BUN (Blood Urea Nitrogen) Test
What is the blood urea nitrogen (BUN) test? A blood urea nitrogen (BUN) test measures the amount of urea nitrogen in your blood. Levels of urea nitrogen is one marker on how well your kidneys are working. This is a simple test done by drawing blood out of your body through a vein in your arm. Jan 25, · The blood urea nitrogen test, which is also called a BUN or serum BUN test, measures how much of the waste product you have in your blood. If .
Last reviewed by Editorial Team on February 27th, Both BUN and creatinine are filtered in the kidneys and excreted through urination and they are a perfect parameter for identifying the overall functions of the kidneys.

Understanding the difference between BUN and creatinine test and their relationship. The function of the kidneys is to filter the urea so that waste products will be removed from the body through urination. The liver continuously produces urea and so it is just normal to have a small amount of urea in the blood. If the urea in the blood is abnormally high, it is an indicator that the what does dpdt switch stand for are not functioning well.
There could be something wrong with your kidneys that need to be addressed properly and timely. A creatinine is a molecule produced by muscle metabolism. It is transported through the bloodstream and filtered in the kidneys and excreted through the urine. The muscle mass of a person defines the rate of creatinine formation.
Ideally, the level of creatinine remains constant throughout the day. If the level how to increase strength in hands creatinine is high, then it indicates that there is something wrong with your kidneys. Picture 2: BUN and creatinine ratio is measured using the above formula. This is to find out the functions and overall condition of the liver and kidneys.
It is used by the doctor in formulating an accurate diagnosis of health problems that have something to do with the kidneys. Other reasons for taking BUN to creatinine ratio test include the following:.
Your protein intake can significantly affect the test result. A high protein intake may cause an abnormally high level of BUN.
On the other hand, a low protein intake may lead to an abnormally low level of BUN. If you are going to undertake a BUN creatinine ratio test, make sure that you consume a normal amount of protein and that you are properly hydrated.
That way, you will be able to come up with an accurate BUN creatinine ratio test result. The result can also be affected by pregnancy. Image 4: BUN and creatinine are two parameters used to detect the condition of the kidneys. The procedure is performed by a lab technician. A blood is drawn from your upper arm using a sterile needle.
The entire process would take around 5 to 10 minutes depending on the visibility of your vein. The ideal ratio is between and If the result is higher than the numbers mentioned, it indicates that there is a high level of BUN in the blood. It is linked with kidney-related diseases or decreased flow of blood to the kidneys secondary to dehydration or congestive heart failure.
If the result is below the normal ratio, then it could indicate malnutrition or liver-related diseases. The BUN and creatinine are both end products of metabolism. The BUN and creatinine are waste products that need to be filtered by the kidneys and excreted through urination.
A small amount of BUN and creatinine may be present in the blood and are just normal. However, if the ratios are too high or too low, it could signal that there is something wrong in your kidneys and liver. Your Name. Go search.

Note that each number in parentheses [1, 2, 3, etc. BUN blood urea nitrogen and creatinine are two blood tests that can reveal a lot about your metabolism, kidney, liver, and overall health. BUN blood urea nitrogen and creatinine are two lab tests that are often ordered as part of a comprehensive metabolic panel.
Your doctor may order this panel to get an idea of your overall health and metabolism. BUN measures the amount of urea in your blood. Urea is a waste product made in the liver as the body processes protein. This protein is mostly derived from the diet, but it can also result from tissue protein turnover [ 1 , 2 , 3 ]. Urea is removed by the kidneys, but the rate of removal depends on the needs of the body. The kidneys can return different amounts of urea into the bloodstream depending on factors such as hydration and blood pressure.
High urea is an important marker of kidney dysfunction as well [ 1 , 2 , 3 ]. Creatinine, on the other hand, is a waste product created from the normal wear and tear of muscles. It is produced from creatine, a protein that helps generate energy for muscle contractions.
Creatinine production essentially reflects muscle mass, and because this mass changes little from day to day, creatinine production tends to be fairly constant [ 3 , 4 , 5 ]. Creatinine is removed from the body by the kidneys, which filter almost all of it from the blood into the urine, at a fairly constant rate.
That is why blood levels are usually a good indicator of how well your kidneys are working [ 3 , 4 , 5 ]. So to recap, BUN levels fluctuate, while creatinine is removed at a constant rate and its blood levels are usually stable. Work with your doctor or other health care professional for an accurate diagnosis.
It is important to address any health condition that may be causing the disbalance. Your doctor will work to find an accurate diagnosis and an appropriate treatment plan, which may include some of the strategies below.
Never use any of these in place of what your doctor prescribes. Again, disbalance between BUN and creatinine is often due to a serious medical condition and it is important to address it.
