This is the central medical mystery of the episode. Dr. Cox has been unable to diagnose this patient for two years. J.D. and Turk accidentally discover the diagnosis when they leave a urine sample in the sun and it turns purple, leading them to google 'purple pee' and discover the rare genetic disorder. The diagnosis becomes a key plot device that helps Dr. Cox reconsider his stance on Dr. Kelso.
