CBC I am not a medical professional, but I survived cancer and need to keep a close eye on health. When blood comes out of my own body, I believe I should know how to read test results, understand values, and be prepared to ask questions! (BTW I don't mean self diagnosis thru the internet!)
The blood urea nitrogen or BUN is a blood test that measures the amount of urea nitrogen in the bloodstream. It reflects how well your kidneys are. When a person is dehydrated, false results might be obtained as BUN levels increase when blood is concentrated. Elevated BUN levels indicate dehydration, excessive protein intake and impaired renal function. Low BUN levels indicate over hydration, liver damage and malnutrition.
