Diabetes Tests

Diabetes Tests

Diabetes is a medical condition that affects the body’s ability to produce and use insulin correctly. As a result, it can cause high sugar levels in the body and a range of health complications. That is why it is important to make sure that diabetes is properly diagnosed and treated. Several tests are used to diagnose and monitor diabetes, including fasting blood glucose tests, oral glucose tolerance tests, and the HbA1C test.

Preparation for Diabetes Tests

Most diabetes tests do not require any special preparation. However, some tests, such as the oral glucose tolerance test, involve a special diet. Your doctor can provide more information on any required preparation.

Procedure for Diabetes Tests

Each test is slightly different. Your doctor will explain the step-by-step procedure for the test they have ordered. Generally, these tests involve either taking a sample of blood, or drinking a sugary solution.

Types of Diabetes Tests

  • Fasting Blood Glucose Test: A sample of blood is taken and the levels of glucose are tested. A level of over 126 mg/dL (milligrams per deciliter) suggests diabetes.
  • Oral Glucose Tolerance Test: A sugary solution is consumed, and blood is taken at intervals for several hours. A level of 200 mg/dL or more indicates diabetes.
  • HbA1C Test: This tests the level of glucose which has been attached to red blood cells over the previous two to three months. An HbA1C greater than 6.5% is used to diagnose diabetes.

Why undertake Diabetes Tests?

Diabetes can lead to a range of health complications if it is not managed. The tests used to diagnose and monitor diabetes provide information about the levels of glucose in the body to help doctors plan the treatment. Treatment usually involves lifestyle changes and medication.

When are Diabetes Tests undertaken?

Diabetes tests are usually undertaken when a doctor suspects that a patient may have the condition, or if they have a higher risk of diabetes, such as a family history of the condition, or if theyhave other risk factors. Patients with diabetes should also regularly undergo tests to monitor their diabetes levels.

Risks Associated with Diabetes Tests

Diabetes tests involve taking samples of blood, which will involve slight pain and discomfort. Some tests may also be associated with a range of side effects, such as nausea, vomiting, headaches, and dizziness, from consuming a high sugar solution.
