Last week I had my second 1 hour glucose test, and the results are…I failed. The nurse called me yesterday, and told me to come in sometime this week for a 3 hour glucose test. Only problem is I have to be there between 8:30 and 9:00. That is quite early for someone who goes to sleep at 3 or 4 in the morning. If you are wondering what the 3 hour test is like, here is some information I found on Baby Center.
For three days before the test, you’ll be told to eat at least 150 grams of carbohydrate a day. If you eat a normal diet and have an extra piece of bread at each meal, you’ll likely be getting enough carbs. For eight to 14 hours before the test, you can’t eat or drink anything but sips of water (and you’re not supposed to smoke or exercise either), so you’ll want to schedule it for first thing in the morning.
When you arrive for the test, the technician will take a blood sample to measure your “fasting blood glucose level” and then ask you to drink either a more concentrated dose or a larger volume of the glucose solution. Then brace yourself for three more arm pricks, as your blood is tested every hour for the next three hours. The technician should alternate arms each time she draws your blood.
You’ll definitely need something to distract you this time, because you’ll have to stay seated in the waiting room between blood drawings. And bring something to eat right after your final blood sample is drawn because you’ll probably be starving.
If one of the readings is abnormal, you may have to take another test later in your pregnancy. Or your practitioner may ask you to make some changes in your diet and exercise routine. If two or more of your readings are abnormal, you’ll be diagnosed with gestational diabetes and you’ll need to talk to your practitioner about a treatment plan. This chart shows the levels that the American Diabetes Association considers abnormal at each interval of the test:
|Fasting||95 mg/dl or higher|
|One hour||180 mg/dl or higher|
|Two Hours||155 mg/dl or higher|
|Three hours||140 mg/dl or higher|
Pray all goes well.
