The short answer is no. Sometimes we know that, in the cases that get brought before either the law enforcement, or to a triage unit in a hospital or a clinic, the questions about your ancestry or your origins are not ones that are going to be prevalent. It is going to be about drugs or medications or if there is someone they should be contacting.
The questions about where do you come from come after the fact, when the hospital administration or clinic administration is chasing someone down to pay the bill. That's the only time the issue about ancestry or origin arises.
