How To Prepare – 1 hour test –
Eat a meal low in carbohydrates before this test. Example of foods to eat for breakfast would be eggs, cheese, bacon and or sausage. Avoid breads, cereals and fruit juices. Example of foods for lunch would be lettuce/salad with any kind of meat. Green beans, broccoli and any leafy vegetable. Avoid fried foods, no bread, soft drinks with sugar or sweet tea.1 1/2 – 2 hours after eating, drink the entire 59 gram glucola drink.Be at the office 30 minutes after finishing the cola. This is to insure that you are at the clinic on time for your blood work which will be drawn 1 hour after drinking the cola.When you check in at the fron desk, be sure and tell the receptionist what time you finished drinking the cola.

What should you not do before a pregnancy glucose test?
Do not eat or drink anything (other than sips of water) for 8 to 14 hours before your test. (You also cannot eat during the test.) You will be asked to drink a liquid that contains glucose (75 g). You will have blood drawn before you drink the liquid, and again 2 more times every 60 minutes after you drink it.

Can you trick the glucose test during pregnancy?
How do I know if I have gestational diabetes? There’s a test for that. – There aren’t any symptoms for gestational diabetes. All pregnant women are tested for the disease somewhere between 24-28 weeks. Here’s what you’ll do when you take the gestational diabetes test:
After one of your routine doctor’s appointments, you’ll be asked to visit the clinic laboratory. The lab tech will give you a sugary drink and after drinking it you’ll wait for one hour in the waiting room. This gives your body time to digest the drink so we can see how your body is handling glucose. When your hour is up, you’ll get your blood drawn and your glucose levels will be tested. Your doctor will share your results usually within 1-2 days.
If your glucose levels are high, don’t panic. This just means you’ll need to schedule another appointment at the lab to take a longer glucose test so we can take a closer look. Here’s what to expect:
First, you’ll need to fast for 12 hours before the test. Don’t try to fool the test. Altering your diet in anticipation for the test doesn’t work. You’ll come back to the lab and have your blood drawn once you arrive. Then, you’ll drink the sugary drink and wait for one hour. After that hour, you’ll get your blood drawn again. Then, you’ll go back to the waiting room and wait for a second hour. After the second hour, you’ll get your blood drawn again. Then you’ll wait for a third hour and get your blood drawn at the end of the third hour. Your doctor will share your results usually within 1-2 days.
If your glucose levels are still high after this longer glucose test, then you’ll be paired with a diabetes educator and dietitian to develop a plan to manage your gestational diabetes.

Will water mess up my glucose test?
Glucose Tolerance Test | Instructions For 3-hours This test is done to evaluate how your body is processing sugar and to determine if you have developed Gestational Diabetes (Diabetes of Pregnancy). The test requires a total of four blood draws. The first is done fasting (after you have had nothing to eat or drink for at least 8-12 hours prior—except water).
You should eat your normal diet prior to the day of testing. Do not eat, drink, smoke, or exercise for at least 8-12 hours before your first blood sample is taken. You may drink plain water but no other beverages. This test may take up to four hours to complete. Activity can interfere with the results so you will need to remain in the lab for the duration of the test. Consider bringing something to read or a project to work on while waiting. You may drink water so feel free to bring your own cup or water bottle. Once the test is completed, you may resume normal eating and drinking. You may be hungry once the test is finished, so you may want to bring along a light snack to eat before leaving or driving home.
Gestational Diabetes is typically diagnosed when two or more of the results are elevated. Your doctor may also use other criteria to make the diagnosis. Video Transcription:Hi, I’m Nicole, I’m a nurse here at Moreland OB-GYN and I‘m here to you about our two glucose tests that we do during pregnancy.
- These tests measure the pregnant women’s reaction to glucose and screen for gestational diabetes which is a condition when a woman that does not have diabetes ends up with elevated high glucose levels.
- Having elevated blood sugar during pregnancy can affect your baby and your delivery.
- Advanced maternal age, your activity level, being overweight, or having a family member with diabetes all are factors that can contribute to gestational diabetes.
First, I will explain the 1-hour glucose test, otherwise known as O’Sullivan Testing. You will be given a drink, like this, typically at your 24-week prenatal visit. You will be expected to drink the liquid prior to your next visit between 26 and 28 weeks of pregnancy.
You need to drink this within 5 minutes, and then you will have to have your blood drawn one hour from that time. What does the drink taste like? It’s very sweet so we recommend drinking it straight from the fridge so it’s nice and cold to help control that sweetness. It is recommended to avoid foods or snacks that are high in sugar prior to the test.
A normal or negative test result means you do not have gestational diabetes. However, an abnormal or positive test result means you are at risk for having gestational diabetes and we will need you to do the three-hour glucose test. So how does the three-hour test work? There are multiple blood draws for the three-hour glucose test, the first after fasting for 8-12 hours.
- Then you will be given a similar glucose liquid to drink and blood samples will be taken at 1, 2, and 3 hours after completing that drink.
- Because activity can interfere with the results, you will need to stay in the lab during the duration of the test, so we recommend bringing something to read, a project to work on, something to watch while you are waiting.
You may drink plain water during the test however no food can be consumed at the time. Bring a snack for after cause you may be quite hungry. Based on the results of this test and other criteria that your doctor uses, you will be given a diagnosis. If you’re positive after this test, your physician will provide you information and other resources on how to manage your gestational diabetes.
We hope this video gave you an overview of the testing performed to check for gestational diabetes. We have additional information on our website – Moreland o-b-g-n dot com, and if you still want more information, please ask your physician at your next visit. As always, it’s our job here at Moreland to lead women to better health.

