“My dear, at Quest Diagnostics vitamin D levels are checked as part of your blood panel.”
My dear, my testing is not done at Quest. There are a bazillion results, but D levels is not one of them. Also, I expected iron results but that was not one of the tests, either.
Tell them what D levels you want. My Docs....I phoned them up and told them what blood tests I wanted. The silly girl on the phone asked me who (what doc) ordered them. I told her I ordered them myself...and they got done by Quest.
