I was diagnosed with overactive thyroid, likely graves last year. On block and replace but still having symptoms. New bloods come back today which show TSH IS 1.53 and free T4 is 15.7. My bloods acetal months ago were showing as TSH 20.2 and free T4 0.11. Can anyone say with any certainty that based on my new results I am overactive or even under? These tests make no sense to me and I can't speak to my Endo till Monday. Thanks.
