title: Measurement and clinical significance of thyroid microsomal and thyroglobulin antibodies by enzyme-linked immunosorbent assay.
abstract: Using the thyroid microsomal antigen(TMAg) prepared by affinity chromatography gel filtration method of sufficient purity, we measured the TM antibody (TMAb) level by an enzyme-linked immunosorbent assay (ELISA) in 103 normal persons and 183 patients with various thyroid disorders (Hashimoto's thyroiditis, Graves' disease, hypothyroidism, subacute thyroiditis, thyroid cancer, thyroid adenoma and simple goiter). The thyroglobulin antibody (TCAb). T3 and T4 were also measured at the same time. Based on the measurement of TMAb and TGAb of the thyroid diseases and analysis of their incidences and titer, our data strongly support that ELISA using purified TM and TG is a very useful and promising method for diagnosis and distinguishing autoimmune from non-autoimmune thyroid disease, and also can be employed in monitoring the development and studying the pathogenesis of the disease. We found that there is a negative correlation between TMAb titer and T3, T4 values (P less than 0.01) which has not been reported before in the literature. According to the result of the study, we suggest an immunological classification of thyroid diseases.
