What is GFR?

• The full form of GFR is ‘Glomerular Filtration Rate’
• It is a test used to measure the function of your kidneys, if the GFR decreases over a period of time; it may indicate CKD (Chronic Kidney Disease)
• It is a lengthy test usually hence, an estimation is employed from some easily available values like serum creatinine, age, etc
• Hence, the value obtained is called as eGFR (estimated Glomerular Filtration Rate)
• The adjoining calculator will help you calculate your eGFR based on your age, serum creatinine value and gender
• Categories of kidney disease based on eGFR:
  • GFR > 90 ml/min is considered normal
  • GFR: 60-89 ml/min is considered slightly decreased and hence is considered stage is 2 CKD
  • GFR: 45-59 ml/min is mild to moderately low and hence is considered stage 3A CKD
  • GFR: 30-44 ml/min is moderately to severely low and hence is considered stage 3B CKD
  • GFR: 15-29 ml/min is severely decreased and hence is considered stage 4 CKD
  • GFR < 15 ml/min is kidney failure and hence is considered stage 5 CKD
