Thought I passed, but failed my 2 hr GTT

I’m super irritated. I did the 2 hour gtt because my lab doesn’t do the one hour. I had to drink 75g ( I understand for the one hour people drink 50g) My fasting blood sugar was 85, my one hour was 153, and my two hour was 100. Keep in mind I’m doing a 2hr gtt, having consumed 75g of sugar. My doctor says my one hour failed, even though everywhere I search regarding 2hr gtt, the parameters are failing if one hour > 180 and 2 hour >155. I’m so lost, and now I have to take my blood sugar 4 times a day. For reference my A1C is great 4.5
