I have hypothyroidism. I also tested positive for anticardiolipin for APS. Have to go for 2nd test still. When I 1st started on synthroid helped but now sptoms coming back. Never tested for antibodies though. Being I tested positive for anticardiolipin I thought I should be tested for thyroid antibodies too. I do go on thyroid U K some valuable info there as on here. Just wanted to know from this forum too if it's possible to go together.
