[Non bacterial thyreoiditis, diagnosis and differential diagnosis (author's transl)]

Retrospective analysis of signs, symptoms, and laboratory data (BSR, thyroid scan, thyroxine, triiodothyronine, TRH-test and antibodies against thyroglobulin) was performed on 68 individuals. Diagnosis of subacute and of chronic thyreoiditis was proven in 26 patients and 21 patients respectively by cytological examination. It was excluded by the same procedure in 21 patients, in whom there were some indications of these two kinds of thyroiditis. The following mosaic of clinical and laboratory parameters showed a sensitivity of 0.73 at specificity of 0.95 for diagnosis and exclusion of the two diseases: spontaneous pain, pain by palpation, fever, elevated BSR, thyroid scan, free thyroxine index, and TRH-test.
