Its sorta hard to explain, so sites say it should be a fasting
glucose test, when i asked two days b4 i had my
test, they told me i did not have to fast, and i had a burger 3 hours b4 my test, my levels was 138. A lot of women do fail the first one and pass the second one. Make sure you ask all the questions you need to no when you call the office or at your next appt.
