An abbreviation of Estimated Glomerular Filtration Rate, egfr is a number that is obtained through a blood test conducted for the measurement of creatinine in the human blood. The basic purpose of estimating the glomerular filtration rate is to get to know that how well your kidneys are functioning. In order to detect any kidney damage or disease at an early stage, egfr is used. Although it is a very useful test but it is not valid and advisable for everyone. People with some already known kidney disease as well as diabetes and hypertension are advised to go for this test.
There is no extra testing required for egfr. It can be done at the same time when blood test is conducted for the measurement of creatinine. According to the research of National Kidney Foundation, egfr can be done automatically everytime when the creatinine test is being done. There is no specific time duration for taking this test; rather it can be done whenever the specialist or practitioner suggests the patient in order to get to know about the working condition of kidneys. According to the National Kidney Foundation, every person should know its egfr number as it helps to identify the sysmptoms and conditions of any upcoming kidney disease. The 90+ egfr shows that gfr is normal and the person has minimum amount of kidney damage which is nearly normal. The egfr ranging from 60 to 89 represents that gfr is mildly decreased and it should now be under observation for further symptoms. There will be a moderate decrease in gfr if the efgr lies in the range of 30-59. The rate below 15 will represent that there is extreme kidney failure and treatment on emergency basis is required.
