Test Parameters & Specifications
Sample Stability
- Insufficient sample volume
- Hemolyzed, icteric, or lipemic samples
- Improperly labeled or contaminated samples
- Sample not collected under fasting conditions
Understanding Your Results
Normal insulin sensitivity
Borderline insulin resistance; may indicate early risk
Significant insulin resistance; higher risk for type 2 diabetes
Consult a doctor if your HOMA-IR score is elevated (>2.0), or if you experience symptoms like persistent thirst, frequent urination, or unexplained weight loss. Also, seek medical advice if you have risk factors such as obesity or family history of diabetes.
Limitations
- ⚠Not a standalone diagnostic tool; must be correlated with clinical symptoms and other tests
- ⚠Reference ranges may vary by laboratory and population
- ⚠May not accurately reflect insulin resistance in all individuals, e.g., those with liver disease
Risks & Considerations
- ●Minor pain or bruising at the needle site
- ●Lightheadedness or dizziness
- ●Rare risk of infection or excessive bleeding
Interfering Factors
- ●Recent meals or non-fasting state
- ●Certain medications like corticosteroids or oral contraceptives
- ●Acute illness or stress
- ●Hemolyzed or lipemic samples
