Blood urea nitrogen(BUN) Index And Proteinuria Index For Quantum Magnetic Resonance Analyzer

Blood urea nitrogen(BUN) Index:

Blood urea nitrogen (BUN) measures the amount of urea nitrogen, a waste product of protein metabolism, in the blood. Urea is formed by the liver and carried by the blood to the kidneys for excretion.The amino acid deamination produces NH3 and C02, and which synthesis to urea in the liver.Per gram of protein metabolism of urea is 0.3g. The nitrogen have almost half content of 28/26 in the urea. Diseased or damaged kidneys cause an elevated BUN because the kidneys are less able to clear urea from the bloodstream. In conditions in which renal perfusion is decreased, such as hypovolemic shock or congestive heart failure, BUN levels rise.

Proteinuria Index:

There always have a certain amount of essential for human life activeites protein in the blood. A part of proteins will be filtered by sphere in the kidney and enter into the urine, but it may be absorbed in the renal tubules reback to the blood. Therefore, if the function of the kidneys is normal, the protein in the urine just has a little. However, when the kidneys and catherter leakage arises obstacles that will have a large amount of protein become to proteinuria. It's normal that have trace protein in the healthy people urine, and the normal range defined as negative. When the protein in urine up to more than 0.15g/24h, called proteinuria, and this can be as a positive qualitative urine.
