title: Povidone iodine as a cause of factitious hematuria and abnormal urine coloration in the pediatric emergency department.
abstract: The observation of a cola-colored dipstick positive for "hematuria" was made in an 11-year-old black male who presented to the emergency department with a chief complaint of dysuria. Thorough questioning eventually revealed the source of these two abnormalities to be the addition of povidone iodine to the urine sample. The reported causes of abnormal urine coloration and of false positive dipstick hematuria are summarized.
