What is the name of urea nitrogen on the test report

Urea nitrogen is usually labeled as BUNBloodUrea Nitrogen on the test report, and some hospitals may directly use the Chinese name "urea nitrogen" or "blood urea nitrogen". This indicator reflects the renal excretion function and protein metabolism status, and is one of the core items of routine renal function examination. Urea nitrogen is the final product of protein breakdown metabolism, mainly excreted from the body through glomerular filtration. An increase in BUN values on the test report may indicate decreased kidney function, high protein diet, gastrointestinal bleeding or dehydration, while a decrease may be related to low protein diet, abnormal liver function or pregnancy. During testing, it is necessary to fast for 8-12 hours to avoid vigorous exercise that may affect the accuracy of the results. Different medical institutions may use millimoles per liter or milligrams per liter as units, with reference values typically ranging from 2.9-8.2 millimoles per liter or 8-23 milligrams per liter. If abnormal urea nitrogen is found, it is recommended to conduct a comprehensive evaluation based on renal function indicators such as creatinine and uric acid. Daily protein intake should be controlled, with a daily water intake of 1500-2000 milliliters, to avoid overuse of nephrotoxic drugs. Diabetes patients should regularly monitor blood sugar, hypertension patients need to strictly control pressure. When continuous abnormal values are found during physical examination, it is necessary to seek medical attention in the nephrology department in a timely manner and complete urine routine, renal ultrasound and other examinations if necessary.
