A normal Glomerular Filtration Rate (GFR) is generally considered to be 90 or higher. However, a GFR above 60 is also often considered within the normal range.
Here's a breakdown:
Understanding GFR
GFR, or Glomerular Filtration Rate, measures how well your kidneys are filtering blood. It's a key indicator of kidney function.
Normal GFR Ranges
| GFR Value | Interpretation |
|---|---|
| 90 or higher | Normal for most healthy people |
| Above 60 | Often considered within normal range |
| Below 60 | May indicate kidney disease |
Factors Affecting GFR
While the ranges above provide a general guideline, it's important to remember that "normal" can vary based on:
- Age: GFR naturally declines with age.
- Sex: Men generally have a slightly higher GFR than women.
- Body size: Larger individuals may have a higher GFR.
- Race/Ethnicity: Some studies suggest differences in GFR among different racial groups.
- Underlying health conditions: Conditions like diabetes and high blood pressure can impact GFR.
What to do if your GFR is below normal
If your GFR is below 60, it's important to consult with a healthcare professional to determine the cause and receive appropriate treatment. This might involve:
- Further testing to evaluate kidney function.
- Lifestyle changes, such as diet modification and exercise.
- Medications to manage underlying conditions like diabetes or high blood pressure.
