Hello,
My thyroid was tested January 2010 with the following results:
Free T4: 0.90 (0.7-1.55)
Total T3: (for some reason wasn't tested)
Ultra TSH: 6.94 (0.25-5.0)
I was told to take some non-prescription supplements (iodine & and one containing thyroid gland with thyroxine removed) to help bring my TSH down by my Nurse Practioner/OB GYN. Because I was still having the same symptoms after a few months (episodes where the left side of my neck would feel hot, tender and like someone is squeezing it, achey all over, painful heels and wrists, scratchy eyes, hard to focus, forgetful, cold hands and feet and others)
I was tested again in May 2010 and also had the antibody tests:
Free T4: 0.9 (0.8-1.9)
Thyroglobulin AB: 78 (<20)
Thyroid Peroxidase AB <10 (<35)
Is 78 high enough to be considered indicative of Hashimotos?
Can you still have Hashimotos with a high Thyroglobulin and an in-range Thyroid Peroxidase AB?
Is it most likely that I do in fact have Hashimoto's based on the above test results?
(I was told yesterday about the results, sent my lab work and told to see my Primary Care Physician about getting an ultrasound and a possibly an endocrinologist referral....just trying to wrap my head around some of this before going!)
Thank you so very much for your time and expertise!
Sincerely,
Jen :)
Your FT4 is much too low. The rule of thumb for FT4 is midrange, and yours is way down at the bottom. Many doctors don't test FT3, but it is the most important of the thyroid tests, correlating best with symptoms. You'd most likely feel much better on meds.
An U/S is a good idea. If your PCP feels comfortable and is well-versed in thyroid issues, he might be able to treat you. An endo is not always the be all and end all as many of them specialize in diabetes and really have no interest in thyroid. It's best to interview them before making an appointment to see what they know about thyroid.
