So confused (question about gestational diabetes)

[popcornbird]

Hi everyone,

I am about 28 weeks pregnant now, just started the third trimester, and I just had my glucose test yesterday morning. The doctor called with the results today.

Now...the reason I'm confused is this. I've been monitoring my sugar levels for the past two weeks on my dad's little blood sugar testing machine. For the past two weeks, on an empty stomach, it has consistantly been in the 80's or low 90's. The highest number I got on the machine was 138 so far, with a full tummy, regardless of what I ate that day, and how much sugar/carbs the food contained.

The doctor called and said that my blood sugar was 190, 1 hour after drinking the glucola, and she wanted it to be below 140.

I've been monitoring my sugar levels the whole day today. Morning, it was 92, half an hour after having a slice of whole wheat bread and string cheese. I had a bowl of rice and meat for lunch, and ate two chocolate See's Candies after that (wanted to test and see what happens when I eat sugar/carbs). 1 hour after eating, I tested, and my blood sugar was at 123. I ate some cereal about an hour later, and checked my blood sugar again, 1 hour after that. It was 135.

As far as I can see, those are completely normal levels. It seems very strange that it would jump to 190 in one test just for the doctor, when it has been at normal levels throughout the past two weeks.

My skin has been pretty itchy for the past few days, and I've been using a burt bee's body butter made of pure honey on my skin to soothe it. I did NOT wash my arm before going to the test, and am highly suspicious that the sugary cream on my arm may have come on the needle and elevated my sugar levels for the blood test. Do any of you think this is possible? Do you think I should request my doctor to re-test?

I'm pretty sure my dad's machine is accurate...he has diabetes and uses it everyday. Its results have always matched the results he gets at the doctor's office.

Has anyone else experienced anything like this? (Normal levels at home and high levels at the lab?)

The girl at the lab who took my blood was young and seemed to be really inexperienced. I don't think she cleaned the area properly, and she took the blood from a tiny vein instead of the main one, which caused the blood to come out really slow. It was strange. I wonder if that had something to do with the results. I'm a little concerned now, because my dr. had also ordered a few other tests, and if the results for this one were wrong (perhaps?), would that mean I need to retest for the other tests too?

Take a deep breath and tell your doctor just what you told us. I think being relaxed and not getting too worried is important right now.

How do you feel?

Was that the one hour test? If so, they usually will have you come back for a 3 hour test, where you drink the stuff and then they do a blood draw or finger stick every hour for 3 hours. I failed the 1 hour with both of my pregnancies, but I passed the 3 hour both times.

Yes, it was the one hour test. The nurse didn't mention the 3 hour test when she called me...just said the dr. wanted me to schedule an appointment with the nutritionist. Do you think they'll call me in for the 3 hour? I did call to ask if I could re-test, but my dr. is not in today. They said they'll have another dr. call and so far she never did. Oh well. Guess I'll just keep monitoring at home and report the numbers to the doctor whenever she gets back to me. How does the 3 hour test work?


I'm feeling pretty good, apart from some recent increase in heartburn.

prechrswife is right - there should have been a blood draw at 3 hours. It is normal for the one hour results to be elevated; the 3° test should be back too normal.

You cannot diagnose gestational diabetes on one solitary test - there needs to be a pattern.

What was the strength of the glucose you drank? The results will differ based on the dosage. The following numbers are from the NIH web site.

Normal blood values for a 75-gram oral glucose tolerance test used to check for type 2 diabetes:

* Fasting: 60 -100 mg/dL
* 1 hour: less than 200 mg/dL
* 2 hours: less than 140 mg/dL. Between 140 - 200 mg/dL is considered impaired glucose tolerance (sometimes called "prediabetes"). This group is at increased risk for developing diabetes. Greater than 200 mg/dL is a sign of diabetes mellitus.
------------------------------------------------


Normal blood values for a 50-gram oral glucose tolerance test used to screen for gestational diabetes:

* 1 hour: equal to or less than 140 mg/dL

Normal blood values for a 100-gram oral glucose tolerance test used to screen for gestational diabetes:

* Fasting: less than 95 mg/dL
* 1 hour: less than 180 mg/dL
* 2 hour: less than 155 mg/dL
* 3 hour: less than 140 mg/dL

Note: mg/dL = milligrams per deciliter

Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.

I would ask about the 3 hour. As soon as they called with the results on my 1 hour, they told me I needed to schedule the 3 hour. (And this was with 2 different doctor's offices/labs in 2 different states.)

Ask about getting an A1C test too, it measures what your levels have been approximately for the past 3 months. Its a much more accurate indicator of a problem than the other test according to my moms Dr.

*HUGS* to you!
