That would be total folly. For some things, like blood type, certainly. Do not take that at face value. But I highly doubt anyone with half a brain would ignore medical information on a patient saying "I am severely allergic to drug XYZ" and turn around and give them drug XYZ explaining that away as "Well, the allergy alert info I found on the patient was not official". It would take a special kind of stupid to proceed along those lines.
