This is utter nonsense, that you also need a positive IgG version of the test. It does not say so anywhere on the entire Internet. She made it up.

I did not have any sedation during endoscopy, and only heard about a few others who got any, the rest were done without here in this country. They do that if you gag too much so it is impossible to perform the procedure. It only takes some minutes anyway.
