Unusual Urine Color Presentations

From understanding hydration levels to testing for early signs of disease, urine can be a great way to understand a person’s health. But, when urine turns a color of the rainbow other than yellow, it can be a big surprise. Do you know the cause and management of these five unique urine color presentations?

1. Glowing Urine

A 17-year-old is found collapsed in their home, unconscious and unresponsive. EMS is called and the patient is brought to the hospital. On physical examination pupils are reactive to light, but muscle reflexes are hyperactive. The patient seizes twice in the four hours since their admission. When a UV light is held up to the urine, it glows a neon green.
