INSULIN – FASTING

The fasting insulin test measures the level of insulin in the blood after a period of fasting, typically 8 to 12 hours. Insulin is a hormone produced by the pancreas that regulates blood sugar levels. This test is used to diagnose and monitor diabetes, insulin resistance, and metabolic syndrome. Elevated fasting insulin levels can indicate insulin resistance or hyperinsulinemia, while low levels suggest insulin deficiency. The fasting insulin test provides valuable information for assessing glucose metabolism, guiding treatment decisions, and managing conditions associated with abnormal insulin levels.
