That was probably the right thing to do. It's called differential diagnosis, and it doesn't mean that the doctors didn't suspect Lupus from the start. They were being careful to rule out alternatives in order of priority.
If your Word document that you're writing has a grammatical error, it could be caused by many things, from a typo to bad autocompletion to hackers messing with your desktop or bad choice of language dictionary packs etc. You don't start the first treatment by rebooting the computer and replacing the whole MS Office suite. You first try a bunch of less invasive things.
