eGFR (Estimated Glomerular Filtration Rate)
Calculated estimate of how well kidneys filter blood per minute. The best overall kidney function test.
Typical normal range
> 90 (normal) · 60–89 (mildly reduced) mL/min/1.73m²
If high ↑
Normal or above — sometimes seen with high muscle mass or hyperfiltration
If low ↓
CKD staging: 15–29 severely reduced, < 15 kidney failure
What is a normal eGFR level?
A typical reference range is > 90 (normal) · 60–89 (mildly reduced) mL/min/1.73m². Ranges vary between laboratories and can depend on age and sex, so compare your result with the range printed on your own report.
What does a high eGFR level mean?
Normal or above — sometimes seen with high muscle mass or hyperfiltration. A single result rarely gives a diagnosis on its own; your doctor will interpret it alongside your symptoms and other tests.
What does a low eGFR level mean?
CKD staging: 15–29 severely reduced, < 15 kidney failure. Your doctor will interpret it alongside your symptoms and other tests.
About the Metabolic Panel
A metabolic panel checks blood sugar, electrolytes and kidney function. It gives a broad picture of how your body handles energy and balances fluids.
