123 views

A high BUN (Blood Urea Nitrogen) to creatinine ratio does not definitively mean kidney failure, but it can be an indicator of potential kidney problems or dehydration. The BUN to creatinine ratio helps doctors assess kidney function and hydration levels. High levels may suggest reduced kidney function, dehydration, or other conditions. However, kidney function cannot be assessed solely on this ratio; other tests and clinical assessments are equally important for a comprehensive evaluation. Always consult a healthcare professional for an accurate diagnosis and treatment plan.
