What are normal BUN ranges?
In general, around 6 to 24 mg/dL (2.1 to 8.5 mmol/L ) is considered normal. But normal ranges may vary, depending on the reference range used by the lab and your age.
Is BUN 28 high?
The normal BUN level is between about 7 and 21 milligrams per deciliter (mg/dL). Unless this level is greater than 60 mg/dL, it may not help your healthcare provider measure your kidney health. A better measure is the ratio of BUN to creatinine found in your blood.
What is a good BUN ratio?
The ideal ratio of BUN to creatinine falls between 10-to-1 and 20-to-1. Having a ratio above this range could mean you may not be getting enough blood flow to your kidneys, and could have conditions such as congestive heart failure, dehydration, or gastrointestinal bleeding.
What is a normal BUN and creatinine level?
The normal range for BUN/Creatinine ratio is anywhere between 5 – 20 mg/dL. BUN/Creatinine ratio increases with age, and with decreasing muscle mass [6].
What is the BUN level for kidney failure?
A GFR below 60 is a sign that the kidneys are not working properly. Once the GFR decreases below 15, one is at high risk for needing treatment for kidney failure, such as dialysis or a kidney transplant. Urea nitrogen comes from the breakdown of protein in the foods you eat. A normal BUN level is between 7 and 20.
What level of BUN requires dialysis?
A blood urea nitrogen (BUN) level of 75 mg/dL is a useful indicator for dialysis in asymptomatic patients, but one that is based on studies with limitations. Different parameters, including absolute and relative indicators, are needed.
What does BUN of 40 indicate?
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. A BUN level greater than 85 mg/dL with a normal creatinine level may indicate a loss of 2 or more units of blood into the GI tract.
