Population-based estimated glomerular filtration rate distribution

Percentile for this eGFR

Interpretation
Where these distributions come from

The percentile curves are drawn from the Stockholm CREAtinine Measurements (SCREAM) project, a health care utilization database covering the residents of the Stockholm region, Sweden.

Between 2006 and 2021 the cohort captured 1,179,501 adults aged 40 to 100 years, about 80% of the region's population in that age range, contributing 6,914,993 annual eGFR measurements from routine outpatient creatinine tests.

These are population-based distributions, not normative ones. Nobody was excluded for having diabetes, hypertension or cardiovascular disease.

The data describe the Stockholm region, and extrapolation to other regions or countries should be done with caution. Distributions below age 40 are not available: routine creatinine testing is too infrequent in younger adults to support them.

How to read the percentiles

In the study behind this tool, an eGFR below the 25th percentile for a person's age and sex was associated with an increased rate of kidney failure with replacement therapy, and both low and high percentiles were associated with increased mortality. This held even among people whose eGFR was above 60 mL/min/1.73m².

The estimating equations

The distribution changes with the equation, so compare a value against the curves for the equation it was calculated with.
