iGFR - The MDRD GFR

programmed by Stephen Z Fadem

Serum creatinine
mg/dL μmol/L

Creatinine methods recalibrated to be traceable to IDMS. (What is this?)
Age years
Race African American All other races*
Gender Male Female

GFR Value:??? mL/min/1.73 m2

Check if kidney damage for at least three months

*All ethnic groups other than African American
NOTE: The estimated GFR values above 60 mL/min/1.73 m2 should be interpreted as "above 60 mL/min/1.73 m2," not an exact number.
