I Have The Results Of My Glucose Screening Test What’s The Normal Range For Blood Sugar
Different providers use different standards for determining whether your level is too high. Some will say that if your one-hour blood sugar level is 140 milligrams of glucose per deciliter of blood plasma or more, you need to have the glucose tolerance test. Others put the cutoff at 130 mg/dL to catch more women who may have gestational diabetes, even though there are likely to be more false positives this way.
If your blood glucose level for this screening is higher than 200 mg/dL, most providers will consider you diabetic and you won’t be required to take the glucose tolerance test.
But any score between 140 and 200 means that you’ll have to take the three-hour glucose tolerance test for a definite diagnosis.
Who Is At Risk
Risk factors for gestational diabetes include:
- having had gestational diabetes in an earlier pregnancy
- a family history of diabetes
- having obesity or other diabetes-related conditions
- being physically inactive
If a person gains more weight than is usual during pregnancy, this may be a sign of gestational diabetes, according to the
- attending more frequent screening and seeking medical help if glucose levels go up
- insulin use, in some cases
The healthcare provider will advise on each persons needs and treatment plan, as diabetes affects everyone differently.
What Is The Glucose Challenge Screening Test
No preparation is required prior to the test. During the test, the mother is asked to drink a sweet liquid and then will have blood drawn one hour from having the drink, as blood glucose levels normally peak within one hour. No fasting is required prior to this test.
The test evaluates how your body processes sugar. A high level in your blood may indicate your body is not processing sugar effectively . If the results of this screen are positive, the woman may have the Glucose Tolerance Test performed. It is important to note that not all women who test positive for the Glucose Challenge Screening test are found to have diabetes upon further diagnosis.
Who Is Most At Risk For Developing Diabetes
The following categories of people are considered “high-risk” candidates for developing diabetes:
- Individuals who have overweight or obesity.
- Individuals who are 45 years of age or older.
- Individuals with first-degree relatives with diabetes .
- Individuals who are Black, Alaska Native, American Indian, Asia American, Hispanic/Latino, Native Hawaiian, Pacific Islanders.
- People who developed diabetes while they were pregnant or gave birth to large babies .
- Individuals with high blood pressure .
- Individuals with high-density lipoprotein below 25 mg/dl or triglyceride levels at or above 250 mg/dl.
- Individuals who have impaired fasting glucose or impaired glucose tolerance.
- Individuals who are physically inactive engaging in exercise less than three times a week.
- Individuals who have polycystic ovary syndrome, also called PCOS.
- Individuals who have acanthosis nigricans, which are dark, thick and velvety skin around your neck or armpits.
In addition to testing the above individuals at high risk, the American Diabetes Association also recommends screening all individuals age 45 and older.
Is There An Alternative Way To Test For Gestational Diabetes
Yes. If you do not want to drink the glucose solution for one reason or another, there is another way we can test you for gestational diabetes.
It would involve you actually checking your blood glucose through finger sticks four times a day for an entire week. This will give us a good idea of how your body processes the foods you eat.
Again, dont try to manipulate this test in any way. For example, dont try to eat really healthy for that week, then go back to eating your normal diet the subsequent week.
Just to be safe, your health care provider may have you check your finger sticks for 2 or more additional weeks just in case.

Why The Test Is Performed
This test checks for gestational diabetes. Most pregnant women have a glucose screening test between 24 and 28 weeks of pregnancy. The test may be done earlier if you have a high glucose level in your urine during your routine prenatal visits, or if you have a high risk for diabetes.
Women who have a low risk for diabetes may not have the screening test. To be low-risk, all of these statements must be true:
- You have never had a test that showed your blood glucose was higher than normal.
- Your ethnic group has a low risk for diabetes.
- You do not have any first-degree relatives with diabetes.
- You are younger than 25 years old and have a normal weight.
- You have not had any bad outcomes during an earlier pregnancy.
What Is The Glucose Tolerance Test Like Do I Have To Fast
Fast overnight: Typically youre instructed to eat a late meal the night before the test and then to eat or drink nothing after that, except for sips of water. The fasting period is usually 8 to 14 hours before the test, so youll want to schedule the test for first thing in the morning.
Heres what to expect at the lab:
- First blood draw: When you arrive for the test, a blood sample is taken to measure your fasting blood glucose level.
- An even sweeter drink: Next, youll drink either a more concentrated dose or a larger volume of glucose solution.
- Three more blood draws: Brace yourself for three more arm pricks, as your blood is tested every hour for the next three hours. The lab tech should alternate arms each time your blood is drawn.
Some tips to make your test more comfortable:
- Have someone drive you to and from the test in case you feel lightheaded or are low on energy due to fasting.
- Bring something to distract you, because you have to stay nearby when your blood is not being drawn.
- Bring something to eat right after the final blood sample is taken, because youll probably be starving.
Results: After the test, if one of the readings is abnormal, you may have to take another test later in your pregnancy. Or your provider may ask you to make some changes in your diet and exercise routine. See What is the treatment for gestational diabetes? below.

If your doctor thinks you have type 1 diabetes, your blood may also tested for autoantibodies that are often present in type 1 diabetes but not in type 2 diabetes. You may have your urine tested for ketones , which also indicate type 1 diabetes instead of type 2 diabetes.
Can You Decline The Glucose Test In Pregnancy
If you decline the glucose test, then we will need to check your blood sugar levels 4 times per day for at least 1 week.
This will require you to prick your finger when you wake up every morning and one hour after breakfast, lunch, & dinner.
This is an alternative way to screen for gestational diabetes.

