About the GFR Calculator
The GFR Calculator estimates your glomerular filtration rate, a key measure of how well your kidneys filter blood. You enter a few lab and personal values and get an eGFR result in mL/min/1.73m², which reflects your current kidney function level.
The calculator uses the CKD-EPI equation, the standard method for estimating GFR from serum creatinine. It needs your serum creatinine value, age, and sex to produce the estimate. Because eGFR depends on accurate creatinine readings, use a lab report value rather than a guess. For decisions about kidney health, consider discussing your result with a healthcare professional.
- Enter your serum creatinine level from your blood test report.
- Add your age and select your sex.
- Read your estimated GFR value and compare it with typical kidney function ranges.
