The test measures insulin hormone that regulates blood sugar level.

Insulin is a hormone made in your pancreas, a gland located behind your stomach. Insulin allows your body to use glucose for energy. Glucose is a type of sugar found in many carbohydrates.

Insulin also helps balance your blood glucose levels. When there’s too much glucose in your bloodstream, insulin tells your body to store the leftover glucose in your liver. The stored glucose isn’t released until your blood glucose levels decrease. Your blood glucose levels may decrease between meals or when your body is stressed or needs an extra boost of energy.
