My TSH was 1.9 and my free t4 was 1.7. I had an ultrasound done this am and my MD started me on a small dose (25mcg) of synthroid . I just took my first dose this am.
Yes other patients have been diagnosed with Hashi's by ultrasound results and biopsies because for some reason their labs don't show right away. Also, did your Dr run ALL of the antibody tests for Hashi's? There is more than one and some only test positive for one rather than all.
When you say your TSH is normal what was the exact number? The ranges have changed. Also it is a pituitary function test, not the actual active thyroid hormone tests.
You need to have a free t4 and free t3 tests done which are the actual active thyroid hormone in your body. Soooo if your free t4 is low, then this needs to be revisited and see if you would benefit from medication. Has your Dr suggested thyroid meds yet?
Hashimoto's is the most common cause of hypothyroidism, so maybe that's why your doctor said that.
Do you have the actual lab results that you can post, along with the reference ranges, since these are lab specific? If you have those results, please post them.
Did your doctor give any medication (thyroid replacement hormone)?
