My endocrinologist tested for thyroid antibodies - there mere presence of those alone was enough for a diagnosis of Hashimoto's disease. My actual T4/TSH levels were on the low side of normal - so a typical GP would likely have ignored this. But given the antibody test and the symptoms my endo focused on those first. Fortunately he's been pretty emphatic about not just chasing numbers on a chart.
