Hi, is there a specific test to ascertain whether an episode of hyperthyroidism was due to Graves or Hashimoto? High free T3 and T4 (low TSH) at the end of Nov. Free T3 and T4 normalised by 15/12 but still undetectable TSH. Antibody test on 15. 12 thyroid peroxidase IGG AB 144 (range 0-50). Endo suggested Graves on the basis of this.
Antibody thyroid peroxidase IGG AB repeated on 2/2 128 (range0-50). Free T4 12.1 (was 18.6 Mid-december. Range 10.5-24.5).TSH still undetectable.
Previoys suggestions here have mentioned possible Hashimoto. Trying to speak to GP to convince her to carry out vitamin testing and a more specific antibody test to determine whether Hashimoto or Graves. On waiting list for ultrasound.
