| Blood Glucose Test : What is a blood glucose test? A blood glucose test measures the glucose levels in your blood. Glucose is a type of sugar. It is your body's main source of energy. It comes from the food you eat. A hormone called insulin helps move glucose from your bloodstream into your cells for use as energy. If you have too much or too little glucose in your blood, it may be a sign of a serious medical condition. High blood glucose levels (hyperglycemia) may be a sign of prediabetes or diabetes. Prediabetes is a condition in which your blood glucose levels are higher than what is healthy for you, but not high enough to be considered diabetes. If you have diabetes, your body can't make insulin or can't use it as well as it should, or both. Too much glucose stays in your blood and doesn't reach your cells. This can cause glucose levels to get too high. If blood glucose isn't controlled, it can lead to serious, long-term health conditions, such as heart disease and nerve problems. High blood glucose may also be caused by other conditions that can affect insulin or glucose levels in your blood, such as problems with your pancreas or adrenal glands, and side effects from certain medicines. Low blood glucose levels (hypoglycemia) is often caused by certain diabetes medicines for type 1 diabetes or type 2 diabetes, including insulin. In people without diabetes, low blood glucose is much less common. It may be caused by certain medicines and conditions, such as some kidney or liver diseases. Without treatment, severe low blood glucose can lead to major health problems, including seizures and brain damage. Several types of blood tests check blood glucose levels. Your health care provider will choose the test that's right for you.
