Causes of Increased BUN & Creatinine Unrelated to Kidney Function Creatinine and blood urea nitrogen, or BUN, are both nitrogen-containing waste products generated by muscular activity. Many patients panic if lab results come back with elevated creatinine or BUN. This is understandable because these values can be red flags for kidney disease. A single abnormal lab value should never be cause for panic, however. Creatinine and BUN can be elevated because of dehydration, drug reactions, heart disease and surgery. Video of the Day

Kidney Function Test Values: BUN and Creatinine On the other hand, higher-than-normal BUN levels are a big indicator of the fact that something is impairing the excretion of adequate amounts of BUN. We already know urea is excreted in the kidneys, so it's no shocker that elevated levels of BUN point to this.

Regular blood work test should be done for patients with kidney problem.

Test Center Clinical Significance. The BUN/Creatinine ratio is useful in the differential diagnosis of acute or chronic renal disease. Reduced renal perfusion, e.g., congestive heart failure, or recent onset of urinary tract obstruction will result in an increase in BUN/Creatinine ratio. Increased urea formation also results in an increase in the ratio, e.g., gastrointestinal bleeding, trauma, etc. When there is decreased formation of urea as seen in liver disease, there is a decrease in the BUN/Creatinine ratio. In most cases of chronic renal disease the ratio remains relatively normal.

Symptoms of Elevated BUN Here, we will mainly introduce common symptoms of elevated BUN. 1. Nausea or vomiting. Nausea or vomiting is a torturous symptom that occurs easily when BUN is elevated. BUN is the abbreviation of blood urea nitrogen which refers to the level of urea nitrogen in blood.Urea nitrogen is the end product of protein.. Tiredness. Kidney disease patients with elevated BUN may find they become tired easily and this is usually caused by renal anemia which is diagnosed when red blood cell account is lower than the normal range due to kidney disease. 4. Foamy urine. Foamy urine is the clinical manifestation of proteinuria.

What Is Considered Dangerous High BUN Level If so, you will get the result— the BUN to Creatinine ratio. It is more accurate to judge how well your kidneys are functioning. The normal BUN to Creatinine ratio for anyone over 12 months of age is a 10:1 to 20:1. They are designed to show the levels of kidney dysfunction the patient has. It can also be used as a measuring device to see if a kidney disease treatment is working or if the illness condition is worsening. Tag: High BUN Level.

What Does Elevated BUN/Creatinine Ratio Mean Both high serum creatinine (Scr) and high blood urea nitrogen (BUN) can reflect the damage degree of glomerular filtration rate. If BUN/creatinine ratio increases, it may indicate some disorders. Creatinine and BUN levels. In addition to kidney disease, BUN level can also be affected by some other factors such as high-protein diet, hemorrhage of digestive tract, dehydration or high metabolism.

What Does a High BUN Count Mean? Quick Answer. A high BUN count usually indicates that the kidneys are not working properly, but there are other issues that can cause high results, as stated by Mayo Clinic. Some other causes for a high BUN count are a high protein diet, dehydration and congestive heart failure. BUN is an acronym for blood urea nitrogen, and results can vary depending on an individual's age as well as the lab that processes the test, as explained by Mayo Clinic. Shock, severe burns and some medications, such as certain antibiotics, can also cause higher-than-normal BUN results. Doctors consider a BUN test a standard type of blood test and use it to measure the amount of urea nitrogen in the blood. The liver breaks down proteins in the body, which causes ammonia production, according to Mayo Clinic.

Medical Dictionary Test Overview. A blood urea nitrogen (BUN) test measures the amount of nitrogen in your blood that comes from the waste product urea. Urea is made when protein is broken down in your body. Urea is made in the liver and passed out of your body in the urine. A BUN test is done to see how well your kidneys are working. If your kidneys are not able to remove urea from the blood normally, your BUN level rises. Heart failure, dehydration, or a diet high in protein can also make your BUN level higher. Liver disease or damage can lower your BUN level. A low BUN level can occur normally in the second or third trimester of pregnancy.

- What Is a Blood Urea Nitrogen Test? A blood urea nitrogen (BUN) test checks kidney function by measuring how much urea nitrogen is in your blood. Urea nitrogen is a waste product from the breakdown of protein in the body. Normally, this waste is filtered by the kidneys and leaves the body through urine. Too much or too little urea nitrogen in the blood could signify kidney problems.
