Understand your eGFR Blood Test Results…

This page helps you to understand blood test results for eGFR and gives you the reference range to determine if your lab test results mean that you have high, low or normal eGFR levels. 

We outline the risk factors associated with raised eGFR levels.

Reference Ranges for eGFR:

Measurement unit Metric Optimal Borderline Risk
US Conventional Units ml/min/1.73 m2 >=90 60-89 <=59
Standard International Units ml/min/1.73 m2 >=90 60-89 <=59

What is eGFR

Glomerular filtration rate (GFR) is a measure of the function of the kidneys. This test measures the level of creatinine in the blood and uses the result in a formula to calculate a number that reflects how well the kidneys are functioning, called the estimated GFR or eGFR.

The estimated glomerular filtration rate (eGFR) is used to screen for and detect early kidney damage, to help diagnose chronic kidney disease, and to monitor kidney status. It is a calculation based on the results of the blood creatinine test along with other variables such as age, sex, and race [54].

Function of eGFR

eGFR is often used to monitor people with known kidney disease and those with conditions such as diabetes and high blood pressure (hypertension) that may lead to kidney damage.

Risk factors associated with eGFR

eGFR is considered the most effective way to measure changes in Kidney status and to identify Chronic kidney disease.   Chronic kidney disease can be seen with a variety of conditions, including diabetes and high blood pressure. Early detection of kidney dysfunction can help to minimize the damage. This is important as symptoms of kidney disease may not be noticeable until as much as 30-40% of kidney function is lost [55].

Notable variations by eGFR

Variables such as age, sex, and race affect the eGFR and should be factored into the equation used to produce the result for each individual [56].

Diet to improve eGFR

Potassium is a mineral found in almost all foods. Your body needs some potassium to make your muscles work, but too much potassium can be dangerous. When your kidneys are not working well, your potassium level may be too high or too low. Having too much or too little potassium can cause muscle cramps, problems with the way your heart beats and muscle weakness.
