The blood urea in Delhi measures the level of urea nitrogen in your blood. Urea nitrogen is a waste product that is filtered out of your kidneys, where it travels to your liver, which converts it into urea and releases it in the form of urine. This bun test in Delhi may also be performed when you have symptoms of kidney disease or are being treated for any condition that affects the kidneys. If you have high blood urea nitrogen in Delhi levels, you may need treatment so that you don't get any worse than you already are (called "progression"). Sometimes this means taking medicine and changing some things about your lifestyle (for example, losing weight). The blood urea nitrogen Delhi test is usually ordered along with other tests when someone has symptoms that may indicate kidney disease or liver disease. The test is also used as part of a routine physical exam to help diagnose conditions such as dehydration or malnutrition.
