I've been on the TUK boards for a while but am new here.
I'm hypothyroid on t3 and t4. I responded very well to t3 for about six months but now I'm back to how I felt on t4 alone. My thyroid test results look good but I feel like a wet noodle and I realised that I have some other PA symptoms (numb toes, breathlessness, apathy, brain fog, tinnitus, and my most recent cervical smear was abnormal but colposcopy showed no lesions).
I've been supplementing for a couple of years (lots of supplements, esp b vitamins and d) and had good b12 results when tested in Jan 13 (I was probably still supplementing because I didn't know they were planning on testing b12).
In Jan 13, my b12 was 861pg/mL (191-663).
In Feb 14, my most recent results (I had stopped taking supplements, incl iron, for about a month before) were:
Serum b12 332ng/L (180-914)
Also had the following:
Serum ferritin 19ug/L (11-336)
Serum folate 18.7ug/L (3.1-19.9)
Serum d 86 nmol/L (76-220)
So, my questions are:
a) Does this look like possible PA? Or considering my ferritin, is it plain old anaemia?
b) Do I begin supplementing with a patch or injections to see if it makes me feel any better?
c) Should I have an antibody test or an active b12?
