eGFR
Also known as: Estimated Glomerular Filtration Rate
If creatinine is the raw reading, eGFR is the percentage score. It tells you roughly how much kidney filtering capacity you have. Mild dips can be temporary — trends matter.
What this test means
eGFR converts your creatinine, age, and sex into a single filtering score. It is the standard way kidney function stages are described.
Why it is done
It is done to stage chronic kidney disease, monitor kidney health in diabetes and hypertension, and adjust medicine doses safely.
Understanding your value
Values above 90 mL/min generally indicate normal filtration — high values are not a concern.
Lower values suggest reduced kidney filtering. Persistently below 60 for over three months suggests chronic kidney disease that needs care and monitoring.
90 or above is generally normal; 60–89 mildly reduced; below 60 needs medical follow-up. eGFR naturally declines slowly with age.
Consult your doctor if eGFR is below 60, falling on repeat tests, or if you have diabetes or blood pressure with any decline.
