CARO insulin resistance index
The test is used to assess insulin resistance — a condition in which body cells reduce their insulin sensitivity. Calculated based on fasting glucose and insulin concentrations using the CARO formula. Helps detect early carbohydrate metabolism disorders and risks of type 2 diabetes, metabolic syndrome, and cardiovascular disease development.
What the test evaluates:
- Degree of cell insulin sensitivity
- Insulin resistance and diabetes development risk
- Pancreatic beta-cell function under elevated glucose load
Biomaterial: Venous blood (fasting)
- Draw blood fasting
- Exclude intense physical activity, stress, alcohol, caffeine 24 hours before
- Still water is permitted
Medications:
- Insulin, hypoglycemic drugs, glucocorticoids, hormonal agents may affect results
- Medication discontinuation only by physician agreement
Recommended for:
- Suspected insulin resistance or prediabetes
- Metabolic disorders and obesity
- PCOS and hormonal disorders
- Elevated cardiovascular disease risk
High CARO index: indicates pronounced insulin resistance, elevated diabetes and metabolic syndrome risk
Normal index: normal tissue insulin sensitivity
Combined assessment with glucose, insulin, HOMA-IR, and other metabolic markers recommended for accurate diagnosis.
