And your BUN/creatinine ratio? Unless you enjoy reading Dictionary of Medical Terms, your routine lab results can seem downright cryptic. To help you decipher them, we asked Mark S. Lachs, M.D., author of Treat Me, Not My Age , and Marie A. Bernard, M.D., deputy director of the National Institute on Aging, to explain what all those numbers The BUN or urea nitrogen test is used to evaluate kidney function. The test measures levels of urea or nitrogen in your urine. Though Walk-In Lab’s Medical Director reviews all lab results, testing through Walk-In Lab does not replace the need for your primary care physician. Walk-In Lab testing is intended for information and education I have just received my lab report stating my Bun level is high at 29; and my BUN/Creatine Level is high at 29.

Increased blood urea nitrogen (BUN) may be due to prerenal causes (cardiac decompensation, water depletion due to decreased intake and excessive loss, increased protein catabolism, and high protein diet), renal causes (acute glomerulonephritis, chronic nephritis, polycystic kidney disease, nephrosclerosis, and tubular necrosis), and postrenal causes (eg, all types of obstruction of the urinary tract, such as stones, enlarged prostate gland, tumors). Understanding Your Results. Your result will be a number that measures how much BUN is in your blood. The range considered normal is between 7 to 20 milligrams per deciliter. (A milligram is a very tiny amount — more than 28,000 to an ounce, and a deciliter is equal to about 3.4 ounces). Urea, commonly referred to as blood urea nitrogen (BUN) when measured in the blood, is a product of protein metabolism.
BUN is considered a non-protein nitrogen We use cookies to enhance your experience on our website.By continuing to use our website, you are agreeing to our use of cookies.

Amanda Hawkes 2/12/16 MTEC Dr. Semler BUN Lab Report Date of the Lab February 8 th 2016 Test Name Liquid Urea Nitrogen (BUN) Test Summary Urea is hydrolyzed by urease to produce ammonia and carbon dioxide. The lab used to use Nessler’s reagent and Berthelot’s reaction in the past but it now uses Talke and Schubert’s test. Urea and creatinine are nitrogenous end products of metabolism. Urea is the primary metabolite derived from dietary protein and tissue protein turnover. Creatinine is the product of muscle creatine catabolism.
Both are relatively small molecules (60 and 113 daltons, respectively) that distribute throughout total body water. In Europe, the whole urea molecule is assayed, whereas in the United
