This test measures the level of insulin — the hormone responsible for moving glucose from the bloodstream into cells for energy.
Diagnostic Value: Insulin testing helps detect insulin resistance, type 2 diabetes, and certain metabolic or endocrine disorders.
Clinical Significance: High insulin levels can signal insulin resistance or early type 2 diabetes, while low levels may indicate type 1 diabetes or pancreatic dysfunction.
Symptom Correlation: Patients may report fatigue, hunger, weight changes, or difficulty managing blood sugar levels.
The Insulin test helps uncover metabolic imbalance before glucose levels become abnormal.
