eGFR calculator

eGFR stands for estimated Glomerular Filtration Rate. eGFR is calculated from blood test results using a formula that looks at the level of creatinine (a waste product) in your blood. Results consistently below 60mL/min/1.73m2 indicate chronic kidney disease. eGFR can also be calculated by using the eGFR calculator below.


*This calculator uses the CKD-EPI formula. Some pathology results may use an alternate formula, which will result in slightly different result. Please note the calculator is not valid for people under the age of 18.

If you're a health professional, referencing a patient's eGFR can be helpful in explaining what stage of kidney disease they're in. We've also listed some additional information to provide you with context, below.

If you're a patient or carer that would like to read about what eGFR means for your, please download our eGFR fact sheet.
