Hi, I have taken my regular Thyroid tests and it is showing a elevated TSH - 3.58 but total T3 and T4 is in normal range. I am under thyroid medication from past 5 years. I went again the next day for Free T3 and T4 test, the did TSH again, and it was 5.85! But, Free T3 and T4 were within the range. Also, I got the Anti-thyroglobulin test done and the result was 247.50. Can anyone tell me why the TSH fluctuation is so high in a day's interval and what is the significance of Anti-Tg being positive and at this level?

Raised antithyroglobin antibodies are suggestive of autoimmunity as the cause of hypothyroidism. Monitoring of thyroid function is done by TSH estimation because T3 and T4 have a very short half life. As per your reports you need to increase your thyroid supplement in consultation with your Physician.
