Insulin Resistance Index Calculator

Formula

To calculate the insulin resistance index (IRI):

\[ IRI = \frac{I \times G}{22.5} \]

Where:

\( IRI \) is the insulin resistance index
\( I \) is the fasting insulin level (μU/mL)
\( G \) is the fasting glucose level (mg/dL)

Insulin Resistance Index Definition

The insulin resistance index, or HOMA-IR (Homeostatic Model Assessment of Insulin Resistance), is a tool used to estimate insulin resistance by utilizing fasting insulin and glucose levels. Insulin resistance is a condition where the body’s cells become less responsive to insulin, leading to elevated blood sugar levels. This index helps in assessing metabolic health and identifying individuals at risk of developing type 2 diabetes or cardiovascular diseases. It is a useful measure in both clinical and research settings.

Example Calculation 1

Let's assume the following values:

Fasting Insulin Level (I) = 15 μU/mL
Fasting Glucose Level (G) = 90 mg/dL

Using the formula:

\[ IRI = \frac{15 \times 90}{22.5} = 60.0000 \]

The insulin resistance index (IRI) is 60.0000.

Example Calculation 2

Let's assume the following values:

Fasting Insulin Level (I) = 10 μU/mL
Fasting Glucose Level (G) = 100 mg/dL

Using the formula:

\[ IRI = \frac{10 \times 100}{22.5} = 44.4444 \]

The insulin resistance index (IRI) is 44.4444.
