I was diagnosed as hypothyroid when I was 18 by my GP in South Africa, placed on Levothyroxine and told this is just how it will be for the rest of your life.
Fast - forward 20 years, a move to the UK 13 years ago, a mix-up and problem in getting my prescription, - long overseas trip etc. I have not been taking Levothroxine for 2.5years now. I started following up with my UK GP as to why I was on Levothyroxin for all this years but now, when off the medication, when tested, all my levels were 'normal'. It just didn't make sense. So she had both my thyroid antibodies tested, with these results:
A-thyroglobulin - 302 (0-60)
A-TPO - 400 (0-60)
TSH - 3.6 (0.3-5.5)
Free T4 - 11 (9-25)
However, she said that the antibody results were historic, and did not indicate that I had Hashimoto's at this moment, that when our antibodies were elevated, they stayed elevated and didn't come back down. Which sounds like hogwash to me... Has anyone else experienced something like this? Is it possible for our antibody results to mearly be an indication of a 'historic' problem? She has since requested an Endo appointment for me, so I will be asking them some more in-depth questions.
