My doctor was very supportive of my decision. She said that there are other ways to test as well, that are less invasive and more accurate than than the glucose test, which has a fairly high false positive result. (Such as testing blood sugar for a week after meals, which I'd much rather do, as it's less invasive.)
I agree that measuring BS for a week is more accurate, but less invasive? In gtt they draw blood four times, in this method you need to prick your finger 4x7=28 times (you need fasting levels+after 3 meals). As to the amount of sugar in the test drink, it only feels so sweet, but in fact it is equal to a piece of cheesecake or less, so no danger at all. Also, not everybody has a meter and strips to measure sugar at home, and most insurance companies will not cover them without a confirmed diagnosis. Unfortunately
My doctor doesn't even do the one hour test, because she said it is too inaccurate. So in my case, I find the 3 hour test more invasive. (Fasting for a day, plus the drink, plus staying for 3 hours; If I fast for more than a four or five hours, I start gagging and will throw up... so that would NOT work for me. I wouldn't make it to the doctor! I was always gaggy when I was hungry pre-pregnancy, but now it's worse.) In that case, I'd rather prick my finger after every meal. So I guess less invasive really isn't the right term... it just would fit me better?
She gave me a printed list of risk factors, and said it was my decision if I felt I needed the test, because I hit none of them.
It reads that the risk factors are:
* A previous diagnosis of gestational diabetes or prediabetes
* A family history of diabetes
* Maternal age (under 25 is considered low-risk)
* Having an ethnic background
* Having a BMI over 25 (pre-pregnancy)
* Previous poor obstetric history
It's funny how it seems doctors are so different depending on where you go. If it weren't for this thread, I would have never known it was considered a "necessary" test. (She seemed to be steering me to not take the test.)
I'll do some more research on gestational diabetes and go from there.
