High blood urea can be an indication of underlying health conditions such as kidney disease, liver damage or heart failure. Blood tests are commonly used to diagnose high blood urea levels. The test measures two key components - Blood Urea Nitrogen (BUN) and Creatinine. Learn about the blood urea nitrogen (BUN) test, which measures the amount of urea nitrogen in your blood and indicates how well your kidneys work. Find out the normal range, causes, and treatment of high or low BUN levels. Measuring urea levels in the blood, commonly referred to as Blood Urea Nitrogen (BUN) or simply serum urea, helps assess kidney function and overall metabolic health. This blog post will explore the normal range of urea, causes of abnormal levels, the procedure for urea testing, and the treatment options available for managing abnormal levels. Explore the significance of the blood urea normal range and its health implications. Learn how it affects kidney function and overall wellness. Read more.
