Overview
Chronic renal failure (CRF), also known as chronic kidney failure (CKF) or chronic kidney disease (CKD), or chronic renal insufficiency (CRI) is a slowly progressive loss of renal function over a period of months or years defined as an abnormally low glomerular filtration rate. The glomerular filtration rate is usually determined indirectly by the creatinine level in blood serum.
CRF that leads to severe illness and requires some form of renal replacement therapy (such as dialysis) is called end-stage renal disease (ESRD).
