Blood Urea Nitrogen

The big nitrogen (BUN) test is one of the routinely performed kidney function tests which involves measuring the concentration of urea nitrogen in the blood. It is a diagnosis of kidney efficiency which includes normal kidney function checking and is used for kidney diseases or monitoring. Because urea is a by-product of digestion of proteins this exam is also helpful in determining the amount of proteins you consume in addition to liver function.

This Test analyzes the concentration, in the serum, of the nitrogen component present in urea. The nitrogen component of urea is considered a waste product that originates from the metabolism of proteins in the liver It is then transported in the blood to the Kidneys where the nitrogen is filtered from the blood and excreted in urine. The aim of the test is to determine the ability of the kidneys to filter urea nitrogen out from blood and thus help in identifying if there are any problems affecting the kidney function.

A Blood Urea Nitrogen Test is usually recommended in cases where there are symptoms or risk factors of kidney problems. Some of the common scenarios include unexplained weakness, nausea, swelling of the legs and/or around the eyes, frequent urge or challenges to urinate, and so on. That test can also be utilized for the patients suffering from chronic kidney disease or those who have a high risk of developing kidney injury from hypertension, diabetes or other diseases. Also, it is a routine part of complete metabolic panels during regular health examinations.

The Blood Urea Nitrogen Test can be considered a safe low-risk procedure as it involves blood collection through a vein and its related effects may only include mild bruising or soreness at the puncture site. Nonetheless, some factors may hinder its efficacy. The BUN level can be dependent on certain factors such as dehydration, use of steroids, proteic diets, or liver damage that may lead to a misleading conclusion that is unrelated to the functioning of the kidneys. Because of this, it is commonly done together with other tests for reliable interpretation.

In blood urea nitrogen tests, the main parameter is the urea nitrogen level in the blood which is angles measured narrows. This test helps to check a number of health factors which include the following:.

• Kidney Function: How effectively kidney filters wastes.
• Dehydration: High result levels may translate into the person being dehydrated.
• Liver: Low levels can be interpreted as the liver having insufficient capacity to produce urea.
• Proteins: The amount of protein eaten and the efficiency of its metabolism.

The Blood Urea Nitrogen test is one of the most important for people who have signs or symptoms of kidney ailments such as fluid retention, unusual fatigue, and decreased urination or other such indicators. It is also indicated for individuals who suffer from chronic disorders such as hypertension or diabetes which may then affect the kidneys. This test may also be prescribed to people on high protein diets or patients with signs of liver dysfunction for thorough health evaluation and supervision.

The Blood Urea Nitrogen test should be taken as it has health benefits including identification of the early signs of kidney dysfunction which in turn will lower the risk of any kidney damage. Furthermore, it assists in tracking the state of the kidneys throughout the course of development of certain diseases that are present, avoiding complications that may arise if the kidney does not receive treatment. It helps other health evaluations especially those concerning peripheral blood filtration as well as hydration and nutritional status.

The Blood Urea Nitrogen Test can assist in diagnosing a range of conditions including:

• Chronic Kidney Disease
• Acute Kidney Injury
• Dehydration and overhydration
• Liver Disease
• Urinary Tract Obstructions

Precondition: Patients are required to refrain from eating and drinking for eight hours prior to the test appointment in order for conclusive results to be obtained. Along the lines, you should also inform your health care provider of any medication you are on, as some could alter the BUN levels.

Who is suitable: In general, the test is recommended to anyone suffering from any of the signs of kidney problems or for persons that are receiving normal checkups.

Steps on How to take the Test: A BUN test determined by a nurse the level of blood taken off from a patient’s arm and the normal process takes a couple of minutes after which the blood sample is sent to a laboratory for assessment.

Things to Note Before Taking the Test: To prevent skewing BUN levels, please abstain from high protein diet meals before the test. Drink water but if the health adviser asks you to fast, please follow through.
