supposed to go in and take my glucose test this week. A friend of mine told me I can't eat anything for 8hrs prior to the test. I don't remember my doctor telling me this so I don't know if it's true or not. I called my doctor but I am still waiting to hear back. I was wondering if you ladies could shed some light on this for me....can I eat before or not?
