Hi Anne, I just relized this last year how important it is to ask for the actually test numbers, so you may look yourself, even if ya can't read them. You can always figure it out yourself. I was given my medical file of 5 yrs and looking back on the tests that were run, lots of the numbers were low normal. Of course if the lab doesn't flag it the dr just assumes its normal. I went years with low normal B12 and Iron till I finally started asking for the numbers. Get the facts in front of you, don't relie (sadly) on your dr. Patricia
