Diabetes Tests: MedlinePlus Medical Test

What happens during a diabetes test?

There are several ways to screen for and diagnose diabetes. Most tests involve measuring glucose levels in the blood .
To get a blood sample, a health wish professional will take a blood sample distribution from a vein in your arm, using a small needle. After the needle is inserted, a small total of rake will be collected into a examination tube or phial. You may feel a short sting when the phonograph needle goes in or out. This normally takes less than five minutes.

The different types of glucose lineage tests include :

  • Blood glucose test, also known as fasting blood glucose. Before the test, you will need to fast (not eat or drink) for eight hours before the test. This test is often used as a screening test for diabetes. It may be repeated to confirm a diagnosis.
  • Oral glucose tolerance test (OGTT). This test also requires fasting before the test. When you arrive for your test, a blood sample will be taken. You will then drink a sugary liquid that contains glucose. About two hours later, another blood sample will be taken.
  • Random blood sugar. This test can be taken at any time. No fasting is required.
  • Hemoglobin A1c (HbA1c). This test measures the average amount of glucose attached to hemoglobin over the past 3 months. Hemoglobin is the part of your red blood cells that carries oxygen from your lungs to the rest of your body. No fasting is required for this test.

Glucose may besides be measured in urine. urine tests are not used to diagnose diabetes but may show if you are at hazard for getting the disease. If your glucose in urine levels are higher than normal, you will probably need a lineage trial to confirm the diagnosis.
