UEA uria investigation with urea examination is investigated by urea concentration (UEA) or the nitrogen concentration at the Euphodian in the blood serum (blood-hour nitrogen bun). Urea is the final product in protein metabolism in the body, and it is produced in the liver of ammonia and is secreted by kidneys. The level of urea represents the amount of protein that a person consumes and sorted through the kidneys affects many factors at the level of urea, so it is considered a less accurate measure of creatinine to investigate kidney function. How to perform the investigation will take a blood sample out of a vein in the arm with a small needle, this procedure usually lasts less than five minutes, it is important to mention that you do not need special preparations before undergoing the investigation, but the specialist doctor will tell you if you have to stop taking any medication before it. General warnings The following complications can take place during the investigation: Excessive bleeding on the needle access site. Blood accumulation under the skin. Dizziness or faint if you see blood. Infection on the needle ground. Medicines affecting the result of the investigation include medication that can affect the level of urea in the blood, and this can accurately impair the investigation on the following: phenothiazine. Diuretics. Sulfa products. Morphine. Lithium. Salicilate. Chloraapampnicol. Natural levels analysis when urea should examine: 7 – 20 milligrams / dl. In some laboratories, nitrogenic acid blood (BUN) is investigated, and after examining it, we must double it to get urea values. For example, if the blood nitrogen’s blood examination is 10 mg per deset, it represents about 20 milligrams per urea. The possible results of this outbreak of natural pronunciation include the following: 1. The high levels are called the condition where urea levels are high in the serum with azotemia, which are three main types: the azotimi pre -kidney: which occurs when the fluid does not flow enough through the kidneys and urea in the blood. Agotemism is real: it occurs due to infection or disease, the most common cause of this type is acute tubular necrosis. Post -Renal nitromatic: It occurred due to the blockage of the urinary tract. Other reasons for the high level of urea: consume large amounts of protein. Bleeding in the digestive system. 2. Low levels. Low levels indicate that patients suffer from heavy liver and malnutrition.
