eGFR Test

Is a lower eGFR always a sign of disease?

Not necessarily — eGFR naturally declines somewhat with normal aging, so your doctor considers your age, other kidney markers, and the trend over repeated tests rather than treating one borderline result as definitive.

How is eGFR used to stage kidney disease?

Chronic kidney disease is classified into five stages based on eGFR ranges, with lower values indicating more advanced disease and guiding decisions about monitoring frequency and treatment.

Can eGFR improve over time?

In cases of acute kidney injury from a reversible cause like dehydration or a short-term illness, eGFR can improve significantly once the underlying issue resolves; chronic kidney disease is more often managed to slow further decline.
