CKD-EPI eGFR

eGFR is computed with the 2021 CKD-EPI creatinine equation from serum creatinine, age, and sex. Race is not in that equation. ACR and systolic pressure sit beside the result. In the first example the result is 86 mL/min/1.73 m².

The calculator is not a nephrology-clinic CKD stage and does not replace a laboratory report. eGFR is computed with the 2021 CKD-EPI creatinine equation from serum creatinine, age, and sex. Race is not in that equation. ACR and systolic pressure sit beside the result.

How it works

The calculator uses the numbers you enter. eGFR is computed with the 2021 CKD-EPI creatinine equation from serum creatinine, age, and sex. Race is not in that equation. ACR and systolic pressure sit beside the result. In the first example the result is 86 mL/min/1.73 m².

The five form fields are Serum creatinine, Age, Sex, Urine ACR if known, and Systolic blood pressure. EGFR means: This is the main result on this page. In the first example it is 86 mL/min/1.73 m². Serum creatinine means: The first form field. It enters the formula or sits beside the result. eGFR is computed with the 2021 CKD-EPI creatinine equation from serum creatinine, age, and sex. Race is not in that equation. ACR and systolic pressure sit beside the result. Age means: The second form field. The calculator is not a nephrology-clinic CKD stage and does not replace a laboratory report.

The second example gives 93 mL/min/1.73 m². The third example gives 46 mL/min/1.73 m². eGFR is computed with the 2021 CKD-EPI creatinine equation from serum creatinine, age, and sex. Race is not in that equation. ACR and systolic pressure sit beside the result. In the first example the result is 86 mL/min/1.73 m².

The calculator is not a nephrology-clinic CKD stage and does not replace a laboratory report.

Enter 1, 60, 1, 20, 128, then click Calculate. A comma in 12.5 is read the same way as a period. Fields on a 0-10 scale are notes and are not the primary result unless this page formula says so.
