I was detained and sent to the hospital, who took a blood sample and I had not been arrested or charged with anything or made aware of anything happening to me other than my eventual transfer to a mental hospital.
There is no single "record" for people. Various offices of our government keep files/records on people for various reasons.
The type of event you've described would usually be private, but there might be records which might be subject to a public record request, if a party knew to ask about the record. Court records for commitments are usually NOT public records. Police reports on this kind of event might be public, but that's only a problem if someone knows to request records for John Smith, for the time period of Jan 1, 2016 through March 31, 2016, or whatever.
It can also depend on who is looking for the record. Government records are usually there for the government to see, as opposed to your neighbor looking for the record, for instance.
