What does the BUN creatinine ratio tell you?
An increased ratio of BUN to creatinine may be due to conditions that cause a decrease in the flow of blood to the kidneys, such as congestive heart failure or dehydration. It may also be seen with high protein blood levels or from gastrointestinal bleeding.
What does BUN creatinine ratio of 30 mean?
The ratio is useful for the diagnosis of bleeding from the gastrointestinal (GI) tract in patients who do not present with overt vomiting of blood. In children, a BUN:Cr ratio of 30 or greater has a sensitivity of 68.8% and a specificity of 98% for upper gastrointestinal bleeding.
What foods to avoid if your creatinine is high?
Eating large amounts of protein, such as meat, fish, chicken, eggs, cheese, milk and yogurt can affect creatinine buildup, says Beaumont Hospital Kidney Centre. Therefore, those with high creatinine should seek dietary advice on how much protein to consume as too much protein can be detrimental.
What level of BUN creatinine ratio indicates kidney failure?
The normal range of blood urea nitrogen (BUN) is between 7 and 20 mg/dL or 2.5 and 7.1 mmol/L. There may be slight variations between labs. A decline in kidney function can cause an increase in BUN levels. There is no definite value of BUN that would diagnose kidney failure.
What does a BUN creatinine ratio of 36 mean?
In patients with acute GI bleeding, a BUN:creatinine ratio of 36 or greater suggests an upper GI bleeding site. In patients with GI bleeding and no renal disease, a BUN level over 40 mg/dL with a normal creatinine level suggests significant GI blood loss.
Can dehydration cause high BUN creatinine ratio?
Dehydration generally causes BUN levels to rise more than creatinine levels. This causes a high BUN-to-creatinine ratio. Kidney disease or blockage of the flow of urine from your kidney causes both BUN and creatinine levels to go up.
Is 25 high for BUN creatinine ratio?
The BUN/creatinine ratio is a good measurement of kidney and liver function. The normal adult range is 6 to 25, with 15.5 being the optimal value.
