Prior to my mixed-results meeting with the Endo a couple of weeks ago I went for a load of bloods, including TPO-Ab, which came back as still highly positive (20 years after first diagnosis). The Endo said she would be surprised if my thyroid gland was not completely atrophied by now so I asked her, if this was the case, why I was still producing antibodies.
I'm not entirely sure I remember the answer correctly but I think it was a case of 'once you have antibodies you'll always have antibodies'. It just seems a bit strange, if my thyroid's dead 'n' buried, to still have them.
Does anybody know the answer to this?
