Glucose test?

Ka

All the posts I've been seeing about the glucose test say that they are usually 2 hours long and you have to fast beforehand. My doctor told me that mine will only be 1 hour and I don't have to fast before I come in. Does anyone elses doctors office do this? I'm afraid if I eat beforehand then it will throw off the test results. I'm going to try to avoid anything sugary and just eat some eggs and toast or something.
