A "good" eGFR (estimated Glomerular Filtration Rate) varies depending on your age, as kidney function naturally declines with age. Here's a general guide:
Your eGFR is a measure of how well your kidneys are filtering waste from your blood. It's a key indicator of kidney function. A higher eGFR generally means better kidney function.
While an eGFR of 90 or higher is generally considered normal, the acceptable range decreases with age. It's important to note that these are averages, and individual health conditions can affect what's considered "good" for you. Consult with your doctor for personalized advice.
Here's a table showing average eGFR values by age range:
| Age (range) | eGFR (average) mL/min/1.73 m2 |
|---|---|
| 20-29 years | 116 |
| 30-39 years | 107 |
| 40-49 years | 99 |
| 50-59 years | 93 |
Understanding eGFR and Kidney Disease:
- An eGFR below 60 mL/min/1.73 m2 may indicate kidney disease.
- An eGFR of 15 or lower indicates kidney failure, requiring dialysis or a kidney transplant.
Factors that Affect eGFR:
- Age: As you get older, your eGFR naturally decreases.
- Race: Some studies suggest that eGFR equations may need adjustments based on race.
- Sex: Men generally have slightly higher eGFRs than women.
- Health Conditions: Diabetes, high blood pressure, heart disease, and family history of kidney disease can impact your eGFR.
- Medications: Certain medications can affect kidney function.
What To Do if Your eGFR is Low:
If your eGFR is lower than expected for your age, your doctor will investigate the cause. They may recommend lifestyle changes, medications, or further testing. Regular monitoring of your eGFR is important, especially if you have risk factors for kidney disease.
