HOMA-IR Formula:
From: | To: |
HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) is a method used to quantify insulin resistance and beta-cell function. It's calculated from fasting blood glucose and insulin levels.
The calculator uses the HOMA-IR formula:
Where:
Explanation: The formula estimates insulin resistance by assessing the relationship between fasting glucose and insulin levels.
Details: HOMA-IR is a valuable tool for assessing insulin resistance, which is associated with type 2 diabetes, metabolic syndrome, and cardiovascular disease risk.
Tips: Enter fasting insulin in μU/mL and fasting glucose in mg/dL. Both values must be valid and greater than zero for accurate calculation.
Q1: What is a normal HOMA-IR value?
A: Typically, values below 1.0 indicate normal insulin sensitivity, while values above 2.0 suggest significant insulin resistance.
Q2: When should I test for HOMA-IR?
A: Testing is usually done after an overnight fast of 8-12 hours for accurate results.
Q3: Are there limitations to HOMA-IR?
A: While useful, HOMA-IR is an estimate and may not be as accurate as more complex tests like hyperinsulinemic-euglycemic clamp.
Q4: Can HOMA-IR diagnose diabetes?
A: HOMA-IR assesses insulin resistance but is not a diagnostic tool for diabetes. It should be used alongside other clinical assessments.
Q5: How often should HOMA-IR be measured?
A: Frequency depends on individual risk factors and should be determined by a healthcare provider.
