Gfr Calculator FAQ

What does the Gfr Calculator calculate?
Estimates kidney function using the glomerular filtration rate from creatinine levels.
Should I use metric or imperial units?
Either — the calculator accepts both. Metric values (kg, cm) tend to have simpler conversion paths in the underlying formulas.
How accurate are these health estimates?
Results are based on validated formulas but cannot account for individual variation. They're useful as guidelines, not clinical measurements.
Is my data sent to a server?
No — calculations run directly in your browser. Your inputs are not stored or transmitted.
