I'd really appreciate advice regarding my recent blood tests. I was diagnosed with Graves disease ~2006 and treated with block and replace therapy. After a relapse and a second round of block and replace I elected to have RAI in 2012 and have been on 100mcg thyroxine ever since. Whilst I can't say I felt brilliant it was ok and my main issue was dry eyes.
I had a private blood test in December 2016 as I was feeling tired and cold with achy joints and was curious on my T3 levels (GP never mentions those!):
TSH = 0.711 (0.27-4.2)
Free thyroxine = 17.07 (12-22)
Total thyroxine T4 = 132 (59-154)
Free T3 = 4.13 (3.1-6.8)
Thyroglobulin antibody = 25.71 (0-115)
Thyroid peroxidase antibodies = 9.39 (0-34)
Vitamin B12 = 120 (191-663)
Serum folate = 1.54 (3.89-26.8)
Ferritin = 7.18 (13-150)
So I went back to my GP in early February who insisted on a full blood test:
Serum B12 = 195 (150-99999)
Serum folate = 2.4 (4.2-19.8)
White blood count = 8 (4-13)
Haemoglobin concentration = 111 (115-165)
Haematocrit = 0.369 (0.35-0.47)
RBC count = 4.57 (3.9-5.6)
MCV = 80.7 (73-100)
Mean cell haemoglobin level = 24.3 (26-32)
Mean cell haemoglobin concentration = 301 (300-350)
RBC distribution width = 16.1 (11.8-14.8)
Serum ferritin = 6 (15-150)
Serum TSH = 2.11 (0.25-4)
Free T4 = 16 (12-22)
I am feeling awful. I am exhausted. My eyes are painfully dry and I've had a couple of episodes where there has been a small area of vision that has suddenly gone blurry which after 10 mins has passed. My skin is so dry. I drop things and my balance is sometimes off. My memory is rubbish - I forget things I've just read. I can't even remember if I listed all my symptoms to my GP.
My GP has given me iron and folate tablets. However she said my B12 is in range so that's nothing to worry about. Whilst it being in range is true is it near the bottom at 195 (150-99999) so should I still be concerned? Should I go back and push this?
Thanks for reading this far. Any advice would be gratefully received.
