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 from fasting blood glucose and insulin levels.
The calculator uses the HOMA-IR formula:
Where:
Explanation: The formula calculates insulin resistance by assessing the relationship between fasting insulin and glucose levels.
Details: HOMA-IR is a valuable tool for assessing insulin resistance, which is associated with various metabolic disorders including type 2 diabetes, metabolic syndrome, and cardiovascular diseases.
Tips: Enter fasting insulin in μU/mL and fasting glucose in mg/dL. Both values must be 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 insulin resistance.
Q2: When should HOMA-IR be measured?
A: HOMA-IR should be calculated from fasting blood samples collected after an overnight fast of 8-12 hours.
Q3: Are there limitations to HOMA-IR?
A: While useful for population studies, HOMA-IR may not be as accurate as more direct measures of insulin sensitivity in clinical settings.
Q4: Can HOMA-IR be used for diagnosis?
A: HOMA-IR is primarily used as a screening tool and research instrument rather than a definitive diagnostic test.
Q5: How often should HOMA-IR be monitored?
A: Frequency depends on individual risk factors and clinical context, typically ranging from annually to every few years.
