To confirm adiabetesdiagnosis, a healthcare provider should conduct two different tests.
Your healthcare provider will explain the results and what they mean.
Perhaps you ate too many carbs at dinner or underestimated yourinsulinneeds.
Verywell
It makes sense to call your healthcare provider if you notice a pattern of elevated blood sugars.
This may be done to screen for diabetes or to monitor prediabetes or diabetes.
The American Diabetes Association (ADA) recommends screening for diabetes in all people age 35 years and older.
If the results are normal, it is repeated at least every three years.
It can also help people with diabetes to detect hyperglycemia.
A lab will then analyze the sample.
Prior to testing, you must avoid eating or drinking for at least eight hours.
Because of the need to fast, the test is usually done in the morning.
This can indicate a pattern of high morning blood sugar.
It is a good general measure of diabetes care and can help to determine hyperglycemia in people with diabetes.
It can also be used to diagnose diabetes.
you’re able to get an A1C reading through a regular blood draw.
No fasting is required during this test.
For a person without diabetes, a typical A1C level is about 5%.
A borderline A1C that indicates hyperglycemia or prediabetes falls within the range of 5.7% to 6.4%.
Lastly, the fructosamine test is used in gestational diabetes because changes can happen very quickly during pregnancy.
The test can be used to diagnose diabetes, gestational diabetes, or prediabetes.
The OGTT test is typically not indicated in diagnosing hyperglycemia in people who already have diabetes.
All pregnant women must undergo a glucose challenge between 24 to 28 weeks gestation.
Women with risk factors should be tested before 15 weeks of gestation.
Compared to the FBG test, the OGTT test is more time-consuming.
The test begins after an eight to 12-hour fast.
Next, blood is drawn to establish a fasting glucose level.
The test reveals how your body metabolized sugar and if it is clearing out of the blood efficiently.
The normal rate of glucose clearing depends on the amount of glucose ingested.
After fasting, the normal blood glucose rate is 60 to 100 mg/dL.
The good news is that detecting hyperglycemia early can increase your chance of preventing diabetes.
If you are pregnant and fail your first glucose tolerance, you’ll need to take another one.
Sometimes women don’t pass the first one but pass the second.
If blood sugars are very high at diagnosis, you may need to startoral medicationsor insulin.
Frequently Asked Questions
Your healthcare provider will set targets for you as an individual.
High blood sugar can be accurately diagnosed with blood tests.
However, the underlying cause of hyperglycemia might be misdiagnosed.
For some tests, yes.
Random blood glucose and A1C tests don’t require fasting.
