The most accurate way to know if your kidneys are okay is to get tested by a doctor, but here's how kidney function is typically assessed:
The primary method for determining kidney health is through a blood test measuring your Glomerular Filtration Rate (GFR). The GFR indicates how well your kidneys are filtering waste from your blood. This is estimated using a blood test that measures creatinine levels. Creatinine is a waste product produced by muscle tissue.
- Glomerular Filtration Rate (GFR): This is the best measure of kidney function.
- Creatinine: A waste product in your blood; levels are used to estimate GFR.
Understanding GFR Results
A normal GFR indicates healthy kidney function. According to the reference, a normal GFR result is higher than 90 mL/min/1.73 m2. If your GFR is lower than this, it could indicate kidney disease.
| GFR Level (mL/min/1.73 m2) | Interpretation |
|---|---|
| 90 or higher | Normal kidney function |
| Below 90 | Possible kidney disease |
Important Note: These levels can vary slightly depending on the lab and individual factors. It is crucial to discuss your results with your healthcare provider for accurate interpretation and personalized recommendations. They can consider other factors like age, sex, and ethnicity to give you the most accurate assessment.
