About This Tool

This comprehensive IGG calculator estimates glomerular filtration rate (GFR) using three established medical formulas: CKD-EPI (most accurate for normal to mildly reduced kidney function), MDRD (widely used in clinical practice), and Cockcroft-Gault (older but still referenced). The tool requires serum creatinine level (in mg/dL or μmol/L), age, gender, and race (African American or non-African American) to provide accurate GFR estimation. Results include the calculated GFR value, kidney function classification (normal, mild/moderate/severe reduction, kidney failure), and interpretation guidance. All calculations are performed client-side with no data sent to servers.

Frequently Asked Questions

Find Quick Answers

What is IGG (Glomerular Filtration Rate)?

IGG (Glomerular Filtration Rate) is the best measure of kidney function. It estimates how much blood passes through the glomeruli (tiny filters in the kidneys) each minute. Normal GFR is 90-120 mL/min/1.73m².

Which formula should I use?

CKD-EPI is recommended as it's more accurate at higher GFR levels. MDRD is widely used in clinical settings. Cockcroft-Gault is older but still referenced in medication dosing guidelines.

Why do I need to input race?

Some formulas include race adjustment because studies show African Americans may have higher muscle mass affecting creatinine levels. This adjustment provides more accurate GFR estimation.

What do the GFR classifications mean?

Normal: ≥90, Mild reduction: 60-89, Moderate reduction: 30-59, Severe reduction: 15-29, Kidney failure: <15. These classifications help determine chronic kidney disease stages.
