Blood urea: Normal value

Blood Urea: normal value, clinical significance and methods of estimation Introduction: Urea is the chief nitrogenous waste formed during protein metabolism in man. It is devised principally from the amino groups of amino acids. Liver is the main organ where urea is synthesized by a process called ornithine cycle. After urea is formed in the liver, it passes into the blood and then excreted in the urine. The concentration of urea in blood depends upon the relationship between urea production ... Learn about the normal range of blood urea, including serum urea and urea creatinine levels. Discover the normal values, ranges in mg/dL, and the significance of blood urea tests. High blood urea can be an indication of underlying health conditions such as kidney disease, liver damage or heart failure. Blood tests are commonly used to diagnose high blood urea levels. The test measures two key components - Blood Urea Nitrogen (BUN) and Creatinine. A BUN test measures the amount of urea nitrogen in your blood, which helps assess your kidney and liver function. Learn what a high or low BUN level means, how to prepare for the test, and what other tests may be needed.
