It does this by measuring the amount of urea nitrogen in the blood. Normally, the kidneys filter out this waste, and urinating removes it from the body. BUN levels tend to increase when the kidneys or liver are damaged. Having too much urea nitrogen in the blood can be a sign of kidney or liver problems.

The normal range of BUN: creatinine ratio is in between and This ratio should not be more than in infants younger than 1 year. Elderly individuals have a slightly higher ratio of BUN: creatinine in comparison to young, healthy adults. The value is slightly greater in males in comparison to females.
An increased BUN: creatinine ratio indicates acute kidney failure, dehydration, mental shock, congestive heart failure or decreased flow of blood to the kidneys. On the contrary, a decreased ratio indicates malnutrition, SIADH syndrome of inappropriate antidiuretic hormone secretion , central nervous system diseases, cancer, muscle injuries such as rhabdomyolysis, liver diseases and bleeding in the respiratory or digestive tract.
Patients undergoing dialysis of the kidney have to regularly check creatinine and BUN levels. Kidney function can be reliably evaluated by this method. Copyright WWW.

Factors That Raise BUN Levels A diet high in protein Infection or fever, which increases the breakdown of proteins — a common feature of any illness Interval training or inflammation, which leads to breakdown of proteins from muscles Low consumption of water or dehydration.
BUN levels are increased as blood volume is decreased. BUN is elevated when activation of sympathetic arginine-vasopressin and angiotensin-aldosterone systems is inappropriately increased.
This is often seen in heart failure. Protein breakdown is also increased by cortisol hormone, thereby elevating BUN levels. Bleeding from the gut. When bleeding from upper GI tract occurs, that blood is digested to form protein. This protein is then metabolized to BUN by the liver.
