TPO results


Following on from my initial posting of my TSH and FT4 results I have now had TPO results back:

768 IU/mL

negative <60 IU/mL

equivocal 60 - 100 IU/mL

positive >100 IU/mL

I also asked my GP if my nutrient levels could be tested. The GP requested vit B12 and vit D. The lab declined to test my vit D levels! They did however test my vit B12:

Serum vitamin B12 : 295 ng/L (189-883)

The lab has marked the above as satisfactory but I know from reading posts on this site that isn't satisfactory. Could anyone advise me on how much B12 I should take? Does anyone have any recommendations for a particular brand? I did read on one post that it was best to take vit b12 methlycobalamin if I remember correctly?

My GP is referring me to an endocrinologist but if I want my vit D tested or any other tests I guess I'm going to have to pay for them myself.

Any advice would be much appreciated.

Thyroid peroxidase antibodies are positive for autoimmune thyroid disease (Hashimoto's). There is no cure for Hashimoto's which causes 90% of hypothyroidism. Levothyroxine treatment is for the low thyroid levels it causes. Many people have found that 100% gluten-free diet is helpful in reducing Hashi flares, symptoms and eventually antibodies.



B12 295 is low in range but unless you have the symptoms in b12deficiency.info/signs-an... you are unlikely to be deficient. I would ask for advice on healthunlocked.com/pasoc before supplementing.

You can order ferritin, vitamin D and folate via thyroiduk.org.uk/tuk/testin... or your can order vitD only from City Assays. Medichecks do #ThyroidThursday discounts.


Thank you. I have read that 100% gluten free diet can be helpful so I'm going to gave it a go to see if it helps in reducing my symptoms.
