My thyroglobulin and anti thyroglobulin antibody
levels remain low, however in a recent
blood test, the TSH level rose to over 6. My T4 levels remain close to the upper limit where they should be for TSH suppression (at the moment free T4 is at 1.68ng/dL). Is there any reason why the TSH level jumped in such a way?
It will be over a month before I can see my endocrinologist again, which is why I'm here.
