Kidney Failure​

Chronic Kidney Disease (CKD)

Chronic Kidney Disease (CKD) means that your kidneys have been irreversibly damaged and the extent of the damage will only increase over time. There are five stages of CKD. CKD stage 5 refers to End Stage Renal Disease (ESRD), also known as kidney failure.

Stage 1
eGFR 90+
Stage 2
eGFR 60-89
Stage 3
3A eGFR 45-59
3B eGFR 30-44
Stage 4
eGFR 15-29
Stage 5
eGFR < 15 or on dialysis
Group Group1 Group2 Group3 Group4
Normal kidney function but urinalysis or structural abnormalities may indicate kidney disease Mildly reduced kidney function, and other findings (as for stage 1) point to kidney disease Moderately reduced kidney function Severely reduced kidney function Very severe or End Stage Renal Disease (ESRD)

The term estimated Glomerular Filtration Rate (eGFR) refers to the measurement of kidney function. A clinician or medical laboratory can estimate eGFR from the patient’s serum creatinine level, gender, age, weight and race. As CKD progresses, the eGFR declines and the patient will eventually need to undergo dialysis or transplant to survive.
