During my first pregnancy, I had a one-hour glucose screening test, which came back negative. This time, I'm seeing a different OB at a different practice, and she is sending me to get a two-hour glucose tolerance test, which requires fasting, instead of the one-hour test. She told me, "we do the 2-hour test," which I took to mean that it's her standard practice to send all of her patients to do the 2-hour test, but I could have misinterpreted. I didn't think to ask at the time, but now I'm curious why she's sending me for the glucose tolerance test instead of the screening/challenge test. I'm 32 years old and have an average BMI. Did anyone's doctor do the same? I'm not really worried about it, so I don't want to message my doctor unnecessarily. I'm just curious.
