Am 17 weeks pregnant. my gtt test value is 74mg. is this normal? i took it after breakfast. it seems very low. no other problems.

FS or blood draw?: If you are not having sx, i would not worry about it. I would worry only if you were on Insulin which could lead to dangerously low levels. A fasting of 74 is excellent. A 1-hour GGT seems too low unless it was a blood draw which was not spun down (whole blood can continue to metabolize glucose ; affect the value, making it lower). If you are light-headed or dizzy, d/w your doc or nutrionist.
