GFR Calculator

eGFR is an estimate, not a precise kidney-function measurement. A single value does not establish chronic kidney disease or a stage; trends and other information such as urine albumin-to-creatinine ratio are needed.

Do not directly use this result for medicine dosing, contrast, dialysis, or transplant decisions. Some medicines require another equation or removal of body-surface-area indexing; confirm with a clinician or pharmacist.
