Hi. My TPOab over the years have been in range, last year was 18 (<35). TGab also in range. I am getting an ultrasound done this week to check for nodules.
Is an ultrasound more sensitive than antibody markets for detecting Hashimotos? I really hope it will get me some much needed answers.
Long story short, in 2013 my TSH was 5.30 and in 2014 was 4.20. Latter test done in afternoon so was bit lower, safe to assume 8 months apart the TSH was barely in range (0.30-5.30) and T4/T3 (tested only with the 4.20) was respectively 36% and 24% in range, TPOab was 11 (<35).
Right now on 112mcg Synthroid I had these test results.
FT4 14.0 (10.6-19.7)
FT3 4.05 (3.00-5.90)
FT4 and FT3 are just over a third in range, 37% and 36%. TSH dramatically dropped by around 1.5 points without subsequent rise in FT4 10 months ago since beginning stimulant medication for ADHD (possible dopamine interference in thyroid axis, though for most people the lowered TSH is supposed to be transient).
Me and my doctor are quite confused as to what’s going on. He explained that the risk of increasing Synthroid, if we were to dose to bring up FT4/FT3 while ignoring TSH, is to make my body dependent on Synthroid and kill the thyroid, so I’d have to take Synthroid for the rest of my life. Though I do think the lowered TSH is purely artificial from the stimulant medication, so the low TSH shouldn’t scare us anyways.
