A fasting insulin of 11 μIU/mL does not indicate anything and suggests that pancreatic islet function may be normal. Insulin is the hormone that lowers blood sugar in the body, and fasting insulin is tested to detect pancreatic islet function and screen for diabetes. Under normal circumstances, the human fasting insulin is 10~20μIU/mL (the normal range of the assay should refer to the local hospital), fasting insulin is 11μIU/mL, which is within the normal range, and also refer to the blood glucose indicator, the normal range of fasting blood glucose is 3.9-6.1mmol/L. If fasting insulin and blood glucose are not high, it means that the basal secretion function of insulin is normal, and if there is no other symptom, there is no need for special treatment, and regular review can be done. Fasting insulin 11μIU/mL can be combined with other laboratory tests under the guidance of the doctor for comprehensive judgment.
