Diagnosis*	Definition
Acute kidney injury	Rise in serum creatinine of ≥50% from baseline or a rise of serum creatinine by 0.3 mg/dl in 48h
Chronic kidney disease	Glomerular filtration rate of <60 ml/min for >3 months calculated using the MDRD formula
Acute-on-chronic kidney disease	Rise in serum creatinine of ≥50% from late baseline or a rise of serum creatinine by 0.3 mg/dl in 48h in a patient with cirrhosis whose glomerular filtration rate is <60 ml/min for >3 months calculated using the MDRD formula

*both the acute deterioration in renal function in the background chronic renal dysfunction can be functional or structural in nature
