Accuracy of freely available online GFR calculators using the CKD-EPI equation.

ABSTRACT:

Purpose

Estimated glomerular filtration rate (eGFR) as calculated by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation is used for detection of chronic kidney disease and drug dose adjustment. The purpose of the present study was to investigate the accuracy of freely available eGFR online calculators.

Methods

All identified CKD-EPI online calculators were run with five reference cases differing in age, sex, serum creatinine, and ethnicity. Conversion from eGFR_indexed (unit ml/min per 1.73 m²) to eGFR_non-indexed (unit ml/min) and creatinine unit from milligramme/decilitre to micromole/litre was checked, if available.

Results

Only 36 of 47 calculators (76.6%) produced accurate eGFR results for all reference cases.
