Introduction

HOMA-IR and Estimated Average Glucose (eAG) are key diagnostic tools for evaluating kidney function and metabolic health. Comparing these markers helps healthcare providers determine the most appropriate test based on specific clinical conditions like renal filtration efficiency, nitrogen waste levels, or chronic kidney disease risk.

What Is HOMA-IR?

HOMA-IR measures how well your kidneys remove nitrogen-based waste (urea) from the blood. It’s often used to screen for dehydration, high protein intake, or impaired renal clearance.

What Is Estimated Average Glucose (eAG)?

Estimated Average Glucose (eAG) provides complementary insights into kidney performance, especially for estimating glomerular filtration rate or understanding renal stress through ratio-based or creatinine-based formulas.

When to Test

Your provider may recommend testing HOMA-IR and Estimated Average Glucose (eAG) if you're experiencing symptoms like swelling, fatigue, decreased urine output, or changes in hydration. They're also used for ongoing monitoring in patients with hypertension, diabetes, or known kidney conditions.

FAQs

Can I test for HOMA-IR and Estimated Average Glucose (eAG) together?
Yes, these tests are often bundled in comprehensive metabolic panels or renal panels.

Which is more accurate for early kidney damage?
Estimated Average Glucose (eAG) may offer better insight into glomerular filtration rate, a key indicator for early-stage renal disease.

What affects test accuracy?
Hydration status, medications, and recent diet can all impact values for both HOMA-IR and Estimated Average Glucose (eAG).
