What is the normal value of urea nitrogen creatinine ratio

The normal value of the urea nitrogen creatinine ratio is generally 10-20, which is mainly used to evaluate renal function and protein metabolism in the body. The urea nitrogen creatinine ratio is one of the commonly used renal function indicators in clinical practice, which can be obtained through blood testing. Urea nitrogen is the final product of protein metabolism, while creatinine is a product of muscle metabolism, both of which are excreted by the kidneys. The ratio of healthy adults is usually maintained between 10-20, which reflects the normal excretion of nitrogen waste by the kidneys. Fasting blood collection is required during testing to avoid interference from vigorous exercise and excessive protein intake on the results. When the ratio exceeds the normal range, it may indicate dehydration, high protein diet, gastrointestinal bleeding, or renal dysfunction. Maintaining a normal urea nitrogen creatinine ratio requires attention to maintaining a reasonable dietary structure and controlling daily protein intake at 1-1.2 grams per kilogram of body weight. Moderate drinking water can help promote the elimination of metabolic waste, and it is recommended to drink 1500-2000 milliliters of water per day. Regular sleep and moderate exercise can also help maintain normal metabolic levels. If an abnormal ratio is detected during testing, timely medical examination and follow-up should be sought. The doctor will conduct further examination and diagnosis based on the specific situation.