Does drinking water help you pass glucose test?
Diabetes is a metabolic disorder that happens either because the body either produces insufficient amounts of insulin or doesn’t use insulin properly causing blood sugar (glucose) levels to rise (hyperglycemia). Drinking water before a fasting blood sugar test can actually decrease blood sugar levels, or at least prevent levels from getting too high.

- Drinking water before a fasting blood sugar test can actually decrease blood sugar levels, or at least prevent levels from getting too high.
Water allows more glucose to be flushed out of the blood. When you’re dehydrated, it means your overall blood volume is lower than normal, but your sugars will be the same. This means your blood is more concentrated (not diluted with water) and your blood sugar levels will be higher.

How do I avoid getting sick during glucose test?
Will the glucose tests make me feel sick? – Some moms-to-be feel nauseated after drinking the glucose solution, and a few even throw up. It may help to eat something a few hours before the screening test. If you vomit soon after you’ve gotten the drink down, you’ll have to come back on another day and repeat the test.

What does gestational diabetes make you feel like?
Gestational diabetes does not usually cause any symptoms. Most women only find out that they have it when they are tested for the condition. Gestational diabetes does not usually cause any symptoms. Most cases are only discovered when your blood sugar levels are tested during screening for gestational diabetes,
Your midwife will talk to you about the risk factors for gestational diabetes at your booking appointment, They will organise a pregnancy diabetes test if they think you’re at risk. “I wasn’t obviously skinny, but I wasn’t massively obese either I had no symptoms whatsoever. I had no expectation that the test would be anything other than a formality.” Beth Some women may develop symptoms if their blood glucose levels get high.
These include:
going to the toilet a lot, especially at night being really thirsty feeling more tired than usual losing weight without trying to general itching or thrush.
Some of these symptoms are common during pregnancy so may not be a sign of gestational diabetes. But it is best to find out as soon as possible. Tell your midwife or GP if you have any concerns. Try to remember that if you are diagnosed with gestational diabetes, careful management can reduce the risk of any complications.

What stage of pregnancy does gestational diabetes start?
Diagnosis – Gestational diabetes is diagnosed with a blood test, Your blood glucose level is measured after you drink a sweet beverage. If your blood sugar is too high, you have gestational diabetes. Sometimes one test is all that’s needed to make a definitive diagnosis.
- More often, an initial screening test is done, followed by a longer evaluation.
- Gestational diabetes usually does not occur until later in pregnancy, when the placenta is producing more of the hormones that interfere with the mother’s insulin.
- Screening for gestational diabetes usually takes place between weeks 24 to 28, but women at high risk are likely to be screened in the first trimester.

Will a banana affect a glucose test?
Testing Glucose Levels in Rotting Bananas – We love to hear from young customers working on classroom science experiments and science fair projects. Some of the project inquiries we receive are very interesting and unique. Below is an example of a science experiment one student was trying to perform using our Glucose Test strips,
For a project in one my classes I am trying to test the glucose levels in different types of bananas. Would it be possible to know if the test strips be suitable for differentiating the different glucose concentration in different types of rotting bananas?” – Susana This is an interesting question, Susana.
In theory, our Glucose test strips should be able to detect the glucose present. In practice, as with all scientific studies, the experimental protocol is critical. First, let us explain a bit about the glucose test strips, The glucose test strips were originally developed to test for glucose levels in urine for educational purposes (not for any medical applications). The strips employ an enzyme that is specific for glucose. Other sugars will not be detected by the strips. Other chemicals can interfere, one of the best (or worst) examples is Vitamin C. Foods with high Vitamin C may give a false positive. If the glucose being detected is in a water solution, the sample must sit for at least 3 hours before testing to allow for the mutarotation of the glucose molecule to occur.
- This mutarotation is necessary for the enzyme to work properly.
- In natural formats, the glucose has already undergone the proper rotation and can be detected without waiting.
- As for the range of the test strips, the color chart provided with the strips has a limit of 3000 mg/dl (30,000 mg/L) or 3%.
- If we understand correctly, ripe bananas can contain up to 15% sugar (with about 1/2 of that as glucose).
So, in theory, as the bananas ripen and the sugar content increases due to the conversion of the starch content to sugars, the test strips should be able to detect the glucose. The challenge of course is how the testing is to be done. If a ripe banana contains about 7.5% glucose, and if you were to take 40 grams of banana and emulsify it with 100 mL of distilled or deionized water, then allowed the water sample to sit for 3 hours, the glucose content should read at the high end of the chart (3%).
