What Is the Level of Creatinine and Urea in Acute Renal FailureAcute Renal Failure (ARF), also called Acute Kidney Injury (AKI) occurs when your kidneys suddenly become unable to filter products from your blood. There are some signs, such as elevated levels of creatinine blood urea nitrogen (BUN).

Creatinine and urea levels in blood in Acute Renal Failure

In Acute Renal Failure, the glomerular filtration rate (GFR) decreases over days to weeks. As a result, excretion of wastes such as creatinine and urea nitrogen.

Patients with acute renal failure are often asymptomatic, and the condition is diagnosed by observed elevations of blood urea nitrogen (BUN) and serum creatinine levels.

Most authorities define the condition as an acute increase of the serum creatinine level from baseline (i.e., an increase of at least 0.5 mg per dL or 44.2 umol/L). Complete renal shutdown is present when the serum creatinine level rises by at least 0.5 mg/dL per day and the urine output is less than 400 mL per day (oliguria).

Normal creatinine and BUN levels

Serum creatinine: 0.6-1.2mg/dl for men and 0.5-1.1mg/dl for women

BUN level: 5-20mg/dl for adults

In general, when creatine is higher than 5.0mg/dl, it means Kidney Failure. There is not definite boundary of Acute Kidney Failure, you should consult your doctors. Or you can send you test report to for suggestions.
