This test measures the amount of insulin in your blood after you have not eaten for at least 8 hours. This test can help your doctor understand how your body is processing sugar and can help diagnose diabetes or other conditions related to insulin levels.

Key Purpose:

• Assess body’s insulin production and regulation
• Screen for insulin resistance
• Detect early signs of metabolic dysfunction
• Evaluate potential diabetes risk
• Role in the Body Critical Functions:
• Regulate blood sugar levels
• Transport glucose into cells
• Support metabolic processes
• Control energy storage and usage
• Normal Ranges Optimal Fasting Insulin Levels:
• Most experts recommend: 2-10 μU/mL
• Ideal range: 2-5 μU/mL
• Medscape reference: Under 25 μU/mL
• Test Limitations Potential Constraints:
• No universal consensus on exact reference ranges
• Results vary by individual
• Influenced by:
• Age
• Body composition
• Recent diet
• Stress levels
• Individual metabolic differences
• Low Results May Indicate Potential Conditions:
• Healthy insulin sensitivity
• Effective metabolic function
• Optimal glucose processing
• Low inflammation
• High Results May Suggest Potential Risks:
• Insulin resistance
• Prediabetes
• Increased cardiovascular disease risk
• Potential metabolic syndrome
• Early diabetes development

Always require professional medical interpretation for accurate diagnosis.
