Hey mrsD, you said this:

And furthermore, what is very lame about the US, is that the LOWER end of the range is out of date, compared to other countries. Normal is considered 150-200 here and in Japan anything below 500 is abnormal.

And MelodyL (the overachiever ) says that hers is 2000.

I'm not clear on exactly what number we're shooting for on the B12 level. When I first started my search for PN answers, I tested at +800 without supplementation. So is it correct to think that lack of B12 is not a contributing factor to my PN cause in my case? And if it's not, can getting my B12 higher still help?

Sorry if you've already gone over this...if I missed it, you can give me some study hall detentions if you want.
