High free t3

[mtkst13]

Hello.

A couple of months ago i had routine blood work done because i take sertraline.  unexpectedly, my tsh value was <.004.  i redid the labs two days later and my tsh was <.02.  i was then referred to an endocrinologist.  

she prescribed more tests, TPO, TSII, etc.  the only thing elevated was my antithyroglobulin.  my tsh was again <.004, my free t3 was elevated at 5.2, and my free t4 was normal.  my raiu was low (like 1.6%) and my sonogram showed nothing out of the ordinary other than some swollen lymph nodes around my thyroid.

cbc and such were normal.  creatinine and creatinine to something? ratio was elevated.

my endocrinologist feels that i have silent thyroiditis unrelated to pregnancy/postpartum (my youngest is 2 years old).  i am to go back in august for follow up.

does this sound right?  should i be concerned about anything else.  cancer?

thanks,
mia

Sounds like a transient thyroiditis based on the RAIU of 1.6% but usually the T4 is higher than T3 in these cases -- give it some more time (early august appropriate) and retest to see what the pattern is -- if thyroiditis is correct, the numbers will show normal or hypothyroid by then.  The lymph nodes swell in thyroiditis -- this is common.
