Bingley: My Medic Alert medallion has my name; blood type & rh factor; medical conditions (e.g. Drug allergy, ) & my ID number + the Medic Alert 800 number. On file at the Medic Alrert database is a longer medical history and emergency contact info. The hospital calls the 800 number, gives your ID number and can access the info. I'm not sure if they can also do it on-line. I'll inquire.
