What are blood glucose tests used to diagnose?

Glucose testing is primarily done to diagnose or manage type 1 diabetes, type 2 diabetes, and gestational diabetes. Diabetes is a condition that causes your blood glucose levels to rise.

What is a Blood Glucose Test?

The amount of sugar in your blood is usually controlled by a hormone called insulin. But if you have diabetes, your body either doesn’t make enough insulin or the insulin produced doesn’t work properly. This causes sugar to build up in your blood.

If left untreated, chronically elevated levels of blood sugar can lead to other serious conditions including kidney disease, blindness, and heart disease.

In some cases, blood glucose testing may also be used to test for hypoglycemia. This condition occurs when the levels of glucose in your blood are too low.

Hypoglycemia can occur in people with diabetes if they take too much of their medication, like insulin, exercise more than usual, or skip a meal. Less commonly, hypoglycemia can be caused by other underlying conditions or medications. Very low blood sugar is considered a medical emergency.
