but you are being asked, so the point stands.
Anyway, It's a choice to be offended by trivial things like this. if you know the doctor is trans friendly, which in all likelihood means he's LGBT friendly, I think you can safely assume that either the test is standardized and not made by him(not a reason to be offended, but this may make it outdated), or if it is made by him then there is no reason to take offense.
simple as that really.
