I posted on the following blood test results on the forum back in December as I have been suffering from very achy arms for over a year (2 years 3 months on Levo for hypothyroidism, already treated for Vit D) and want to know if this could be the result of thyroid issues.
December thyroid results:
Serum TSH = 4.22 mU/L (0.35-5.00)
Free T4 = 15.6 pmol/L (9.0-19.1)
It was recommended by volunteers on the forum that I ask my GP for an increase in Levo dose (I'm currently on 100mgs) showing him the Toft article as the TSH was at the top end of the normal range and it should be below 1, ideally. (I had asked him before this result for an increase based on my symptoms but he said no.)
Anyway, I decided it might be a good idea to get a private, more comprehensive test done first to see if I have a T3 conversion issue or if any other problems show up which might convince him to adjust or change my meds.
The results from this are as follows. Everything else seems normal except the antibodies. The TSH seems lower but the measuring unit and ranges are different so it's hard to tell. Though what does the positive last result mean? Is that significant even given that I have a known thyroid condition and am already on Levo?
TSH: 1.91 mIU/L (0.27 - 4.2)
Free Thyroxine 18.8 pmol/l (12.0-22.0)
Total Thyroxine (T4) 99 nmol/L (59-154)
Free T3 4.8 pmol/L (3.1-6.8)
Thyroglobulin antibody 24.2 IU/mL (0-115 ) (Negative)
Thyroid Microsomal Ab (Conf) Positive - Titre of 1 in 25,600

I would be interested in any reactions to this so I am forearmed before going back to the GP. If everything is totally normal I could have difficulty persuading him my symptoms are thyroid related...
