- Gi Haemorrhage: The crack-up of rake in the digestive tract release protein, which the liver converts into urea.
Understanding Low BUN Levels
While eminent levels are more commonly discussed, a BUN on blood test result that is below the normal reach can also happen. Though less frequent, low levels are typically not a reason for panic but should nevertheless be investigated.