How Can I Measure My Blood Sugar Levels
You can measure your blood glucose levels with a glucometer. First, you prick your finger with a small device called a lancet to get a drop of blood. Your blood goes on a test strip which you put into the glucometer. Then, the device tells you your blood sugar levels.
You can also use a continuous glucose monitoring device, which uses a sensor that’s placed under your skin to automatically check your levels every few minutes.
How Do I Pass My 1 Hour Glucose Test
There is no one-size-fits-all answer to this question, as the best way to pass your glucose test depends on your individual fitness level, health condition, and blood sugar levels. However, some tips on how to pass your glucose test include:
1. Make sure youre well-rested and motivated before your glucose test.
2. Drink plenty of fluids before your test, and avoid eating greasy or high-calorie foods.
3. Make sure you have a fasting blood sugar level of at least 110 mg/dL.
4. Eat a healthy breakfast, lunch and dinner to help your blood sugar levels stay stable.
5. Practice with a glucose test simulator before your test.

What Abnormal Results Mean
Abnormal blood values for a 3-hour 100-gram oral glucose tolerance test are:
- Fasting: greater than 95 mg/dL
- 1 hour: greater than 180 mg/dL
- 2 hour: greater than 155 mg/dL
- 3 hour: greater than 140 mg/dL
Abnormal blood values for a 2-hour 75-gram oral glucose tolerance test are:
- Fasting: greater than 92 mg/dL
- 1 hour: greater than 180 mg/dL
- 2 hour: greater than 153 mg/dL
If only one of your blood glucose results in the oral glucose tolerance test is higher than normal, your provider may simply suggest you change some of the foods you eat. Then, your provider may test you again after you have changed your diet.
If more than one of your blood glucose results is higher than normal, you have gestational diabetes.
How Is Gestational Diabetes Treated
If youre diagnosed with gestational diabetes, your treatment plan will depend on your blood sugar levels throughout the day.
In most cases, your doctor will advise you to test your blood sugar before and after meals, and manage your condition by eating a nutrient-rich diet and exercising regularly.
They may also prescribe insulin injections for you until you give birth. Ask your doctor about properly timing your insulin injections in relation to your meals and exercise to avoid low blood sugar.
Your doctor can also tell you what to do if your blood sugar levels fall too low or are consistently higher than they should be.
A balanced diet is key to properly managing gestational diabetes. In particular, people with gestational diabetes should pay special attention to their carbohydrate, protein, and fat intake.
Eating regularly as often as every 2 hours can also help you manage your blood sugar levels.

An OGTT can be used to effectively diagnose various types of diabetes, including prediabetes.
Its useful for confirming a diagnosis after an abnormal HbA1c test result. An A1C test is often part of routine blood tests, but its less sensitive than an OGTT. Because of this, an OGTT can help with making an official diagnosis.
This can alter the results, potentially leading to a misdiagnosis.
An OGTT is also time consuming. You may need to take off from work or school. Theres currently no alternative for the test, according to 2018 research.
An OGTT is considered to be a safe test.
Be sure to eat a meal the night before. This may help reduce discomfort caused by fasting.
For some people, drinking the concentrated glucose solution causes side effects such as:
Additional side effects, such as diarrhea and heart palpitations, are more likely to affect people whove had bariatric surgery.
Other OGTT risks are the same as getting your blood drawn for any reason:
- skin irritation from adhesive on a bandage
If you have any concerns, talk with a doctor before taking the test.
How To Prepare For The Glucose Challenge Screening Test
The good news is that you dont really need to do much of anything to get yourself ready for this glucose screening test. We want to see how your body responds naturally to glucose, so just eat what you would regularly eat or drink, advises Greves.
Pope echoes this recommendation, but stresses that having long-term healthy lifestyle habits can ultimately improve your chances of passing: There really is no preparation besides trying your best to always eat as healthy as you can, and exercise routinely. This helps with glucose metabolism.
Still, if youve been doing your own internet sleuthing to figure out what to eat before your glucose testor in the hopes of sourcing hacks to help you pass the testknow that any touted tips are unproven and ill-advised.

A Rationale For Omitting Two
Get rights and content Objective: In making decisions regarding initiation of insulin therapy in gestational diabetes, most maternal-fetal obstetricians rely more on elevated fasting glucose values than on elevated 2-hour postprandial levels. We sought to determine whether the latter test is necessary. Study Design: From the patients with gestational diabetes mellitus managed over a 17-month period at Grady Memorial Hospital, we retrospectively analyzed data to determine whether normal fasting plasma glucose values predict elevated 2-hour postprandial values and whether the latter predict adverse outcome. Results: From 194 patients with gestational diabetes mellitus, 546 paired fasting and 2-hour postprandial glucose values were recorded. Fasting levels were normal in 467 in those, 2-hour levels were < 120 mg/dl in 83% and < 140 in fully 96%. In 131 women with all fasting plasma glucose values normal, the birth weights and the rates of cesarean delivery, shoulder dystocia, and macrosomia were similar, regardless of whether 2-hour postprandial glucose values were> 120. The actual cost of the 546 2-hour postprandial glucose tests was nearly $10,000. Conclusion: For metabolic surveillance in gestational diabetes mellitus, the 2-hour postprandial glucose test seems unnecessary, provided fasting plasma glucose values remain normal.Continue reading > >
