A change in urine color can be distressing for patients and physicians alike. Many of the causes of abnormal urine color are benign effects of medications and foods; however, a change in urine color may be a sign of an underlying pathological condition. The good news is that in many cases the diagnosis can be determined from a thorough history and urinalysis. This article presents many of the conditions physicians may encounter and will help them form a narrow differential diagnosis and treatment plan.
