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.
The Urease Test Determines whether or not a microorganism can hydrolyze urea, a process that releases ammonia and produces a color change in pH indicators Urease hydrolyzes urea to form ammonia, water and CO2. Christensen urea agar is preferred In agar form, the slant is inoculated, not stabbed Phenol red is the pH indicator The resulting alkaline pH from hydrolysis of urea is indicated by a bright pink color
Creatinine is a waste product produced by muscle metabolism. Kidneys filter creatinine to be excreted through the urine and the renal function is reflected. Elevated levels indicate renal impairment. The opposite happens for urinary creatinine clearance; during renal impairment, urinary creatinine is extremely low. Measuring urinary creatinine clearance during unilateral kidney impairment is insignificant as the healthy kidney can still excrete creatinine through the urine.
Numerous conditions or factors can lower BUN and creatinine levels. According to the MedlinePlus website, blood urea nitrogen, or BUN, is a product that forms in your blood when protein breaks down. Tests can measure the amount of urea nitrogen in your blood. Creatinine is a breakdown product of creatine, which is an important component of your...
