To check how well your kidneys are functioning, your NTKDA nephrologist will calculate the Glomerular Filtration Rate (GFR), which is derived from your blood creatinine, your age, race, gender, and other factors. The GFR determines the stage of kidney function, which are five.
Kidney damage with normal kidney function > 90 mL/ min
Kidney damage with mild loss of kidney function – 60 – 89 mL/ min
Mild to moderate loss of kidney function – 45 – 59 mL/ min
Moderate to severe loss of kidney function – 30 – 44 mL/ min
Severe loss of kidney function – 15 – 29 mL/ min
Kidney failure – < 15 mL/ min
