Diabetes Screen: Glucose is the primary energy source for all body tissues. The sugars and carbohydrates you eat are ordinarily converted into glucose, which can be used to either produce immediate energy or be stored in the liver or as fat throughout the body.

Blood urea nitrogen is a waste product from protein breakdown in the liver. It is excreted by the kidneys. If kidney function is impaired, or if a person is dehydrated, the urea nitrogen level will increase. Internal blood loss, high protein diets and intense exercise can also cause a high urea nitrogen level. A low blood urea nitrogen level may be the result of liver disease, poor diet, pregnancy or drinking too much water.
