Hi all - I spoke to a Dr today about when to get my B12, folate and ferritin re-tested. She said, given I am on an iron supplement, my ferritin levels should be tested in 4 months but that B12 isn't usually re-tested until 6 months post-loading injections. Is this accurate in your experience?
She also said it wasn't possible to request the specific blood test that distinguishes active from inactive B12...but knowing how vague and potentially inaccurate the total serum B12 level test is, this seems crazy to me? Do I really not have the right to request this particular test or is she just trying to fob me off again? (I'm in the UK, incidentally).
Still feeling pretty foggy and listless with my head feeling like it weighs a tonne most days. Dr said I probably won't feel better until at least 6-8 weeks after loading doses/starting iron tablets. Hope she's telling the truth!
