The diagnosis of acute kidney failure is done based on an increase in serum creatinine and decrease in urine output. Diagnosis is done when there is a rise in serum creatinine by 0.3 mg/dl (26.5 μmol/l) or more in 48 hours to at least 1.5 times from the baseline within seven days .
Other tests such as blood tests, imaging tests and urine tests can help rule out acute kidney failure.
10 Common Bad Habits That Damage Your Kidneys
• Fluid therapy is given to acute kidney failure patients whose underlying cause is hypovolemia (loss of salt and water and decrease in blood volume). It is provided to restore the fluid balance and increase blood flow without causing any fluid overload .
• Dialysis is a treatment procedure that involves removing excess water and toxins from the blood out of the body and purifies the blood using a machine. Dialysis can help treat acute kidney failure, but it may lead to a long-term risk of chronic kidney disease .
• Maintain a healthy diet
• Monitor your blood pressure levels
• Practice exercise regularly
• Avoid having excess over-the-counter medications as they may hurt your kidneys and can cause acute kidney failure.

Acute kidney failure or acute renal failure (ARF) now called acute kidney injury (AKI) occurs when your kidneys stop working suddenly over a short period of time, usually in two days or less. Acute kidney failure is a serious syndrome and requires immediate treatment. It is more common in people who are hospitalised, especially people who are critically ill and needs extensive care .
What Causes Acute Kidney Failure?
Acute renal failure (acute kidney injury) is defined as a sudden decline in glomerular filtration rate leading to an increase in blood urea nitrogen and serum creatinine levels. According to the American Kidney Fund, acute kidney failure can occur due to the following reasons:
Diseases and conditions that reduce the blood flow to the kidneys can cause acute kidney failure, these include:
• Blood or fluid loss
• Blood pressure medications
• Heart disease 
• Heart attack
• Liver infection
• An infection 
• Severe allergic reaction (anaphylaxis)
• Severe burns
• Dehydration 
Certain conditions can damage the kidneys and cause acute kidney failure, these include:
• Renal ischaemia (deficiency of blood in one or both the kidneys 
• Sepsis 
• Glomerulonephritis (inflammation of the tiny filters in the kidneys)
• Some blood or blood vessel disorders
• Medications that directly damage the kidneys such as antibiotics and chemotherapy drugs.
Diseases and conditions causing a blockage in the urinary tract can cause acute kidney failure, these include:
• Kidney stones 
• Bladder problems
• Enlarged prostate
• Certain cancers
