A good kidney rate, also known as a good glomerular filtration rate (GFR), is typically 60 ml/min/1.73m2 or higher. This means your kidneys are filtering waste products from your blood at a healthy rate. A GFR below 60 ml/min/1.73m2 may indicate kidney disease.
Your GFR naturally declines as you age and lose muscle mass. For example, the average eGFR for someone in their 20s is around 116 ml/min/1.73m2, while it drops to 85 ml/min/1.73m2 for people in their 60s.
It's important to note that a low GFR doesn't always mean you have kidney disease. Other factors can influence your GFR, such as dehydration, certain medications, and recent muscle injury.
To accurately assess your kidney function, your doctor will consider your GFR along with other factors, such as your medical history, symptoms, and other blood test results.
