I would appreciate any help with these bloods TSH 0.11 (0.15-4.00) FT4 20.4 (9.9-20.7) had my thyroid removed about 3 years ago due to a suspected cancer, which it turned out not to be. I am not sure what difference and/or which bloods are relevant now or if it makes any difference. Have tried to find some info on this with no luck. I am cold, constantly tired, brain fog and have no energy. They did not do FT3 this time. In the past pre TT my (good) endo always insisted they take FT3. Since his retirement I got bumped off the Thyroid Clinic. Was told I had Graves but they were not sure 100 percent sure (surprise) I could have Hashimotos. I have other issues namely chronic lymphocytic leukemia and going for treatment in June (not so chronic only had it a just over a year). I know there are implications from the CLL but this is the second blood test that has come back with these kind of results from the thyroid. I am sure that the CLL is probably the main reason for the tiredness but not sure what the relevance of the TSH and FT4 are since TT. I am guessing that I am slightly overactive but not sure whether to reduce my meds on 175 thyroxcine at moment. I am reluctant to reduce the meds in case I get even more tired (if possible). I would be grateful for any thoughts on this.
