A medical identification tag is a special type of medical jewelry that you wear on your wrist or neck. It is like a special marker that lets other people know you have a medical condition that may affect the way you are treated in an emergency.
Think of it like a superhero's emblem that tells people about their powers. But instead of superpowers, your medical identification tag tells other people about your health condition.
A medical identification tag usually has your name, your medical condition, any allergies you may have, and emergency contact information. You wear it all the time, so if something happens, doctors and paramedics can quickly read the information on the tag and give you the right care that you need.
So just like how you wear your seatbelt to keep you safe in a car, you wear a medical identification tag to keep you safe in case of an emergency.
