INSULIN FASTING

Elevated fasting insulin may occur when the body requires more insulin to maintain normal blood glucose, which can be associated with insulin resistance and metabolic conditions.

A low level may indicate reduced insulin production, particularly when blood glucose is elevated. Interpretation requires consideration of fasting glucose and other clinical findings.

Insulin resistance occurs when the body's cells respond less effectively to insulin. The pancreas may compensate by producing more insulin to maintain blood glucose levels.

It may provide information about insulin resistance, but fasting insulin alone is not a standard diagnostic test for prediabetes. Glucose and HbA1c are typically used for diagnosis.
