- Glucose, serum
Insulin, a hormone, controls the amount of sugar in your blood. However, if you have diabetes, your body either doesn’t make enough insulin or the insulin produced doesn’t work properly, resulting in sugar building up in your blood. Increased levels of blood sugar can lead to severe organ damage if left untreated. A glucose test is done to measure the amount of glucose in your blood.
Glucose testing is primarily done to check for type 1 diabetes, type 2 diabetes, and gestational diabetes. In some cases, blood glucose testing may also be used to test for hypoglycemia, a condition that occurs when the levels of glucose in your blood are too low.
The glucose test identifies abnormalities in the way your body handles glucose after a meal — often before your fasting blood glucose level becomes abnormal.
