Kidney Bean eGFR Calculator
Enter your child's lab values to calculate their estimated kidney function (eGFR) using the Schwartz Bedside formula.
Results are shown through our Kidney Bean visual, designed with pediatric kidney patients and families to make lab numbers feel meaningful.
The Kidney Bean Visual was designed following published research from the HIVE Lab at Seattle Children's Research Institute, which found that pediatric kidney patients and families understand their health better through emotion-based visual analogies than through raw numbers.
