A normal eGFR is 60 or more. If your eGFR is less than 60 for three months or more, your kidneys may not be working well. If you eGFR is below 15, you may need to start dialysis or have a kidney transplant. Use this scale to see what your eGFR may mean.

Stage 1 Stage 2 Stage 3 Stage 4 Stage 5

eGFR in normal range (greater than 90) with other signs of kidney damage, like protein in urine or physical damage to the kidneys

eGFR in normal range (60-89) with other signs of kidney damage, like protein in urine or physical damage to the kidneys

eGFR 30-59, moderate kidney damage

eGFR 15-29, severe kidney damage

eGFR less than 15, the kidneys are close to failure or have already failed
