About GFR
What is GFR? Glomerular Filtration Rate (GFR) estimates how well your kidneys filter waste from your blood. It’s a key indicator of kidney health.
How is it calculated? GFR is calculated using formulas like CKD-EPI, MDRD, or Cockcroft-Gault, which consider age, gender, serum creatinine, race, and sometimes weight.
Normal vs Abnormal Values: A GFR above 90 is normal. Values below 60 may indicate kidney disease. Values below 15 indicate kidney failure.
When to see a doctor? Consult a healthcare provider if your GFR is below 60 or if you have symptoms like swelling, fatigue, or changes in urination.
