Help understanding lab results

Hi:
All of my T3 levels, in the past year have been normal, except Reverse T3 which has been low. These were ordered by one Primary Care MD. I am now trying a new Primary Care MD who ordered tests last week. She ordered Free T4 and TSH which were normal, but then there were two tests that were quite abnormal. They were:
Thyroglobulin Antibody 0.0 - 0.9 IU/mL My result was 3.5
and
THYROID PEROXIDASE AB (TPO) 0 - 34 IU/mL My result was 102

I am pretty freaked out. Could this mean I have thyroid cancer? I would be SUPER appreciative if those of you who know how to interpret these lab results could respond.
Thank you.

Most likely this is a positive sign for Hashimoto's Disease which is an autoimmune disorder. It can be treated.

Many on this board are very informed about the thyroid and I am sure someone will answer your question in due time. Meantime, I would not worry about cancer.

Elevated TPO and TgAB are signs of Hashimoto's Thyroiditis. If all your other thyroid tests are normal, then your doctor may want to take a wait and see approach. I can't remember the ranges off the top of my head, but if you Google "optimal thyroid levels" and then look at images, there's a chart that shows the ranges and where the levels are optimal. It's definitely something you'll want to keep an eye on because Hashi's is an autoimmine disorder in which the immune system sees the thyroid as a foreign body. Because of this, the immune system attacks the thyroid, and in the case of Hashi's it can cause hypothyroidism.

One thing you can do to prevent this attack is to follow a gluten free lifestyle - Paleo is a good starting point. The reason for this is the wheat protein molecule is one molecular deviation different from an enzyme in the thyroid. If your immune system is already on alert to attack, and it starts see gluten, it'll start attacking that, thinking it's your thyroid, then also hit your thyroid. I have Hashi's and hypo and I follow the autoimmune protocol diet (AIP). I have a bunch of food intolerances. I think starting with paleo is fine. Of course it's a personal preference, but I wish I would've done it sooner than I did.
