Have you ever failed a Gestiational Diabets test and NOT had it?

[mombojombo]

Every woman is tested and some fail.  Does it always mean you have gestational diabetes to fail the first test or do some fail and turn out not to have it?

I failed the one hour several times, but only had GD once.  I followed strict orders about carbs/food before the test.  I wasn't a heavy carb eater anyway, due to the fact that I had GD before, but I still failed the one hour.  Now, they just make me do the three hour right away, so I don't have to waste my time doing two tests.

I did.  I ate a peanut butter sandwich before the test.  Duh.  Failed it and had to do the 4 hour test and passed that one!
