Overview -

GFR Calculator

Glomerular filtration rate, or GFR, is the best indicator of your kidney function. Normal GFR depends on the body size, age, and gender, and it lowers with age.

With the help of a GFR calculator (also known as an estimated glomerular filtration rate calculator or eGFR calculator), it is possible to detect kidney disease in its early stages.

Keep reading to find out how is GFR calculated, the values of eGFR that are red flags, and a few frequently asked questions.

How to calculate

GFR?

There are several equations for calculating GFR, but the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) is the recommended and the most common method. It only requires results of one blood test—serum creatinine.

Here is the GFR calculation formula/equation for adults:

GFR = 141 × min (SCr/k, 1)α × max (SCr/k, 1) −1.209 × 0.993Age × 1.0189 (if women or else 1) × 1.159 (if black, 1 for others)

In which:

SCr indicates serum creatinine in µmol/L.

suitServices

K is 79.6 for men and 61.9 for women.

suitServices

α is −0.411 for men and −0.329 for women.

suitServices

Max indicates the maximum of Scr/k or 1.

suitServices

Min indicates the minimum of Scr/k or 1.

Please note: There are separate GFR calculators for adults and children.

GFR result interpretation

Now that you know how eGFR calculation is done, you may be wondering what the results imply. The table below shows typical eGFR values at various stages of kidney dysfunction based on data from the National Kidney Foundation.

eGFR [mL/min/1.73m²]
Kidney function
≥90
There is no or only mild/minor kidney damage
60-89
Kidney damage with mild or minor kidney function loss
45-59
Mild to moderate level of kidney function loss
30-44
Kidney function loss ranges from moderate to severe
15-29
Kidney function is severely impaired
<15
Kidney failure

A marginally lower eGFR than the normal range (60-89)does not necessarily indicate that you are at risk of kidney failure. To further clarify, eGFR declines with age, and the normal value of eGFR for people aged 70 years and over is only 75.

Only if your eGFR is less than 60 for three months consecutively (or if you experience any other concerning symptoms, such as elevated albumin levels in your urine), there is a possibility that you may have chronic kidney disease (CKD). You should make an appointment with your doctor for the right guidance in such a case.
