Re: Another one of those 'Lab Results' threads.
Mac, you have Hashimoto's thyroiditis, which is causing hypothyroidism. Hashi's is an autoimmune disease, evidenced by high titers of TPO and/or Tg antibodies. The antibodies are slowly destroying your thyroid gland, making it incapable of producing enough hormone for your needs.
Your high TSH is your pituitary gland's attempt at getting your thyroid gland to make more hormone than it can now make, due to the damage the antibodies have caused.
You haven't mentioned symptoms. Do you have any? If you do, then your T4 and T3 aren't adequate for your needs, even if they are within range. Very few people who are diagnosed by having elevated TSH has T4 or T3 below range. It's quite common to be diagnosed with labs like yours.
You can find lots more information in our "Thyroid Information" sticky thread.
