<p><b>Página nueva</b></p><div>==Background==<br />
*Blood urea nitrogen; byproduct of protein metabolism cleared by the kidneys<br />
<br />
==Normal Values==<br />
*Normal: 7-20 mg/dL<br />
<br />
==Interpretation==<br />
*Elevated BUN: renal failure, dehydration, GI bleeding (digested blood is a protein load), high-protein diet, catabolic states<br />
*BUN:creatinine ratio >20:1 suggests prerenal azotemia or upper GI bleeding<br />
*BUN:creatinine ratio <10:1 suggests liver disease, malnutrition, or rhabdomyolysis<br />
*BUN is less specific than creatinine for kidney function<br />
