What is the significance of the urea nitrogen-to-creatinine ratio?

1. The urea nitrogen to creatinine ratio is meaningful in reflecting whether renal function is normal and the severity of damage. It is recommended to choose a formal hospital for examination to ensure the accuracy of the test results.

2. The urea nitrogen to creatinine ratio can reflect the degree of glomerular filtration function damage. When the creatinine intake from exogenous substances is stable and the creatinine production in the body is constant, the creatinine value will also change according to the glomerular filtration capacity, with urea nitrogen being more accurate. Therefore, the observation of urea nitrogen to creatinine ratio data has clinical significance.

3. The urea nitrogen to creatinine ratio is mainly obtained through blood tests. When the value is higher than normal, it may indicate improper medication, high-protein diet, gastrointestinal bleeding, renal diseases, etc. Conversely, it may indicate hunger, low-protein diet, severe liver failure, diuresis, dialysis, etc.

4. Avoid consuming too much oily and high-protein food and refrain from excessive alcohol consumption the day before the test, as it may affect the accuracy of the test results.
