This fast, simple blood test is most commonly used to evaluate kidney function. It's often done along with other tests to make a proper diagnosis. For example, your doctor may order a blood creatinine test. This test measures the amount of creatinine in your blood. Creatinine is another chemical waste product that your kidneys normally filter out of the blood. When the kidneys aren't working correctly, creatinine can build up in your body. The BUN test can help diagnosis the following conditions: liver damage malnutrition poor circulation dehydration urinary tract obstruction congestive heart failure gastrointestinal bleeding The test may even be used to determine the effectiveness of dialysis treatment.
Your healthcare provider may perform this test as part of a general health exam, to help diagnose many illnesses
This test is also used to monitor or evaluate the effectiveness of treatment, once a diagnosis is made and the treatment started
Many a time, the Blood Smear test is ordered as a more definitive evaluation tool after a complete blood count (CBC) with automated differential test has been performed, and a blood disorder/deficiency suspected.
There are two main ways to decrease BUN: Drink more water Eat less protein Ginger may help with the removal of urea from blood. Ginger extract markedly decreased BUN in mice (R). Inhibiting Arginase Arginase converts L-Arginine to Urea. When you inhibit arginase, you decrease urea. The downside to this might theoretically be a buildup of ammonia. Nickel is required for the conversion of urea-form nitrogen to ammonia. A deficiency of nickel leads to a urea toxicity
If BUN results come back as abnormal, medical professionals will usually follow up with other tests. A creatinine test and renal panel can help indicate kidney and liver health. Testing may be done to determine specific substance levels as well, like potassium, sodium, and calcium. Urine tests may also be ordered.
In some instances, physicians may also follow up abnormal BUN results by requesting tests to evaluate the blood creatinine to BUN ratio. The ratio of BUN to creatinine is usually between 10: 1 and 20: 1.
The course of treatment for each person with abnormal BUN levels varies depending on the cause and severity of the case. Those with organ failure often need intensive treatment, and dialysis may be necessary. Lesser BUN problems may simply require long-term monitoring.
In the case of abnormal BUN levels brought about by eating too much protein, people can limit eating food rich in protein, like meat, fish, beans, and dairy, and increasing fruit and vegetable intake. Staying hydrated also helps prevent the buildup of BUN.
BUN levels have also been tied to high blood pressure and conditions that cause restricted blood flow such as diabetes. As stress can greatly impact blood pressure, exercising, seeking counseling, and reducing stress levels may help steady BUN levels. Controlling blood sugar levels can also promote healthy BUN levels.
Test Method 1 : This simple test involves taking a small sample of blood.
Before drawing blood, a technician will clean an area of your upper arm with an antiseptic. They'll tie an elastic band around your arm, which will make your veins swell with blood. The technician will then insert a sterile needle into the vein and draw blood into a tube attached to the needle. You may feel slight to moderate pain when the needle goes in.
Once they collect enough blood, the technician will remove the needle and apply a bandage over the puncture site. They'll send your blood sample to a laboratory for testing. Your doctor will follow up with you to discuss the test results.
