Blood Urea Nitrogen (BUN) Body Fluids Test Overview

A blood urea nitrogen (BUN) body fluids test is used by doctors to check kidney function in patients. The goal of the test is to monitor the levels of urea and nitrogen in a patient’s blood and body fluids. Excessive levels of urea and nitrogen in the body indicates improper kidney function, which could lead to kidney failure resulting in serious medical complications.

Apart from blood, the peritoneal fluid in your body is also tested in a BUN test to ensure that the increased level of urea and nitrogen in the body are caused by kidney problems. Based on the blood urea nitrogen test results doctors can diagnose kidney problems and even determine the extent to which the conditions have progressed.

When Is Blood Urea Nitrogen (BUN) Body Fluids Test Prescribed?

A blood urea nitrogen (BUN) body fluids test is prescribed to patients who are suspected to have kidney disease. The purpose of the kidneys is to remove waste from the blood, when they fail to function properly, it leads to waste like urea building up in the blood. Here are some of the symptoms that correspond to high urea levels in the blood, which would warrant doctors to prescribe the BUN test.

Muscle cramps
Fatigue
Muscle soreness
Headaches
Restless leg
Seizures
Swelling in your arms, hands, legs, ankles, around your eyes, face, or abdomen
Tired all the time

Based on the symptoms and other underlying medical conditions, the blood urea nitrogen test can help doctors diagnose kidney problems and start appropriate treatment processes.

Components of Blood Urea Nitrogen (BUN) Body Fluids Test

For a BUN blood test, the only component of it is serum, which is tested to check your blood urea nitrogen levels. The normal level of urea nitrogen in serum is 9 mg/dL. Based on your test results doctors can prescribe further diagnostic tests or start treatment for kidney disease.

In terms of body fluids, the most commonly tested body fluid for a BUN blood test is peritoneal fluid. The normal level of urea nitrogen in peritoneal fluid is 1.0 mg/dL. The results of this urea nitrogen test can be used by doctors to further diagnose the extent of kidney disease and understand the effects of the condition on your health.

Procedure And Prerequisites

A blood urea nitrogen (BUN) body fluids test is performed using a technique known as abdominal tap. Doctors use a local anaesthetic to numb an area in your abdomen and use a long hollow needle to draw peritoneal fluid. The fluid is then sent for the blood urea nitrogen (BUN) body fluids test. There are no specific prerequisites patients need to follow for the blood urea nitrogen (BUN) body fluids test.
