BUN (Blood Urea Nitrogen) Test

A Blood Urea Nitrogen (BUN) Test measures the amount of urea nitrogen in your blood. Urea nitrogen is a waste product formed in the liver when proteins are broken down and is excreted by the kidneys. This test is important for assessing kidney function and overall health.

Why is the BUN Test Important?

1. Kidney Function: Elevated BUN levels can indicate impaired kidney function or kidney disease.
2. Liver Health: Low BUN levels can sometimes indicate liver disease, as the liver plays a role in producing urea.
3. Hydration Status: High BUN levels can be a sign of dehydration.
4. Overall Health: Provides insight into how well your kidneys and liver are functioning, as well as your protein metabolism.

When Should You Get a BUN Test?

• Kidney Disease Symptoms: Symptoms such as fatigue, difficulty concentrating, poor appetite, and swelling in the feet or ankles.
• Liver Disease Symptoms: Symptoms such as jaundice, dark urine, and abdominal pain.
• Monitoring Kidney Function: For individuals with chronic kidney disease or those taking medications that affect the kidneys.
• Routine Health Check: As part of a comprehensive metabolic panel or basic metabolic panel.
