Abstract

Complete urinalysis is commonly requested by clinicians, because it provides important information about diabetes, liver or urinary system diseases, hydration, urinary tract infections and many other clinical conditions. The results of complete urinalysis can be influenced by various factors, such as diet, dietary supplements and medications. In this case report, a false-positive urine bilirubin result caused by taking an anti-inflammatory drug containing etodolac was presented.
