I tested for thyroid markers recently.I was already diagnosed last summer with hypothyroidism and am medicated with Levothyroxine, so the values of TSH T4 are now in the control range with T3 low borderline.
However, anti Tg came positive at 570IU/ml which I understands suggests autoimmune underlying cause? Does that mean Hashimoto possibly something else?
Yes, autoimmune thyroiditis. If you have a goitre then it's Hashi's. If no goitre then it's Ord's. But they are treated exactly the same: thyroid hormone replacement. 
Many thanks for your reply. What is Ord's?
It's Hashi's without the goitre. That's all.
Mr Hashimoto 'discovered' a form of hypothyroidism with raised antibodies, where the thyroid is slowly put out of action. And it was recognised by a goitre in the neck. The disease was originally named after him (although UK GPs never use that name anymore).
Then came along Mr Ord, who discoverd that you don't have to have a goitre to be suffering from autoimmune thyroiditis. Same antibodies, more or less the same results. Only with Ord's, as there's no goitre, the thyroid shrivels up to the size of a small pea. So, that version of the disease was named after him. But, again, the names is very rarely used. And patients tend to call it all Hashi's, anyway.
Ohhh that is helpful. Thank you greygoose.I had inflamation there post covid in 2020 and symptoms for over 2 decades. One wonders how I only found out about it recently. Through this group I realised I should take the antibody test and indeed it made the picture slightly clearer. Best to all xx
