How serious is a BUN CRE ratio of 26?

A BUN (blood urea nitrogen) to creatinine (CRE) ratio of 26 is considered elevated, which may indicate potential kidney dysfunction or dehydration. Typically, a normal ratio ranges from 10:1 to 20:1. An elevated ratio can suggest prerenal causes, such as reduced blood flow to the kidneys. However, further evaluation and context, including kidney function tests and patient history, are necessary for a definitive diagnosis.
