Understanding the GFR Formula: What is Glomerular Filtration Rate?
Learn about the GFR formula to assess kidney function and maintain renal health.
90 views
The formula for calculating GFR (glomerular filtration rate) is: GFR = (140 - age) × (weight in kg) × (0.85 if female) / (72 × serum creatinine in mg/dL). This formula, known as the Cockcroft-Gault equation, helps to estimate kidney function and assess renal health.
FAQs & Answers
- What does GFR stand for? GFR stands for glomerular filtration rate, a measure of how well your kidneys filter blood.
- Why is GFR important? GFR is crucial for assessing kidney function and diagnosing potential renal diseases.
- How is GFR calculated? GFR is calculated using the formula: GFR = (140 - age) × (weight in kg) × (0.85 if female) / (72 × serum creatinine in mg/dL).
- What does a low GFR indicate? A low GFR may indicate impaired kidney function and the need for further medical evaluation.
