Blood Urea Nitrogen (BUN)

• The Blood Urea Nitrogen (BUN) Test is a diagnostic procedure that measures the level of urea nitrogen in the blood
• Urea nitrogen is a byproduct of protein metabolism in the liver and is excreted by the kidneys
• This Blood Urea Nitrogen (BUN) Test is essential for assessing kidney function and diagnosing potential renal issues

• Blood Urea Nitrogen (BUN) Test evaluate kidney function and health
• Blood Urea Nitrogen (BUN) Test diagnose and monitor kidney diseases
• Blood Urea Nitrogen (BUN) Test assesses the effectiveness of dialysis and other kidney treatments
• Determine the impact of medications on kidney function
• Blood Urea Nitrogen (BUN) Test aid in diagnosing other conditions that affect the kidneys, such as liver disease, heart failure, and dehydration

• A simple blood draw, usually from a vein in the arm
• Laboratory analysis to measure the concentration of urea nitrogen in the blood sample

• Interpretation of BUN test results involves comparing the measured levels against normal reference ranges, which can vary by age, sex, and laboratory methods
• Higher-than-normal BUN levels may indicate kidney dysfunction, dehydration, high protein intake, or other health conditions
• Lower-than-normal levels may suggest liver disease or malnutrition

• Normal Range: Typically 7 to 20 mg/dL, but this can vary
• High BUN Levels: May suggest kidney disease, dehydration, high protein diet, or heart failure
• Low BUN Levels: May indicate liver disease, malnutrition, or overhydration
