Hi,
I don't know what do you mean by antibodies for both hypo and hyper, in general, TPOab and TGab can present in patients with graves disease as well as in those with hashimoto,the majority of those with Grave's have TPOab, however, TSIab can be present with Graves disease.
5% of the people with normal thyroid function have TPOab.
