𝐞𝐆𝐅𝐑 – 𝐄𝐬𝐭𝐢𝐦𝐚𝐭𝐞𝐝 𝐆𝐥𝐨𝐦𝐞𝐫𝐮𝐥𝐚𝐫 𝐅𝐢𝐥𝐭𝐫𝐚𝐭𝐢𝐨𝐧 𝐑𝐚𝐭𝐞 is the best test to measure your level of kidney function and determine your stage of kidney disease. You can calculate it from the results of your blood creatinine, age, body size, and gender. If your GRF number is low, it may mean that your kidneys are not working as well as they should.
The earlier kidney disease is detected, the better the chance of slowing or stopping its progression.
