eGFR
eGFR is an estimated glomerular filtration rate. It is calculated from your creatinine along with age and sex, and it estimates how much blood your kidneys filter each minute. It is the number most often used to describe kidney function.
Typical adult reference range
90 and above is usually reported as normal, and values are staged downward from there · mL/min/1.73m2
Ranges vary between laboratories and by age, sex and method. Always read your own result against the range printed on your own report.
What a high result can mean
A high or normal eGFR generally indicates the kidneys are filtering well. Unusually high values are occasionally seen in pregnancy or early diabetes.
What a low result can mean
A reduced eGFR means filtration is lower than expected. It falls gradually with age in most people. A persistent reduction over three months or more is how chronic kidney disease is defined, which is why repeat testing matters more than any single value.
What commonly affects this result
Everything that affects creatinine, plus the specific equation your laboratory uses, which is why values from different labs are not always directly comparable.
Questions worth asking your doctor
- Is this a one-off reading or a persistent change over months?
- Which of my medicines need adjusting at this level of kidney function?
- What should we be monitoring, and how often?

Reference ranges differ between laboratories, and results are only meaningful alongside your history, your symptoms and your other results. Always discuss your results with your doctor.
