What is the blood nitrogen test?

Blood nitrogen test of urea, often called Bun test, is used to determine whether the kidneys and liver work appropriately. The test analyzes the nitrogen level in the blood. Nitrogen is produced by urea, a type of chemical waste made of broken proteins in the liver. An individual with elevated nitrogen urea nitrogen may have a kidney disorder, while lower levels may indicate the abnormality of the liver.

The kidneys are responsible for filtering of urea from the body. In general, this chemical leaves the liver and enters the kidneys, where it is excluded from the body by urination. The kidneys that work properly filter it effectively, but when there is a problem with the organs, urea is built in the bloodstream. The nitrogen nitrogen test will reflect an increase in nitrogen from excessive urea. The patient may be exhibitions such as frequent urination, pain on the sides, reduced urination or lower back pain. In people with kidney disease, the test may be carried out to detect the extent of kidney damage or in order to have established FUN treatmentgala. For example, individuals on dialysis can be performed frequent blood tests to measure the effectiveness of their treatment.

Creatinine levels in the blood can also be obtained during the nitrogen test in the blood. Creatinin, like urea, is a waste product that is usually filtered with healthy kidneys. For this reason, the presence of creatinine in the blood may also indicate the kidney problem. When nitrogen is performed at the same time nitrogen and creatinine test at the same time, the results will usually be compared for the ratio of the bunto-creatinin.

For the test, a blood sample is needed, which is usually considered painless, except for a smaller prick needle. As with any injection site, there is a minimal risk of infection, although this is not often the case. Small bruises may occur after the blood is sent. If the injection site begins to bleed quickly, the individual should put pressure in the place and seek immediate medical care.

paCaces are usually informed about the results of the nitrogen test as soon as the healthcare professional who ordered results. High nitrogen levels in urea may indicate a kidney problem, from infection to abnormal growth to disease. If the test reveals particularly low levels, it may be a problem with the liver. Medical providers usually treat the condition causing abnormal levels, although there are benign conditions that can cause nitrogen levels in both directions.
