Use

Insulin is a peptide hormone that plays a critical role in regulating blood sugar levels. Serum insulin determinations are essential for patients with hypoglycemia symptoms, where an insulinoma is suspected. Insulin measurement is pivotal in diagnosing insulinoma by identifying elevated insulin levels during hypoglycemic episodes. Insulin levels are also useful for assessing insulin secretion capacity and evaluating insulin sensitivity. While fasting insulin is commonly measured to assess insulin resistance, the measurement isn't included in the American Diabetes Association's recommendations for diagnosing diabetes.
