People working to control their diabetes will know that they need to check their blood sugar levels regularly, and they’ll likely also know that involves taking an actual small blood sample using a blood glucose meter. However, they may not know the name of the actual test or how they should be understanding and responding to those test results. For anyone looking to know what blood test checks diabetes, the answer is that diagnosing diabetes involves a fasting plasma glucose test, an oral glucose tolerance test,or a random plasma glucose test.
A fasting plasma glucose test measures your blood glucose 8 hours after you’ve eaten. An oral glucose tolerance test is done after you’ve gone at least 8 hours without eating and then two hours after you’ve had a glucose-containing beverage. A random plasma glucose tests your blood sugar in response to what you ate for your last meal. The first two tests can be used to diagnose pre-diabetes and diabetes, but the random plasma glucose test is only for a diabetes diagnosis.
An oral glucose tolerance test may also be used to diagnose gestational diabetes, which is when blood sugars become elevated as a result of a woman’s pregnancy.
Stay on Top of Your Blood Sugar Levels
Another consideration with being familiar with what blood test checks diabetes is to understand some of the particulars related to each of these tests. A fasting plasma glucose should be done in the morning, and for an effective oral glucose tolerance test, the drink you consume should contain 75 grams of glucose dissolved in water.
The last thing to mention here is that the standard hemoglobin A1C test used to measure blood sugar levels for diabetics is entirely different from any of the 3 tests mentioned here. An A1C test is one that diabetics will take on a regular basis in treatment of diabetes, but it is not a test for diagnosing diabetes in the first place.
What blood test check for diabetes? It will be a fasting plasma glucose test, an oral glucose tolerance test or a random plasma glucose test.If you have any reason to suspect you may be pre-diabetic then it is best to see your family physician as soon as possible. Working to treat diabetes is more effective the sooner you are able to have a diagnosis and begin taking steps to lower your blood sugar.
