You need to have the TSI antibodies checked. If you test even at 1%you have graves. ATG and TPO antibodies can also be found in someone with graves disease. From your first post the TSI is the only one not mentioned. TPO is an inflammation marker. The rise usually happens after the AB's have attacked the thyroid. Of course you may just have a toxic nodule, but you'll find out what the cause is after your tests.
