Oh I'm sorry that value showed up on Annie's blood work. The blood urea nitrogen (BUN) is a waste product produced by the liver from proteins from the diet, and is eliminated from the body by the kidneys. When it is increased, that is a sign of kidney disease. Hers is quite elevated, and I would discuss with the vet treatment options if they feel she has kidney disease.

Elevated BUN can be due to kidney disease (reduced eliminated) or increased production which can sometimes be due to a GI bleed. Your veterinarian will be able to determine the underlying cause of Annie's elevated BUN.
