About GFR

Glomerular Filtration Rate (GFR) measures kidney function by estimating the rate of fluid filtration through the kidneys. This calculator uses serum creatinine, age, gender, race, and height to estimate GFR for adults (MDRD, CKD-EPI, Mayo Quadratic) and children (Schwartz). Consult a healthcare provider for accurate diagnosis.

GFR Tips

  • Blood Test: Ensure accurate serum creatinine measurement.
  • Consult Doctor: GFR results should be interpreted by a professional.
  • Monitor Regularly: Track GFR changes over time for kidney health.

GFR Tips

  • Use recent blood test results for accuracy.
  • GFR below 60 may indicate kidney issues.
  • Regular monitoring helps detect changes early.
