Hi, I'm having b12 loading dose at the moment ( after active b12came back bottom of range and MMA at 708 range being 0-280). The day after my 2nd injection I had a blood test to check Thyroid, ferritin, folate, IF and rbc.
Some results are back today and wondered if anyone can tell me if it's normal for TSH and T4 to change after starting B12 please?
Have given my previous results too...
TSH 1.88mu/l (0.35-3.50) T4 15 pmol(8-21)
Ferritin 12ug/l (23-300). B12 456
TSH 0.42. T4. 17
Ferritin 142. B12 261
I was having repeated sinus/ ear infections all last year so not really sure this ferritin was accurate?
TSH 3.18 T4 13
Should have had folate and IF but awaiting these on printout once okayed by Doc.
Also diagnosed with low vitamin d 28nmol 50-120 last Feb and mild oesteopaenia. Took supplements, but stopped last Autumn as I couldn't be sure if they were part of the reason for feeling so ill and the persistent infections?
I thought the ferritin had prob gone down as I'm feeling more breathless, heavier periods back again and much shorter cycles so that's why I requested retest. I know I'll be told that it's fine as it's only ever been just over range for years.
Just wondering whether I should be requesting an iron panel and if so is it best not to start supplementation beforehand please?
Also, if I should expect my thyroid results to have changed after 2 injections and should I just retest later on, or look into checking antibodies do you think, that would be privately as have requested them before- no go. My nan (dad's mum) had treatment for overactive thyroid and Mum had a nodule?
Once again, many thanks for looking at these, not really sure if it's a B12 question for the PA site or a Thyroid question!
P.s am not feeling any better from b12 yet...4 the injection today, but realise that's expecting a bit much! thanks Jo
