Blood Urea Nitrogen (BUN) Analysis
Blood Urea Nitrogen (BUN) is a test that measures the amount of urea nitrogen in the blood, which is a waste product formed after the breakdown of proteins by the liver and removed from the body by the kidneys. The BUN test is commonly used to assess kidney function, the effectiveness of dialysis treatment, fluid balance, and help diagnose kidney disease.
Reference Range:
Normal Range: 7 to 20 milligrams per deciliter (mg/dL).

The BUN test is essential for assessing kidney function and detecting issues related to urea levels in the blood, making regular monitoring vital for those at risk of or experiencing kidney-related conditions, with treatment adjustments based on individual health profiles and medical history. If high BUN is due to kidney dysfunction, treatment may include medications to lower blood pressure and protect kidney function, dietary modifications, and dialysis for severe cases. Dehydration is managed by increasing fluid intake, while low BUN levels caused by liver disease or poor nutrition require treating the liver condition and improving dietary intake. Regular monitoring is often necessary for individuals at risk of or experiencing these conditions.
