Vitamin D, I think from a couple of years ago (after I was put on prescription Vit D): 43 nmol/L (reference range 25-170 nmol/L)
B12 in 2008: 520 ng/L
Folate in 2008: >24 mcg/L (i.e. their testing only went up to 24mcg/L)

What do you make of that, apart from the B12 being quite a long time ago? From having a quick look, I can't for the life of me see how they think that the Vit D is normal, but perhaps that's actually from before I was put on the prescription stuff?

They're going to try to organise a home visit tomorrow to look into the itching. They did offer yet another antihistamine, but I feel that I've been on so many antihistamines by now that if they were going to clear it up, they would have. Should I ask for any blood tests, either with respect to the B12 or the itching? Or would being on B12 supplements now cause problems with the blood tests? I'm only on 250mcg at the moment, since I've just started and I'm raising it slowly.
