I really feel you on the anxiety of waiting, especially when the results are unclear and no one has called yet. From what I understand, usually if only one value fails out of the full glucose tolerance test, it may not automatically be diagnosed as GD, but the guidelines can differ between hospitals and doctors. It would be good to call your gynae or the clinic to clarify, rather than waiting and worrying on your own. They can explain exactly what your results mean for your specific case and whether any follow-up is needed.
