BUN blood test

BUN blood test

BUN (Blood Urea Nitrogen) blood test indicates the functioning of the kidneys. It is also done to check for efficiency of dialysis. BUN blood test measures the levels of urea nitrogen in the blood. BUN blood test results can be compared with creatinine test to check for dehydration. BUN - creatinine ratio can throw light on kidney functioning. Normal BUN blood levels are 7 - 20 mg/dl. Abnormal levels of BUN are usually indicative of renal failure or bleeding into the stomach or intestines. High levels of BUN in the blood can mean congestive heart failure, gastrointestinal bleeding, urinary tract obstruction or myocardial infarction. Lower levels of BUN in the blood may suggest malnutrition or liver failure. Some women notice decrease in BUN level in the third trimester of pregnancy.

Dialysis

Dialysis is a procedure that replaces the work of your kidneys, if your kidneys have failed and are not able to clean the blood. The dialyis procedures filter the blood of the toxic wastes, excess salt and water. A patient with malfunctioning kidneys needs dialysis when the toxic wastes in the body build up and cause the person to become sick. The BUN blood test and creatinine levels are measured to indicate the functioning ability of the kidneys.

Hemodialysis: A dialysis machine is used to filter the blood. A special type of filter is used. The patient's blood passes through the dialysis membrane and the solution within the dialysis machine filter receives the waste matter. Hemodialysis requires stricter diet control and fluid control.

Peritoneal dialysis: The peritoneal membrane lining the abdomen is used to filter the blood. A plastic tube (dialysis catheter) is placed in the abdominal cavity to remove waste products and fluid. The major problem with peritoneal dialysis is infection due to the plastic tube that can work as a potential entry point for bacteria into the body.

Complications that can arise from dialysis procedure are anemia, high blood pressure, pericarditis, high potassium levels, bone disease, infection and sleep disorders.

CMP blood test

A CMP (Comprehensive Metabolic Panel) blood test is a set of specific tests that aid in providing a physician with vital information on the status of a patient's liver, kidneys, blood sugar, blood proteins and electrolyte balance. Often a CMP blood test is part of a yearly examination. The CMP blood test encompasses:

  • BUN blood test
