the repeat thyroid tests are again another blood test, honestly the peds endo might get a specific type of thyroid assay called 3rd generation or there are others called equilibrium dialysis that are more specific in a situation like this-sometimes antibodies get in the way of accurate measurement of thyroid. Many labs are variable and sometimes we see an unusual test with one time and another one that is normal. Samples are mixed up or perhaps run in a way leading to slightly abnormal results. So let the peds endo get the labs they need including perhaps repeating antibodies if needed, let them decide based on the presentation whether treatment is needed.
Sorry about the all caps, it's something i've always done.
WE ARE STILL WAITING FOR MY DAUGHTER'S THYROID ANTIBODIES RESULTS. WHAT I DO NOT UNDERSTAND IS, HER 1ST TSH TEST WAS VERY HIGH. HER 2ND TSH RESULT WAS NORMAL. BOTH BLOOD TESTS WERE DONE ONLY 4 DAYS APART. HOW OR WHY COULD THE EXACT SAME TEST, 4 DAYS APART BE SO DRASTICALLY DIFFERENT? OUR FAMILY DR EXPECTS HER ANTIBODIES RESULTS TO COME BACK POSITIVE, IN WHICH CASE HE WILL REFER US TO A PEDIATRIC ENDOCRINOLOGIST FOR FURTHER TESTING. WHAT KIND OF FURTHER TESTING WOULD A PEDIATRIC ENDOCRINOLOGIST DO? THANK YOU. I promise I will work on no more all caps.
I know you are concerned, first thing, take your keyboard off of caps lock!!! :)
Now I get so many crazy thyroid labs back and you are so right, we need to correlate things with how the patient is doing. So unfortunately there may have been a lab error and your doc no doubt is just as confused as you are (and I am!)
I need you to call your pediatrician and ask for a referral to a pediatric endocrinologist. There are specific thyroid assays that are better than others and if there are antibodies this can also be tested for.
Hashimoto's is an autoimmune thyroid disorder in which our body makes antibodies that cross react per se with our thyroid gland and enzymes that the gland makes. These antibodies can attack the gland, causing inflammation (goiter) and sometimes (usually) and underactive thyroid gland, therefore the free T4 and sometimes total T4 may be low and we will see a higher TSH which is the hormone that the brain is making to regulate the thyroid gland(so if the thyroid falls down on the job the brain tells it so with more tsh).
So the first test made me feel she was hypothyroid but who knows what happened with the second test. If she has antibodies this would make me look further.
where do you live?
Ok now breathe easy, she is going to be ok, you will get this sorted out-no more caps lock promise?
