Hello all,
I did my regular thyroid tests through medichecks recently, and the main thing it showed up was low vit D and low b12. I've decided to work on raising these before changing my thyroid meds.
Because I've been having more migraines recently I've booked a docs appt and I'm going to ask to be checked for pernicious anaemia, due to symptoms and a family history. What I would like to know is whether if I start a b12 regime now (about a week before my doctors appointment) that will affect any pernicious anaemia testing?
