Understand your BUN:Creatinine Ratio Blood Test Results…

This page helps you to understand blood test results for BUN:Creatinine Ratio and gives you the reference range to determine if your lab test results mean that you have high cholesterol, low cholesterol or normal cholesterol levels. 

We outline the risk factors associated with raised or low BUN:Creatinine Ratio levels.

Reference Ranges for BUN:Creatinine Ratio

The BUN:Creatinine ratio is the amount of Urea Nitrogen in the Blood divided by the amount of creatinine in the blood.

BUN and creatinine are the primary tests used to check how well the kidneys are able to filter waste products from your blood. The BUN-to-creatinine ratio generally provides more precise information about kidney function and its possible underlying cause compared with looking at creatinine or BUN in isolation [59].

An increased ratio may be due to a condition that causes a decrease in the flow of blood to the kidneys, such as congestive het disease or dehydration. It may also be seen with increased protein, from gastrointestinal bleeding, or increased protein in the diet. The ratio may be decreased with liver disease (due to decrease in the formation of urea) and malnutrition [59].
