Exactly what bloods shd I insist on?

Hi, having had my t4,and t3 slashed by GP for 7 weeks now I am going to get my bloods done before self medicating until I can get some logic out of NHS wales - ha ha.

I'd be grateful to know exactly what bloods I shd be trying to get my GP to test for as I'm sure it will simply be tsh. I have never been tested for hashis either, is that relevant/ important? What are the implications of being hashimotos in terms of ongoing health? My elderly mum also has hypo. Sorry to keep asking for help this should be the last one. For now.

Sulamaye, Ask for FT4, FT3, thyroid peroxidase (TPOab), thyroglobulin antibodies (TgAb), ferritin, vitamin D, B12 and folate. Labs often decline to test FT3 even if GP's request it unless TSH is suppressed.

It can be useful to know if one has an autoimmune disease as it can predispose one to others but treatment is the same as for non-autoimmune hypothyroidism. TPOab is the most common antibody test but people have had negative TPOab but positive TgAb.

Ferritin, vitD, B12 and folate are often low or deficient in hypothyroid patients. Deficiencies should be treated by prescription but low levels within range will need to be self supplemented.


Thank you so much Clutter, I am going to write to her now and plead for those tests to be done. We shall see....
