Major clinical application of insulin is the diagnosis and management of diabetes mellitus. Due to absolute lack of insulin secretion, or relative lack of tissue glucose utilization disorder caused by elevated blood sugar, diabetes may be associated with severe complications, such as kidney failure, heart disease, nerve damage, blindness and gangrene. Severe hyperglycemic episodes can cause ketoacidosis and coma. Detection of insulin can be used to distinguish between type I and type II diabetes. For patients using insulin analog to treat diabetes, insulin is measured to determine the variety of formulation, and to assess the dosage use during the course of treatment. Since elevated insulin is sustained risk factor for heart attack, testing insulin levels in patients with diabetes provides tips for prevention of cardiovascular complications.
