I don't know. It should but something wasn't clear. The point is that for some reason they didn't make a quick call to clarify and seemed genuinely confused about this suggestion. Instead they ran the tests again.
I have a hypotheses. My experience with doctors (that is, general practitioners) is that they think very highly of themselves but usually aren't actually that good at their job. Consequently, they believe they know everything and other doctors know nothing.
It's possible I've just had a lot of bad doctors though.
