This "test" is garbage. I wasn't told till way later, but the majority of women are sent for the 3hour test due to a false-positive for GD, meaning the first 1-hour test says they have GD but the 3 hour test says they don't. (Red is link)
It's REALLY important to know:
- Your test result numbers (different doctors have different cut offs)
- There is NO standard (as in the cut off numbers)
- This "test" is OPTIONAL
- This test is unreliable (you can take it every day for a week and get different results)
- That much sugar is impossible to consume on a daily basis and you need to really pig out on sugars to do so
- That much sugar is bad for you and baby
- The 3-hour test (starve yourself AND baby for 8-12 hours) is EXTREMELY dangerous and not good for either of you.
- ONLY if you meet the high risk group should you test (doctors don't follow this, but odds are you don't qualify to take this test)
If you're under 130 on the 1-hour test, you're fine.
If you meet the risk factors and/or do the 3 hour test just-in-case, eat HIGH CARB FOR 3 DAYS BEFORE THE TEST (no one told me this until way after).
Your 3 hour results should be:
At 0 hour (test before you drink glucose to make sure you're ok to do it): Between 60-90.
At 1 hour: Below 180
At 2 hours: Below 155
At 3 hours: Below 140
I "failed" my 1 hour by 10 points (Again, I didn't know about the 3-day carb loading) and did the 3 hour (I was told I had no choice but to take both the 1 hour and 3 hour....LIES I don't have any risk factors!).
I did the 3 hour and these were my results:
0 hour: 35
1 hour: 190
3 hour: 80
I asked my nephrologist (kidney doctor, I was born with Unilateral Renal Agenesis) about this "test" and he chewed me out saying no one should do this test unless symptoms of diabetes were present OR have risk factor(s). I have NEVER had any problems with sugar or diabetes-related and all of my tests have always come back normal or low (before, during and after pregnancy).
I was deemed "GD" but I knew it wasn't right. My midwife did random finger prick tests and I was always low or on the low side of normal. I ended up homebirthing a perfectly healthy baby who was well within normal range. And if you have untreated GD, the babies are almost always 9+pounds. My baby was 7 pounds even.
