Insulin Fasting, Serum

Insulin is a hormone that regulates blood sugar levels. The fasting insulin test helps assess pancreatic function, detectInsulin resistance and diagnose Diabetes, .
Insulin function: Insulin is a hormone produced by the pancreas that helps the body use glucose (sugar) for energy. It lowers blood sugar levels by facilitating its uptake into cells. Without sufficient insulin, glucose builds up in the blood, leading to Diabetes, . Excess insulin may indicate Insulin Resistance.
Test significance: The fasting insulin test is used to assess pancreatic function, detectInsulin resistance and diagnose Diabetes, . Elevated insulin levels may indicate Insulin Resistance or preDiabetes, . Low insulin levels may suggest type 1 Diabetes, , where the body does not produce enough insulin.
Diseases: High insulin levels may be associated withInsulin resistance metabolic syndrome, or type 2 Diabetes, . Low insulin levels may indicate type 1 Diabetes, , where the pancreas does not produce enough insulin.
