A good GFR (Glomerular Filtration Rate) typically ranges from 90 to 120 mL/min/1.73 m². A GFR in this range indicates normal kidney function. Values below this range could signal kidney disease or impairment.

FAQs & Answers

  1. What does a low GFR indicate? A low GFR may indicate kidney disease or impairment and should be evaluated by a healthcare professional.
  2. How is GFR measured? GFR can be estimated using blood tests that measure creatinine levels, or through more direct methods like a 24-hour urine test.
  3. What can affect GFR levels? Factors like age, sex, body size, and kidney function can affect GFR levels.
  4. Is a high GFR always good? While a high GFR generally indicates good kidney health, extremely high rates may require further evaluation.
