    摘要: The invention relates to a method for detecting thyroid autoantibodies in a biological sample taken from a patient in the context of differential diagnosis of diseases associated with changes in and/or malfunctions of the thyroid. The process of detecting the presence and/or quantity of thyroid autoantibodies in the sample uses an immunodiagnostic method of detection whereby a measurement signal is provided per detection. Said measurement signal generally represents the presence and quantity of at least two antibodies, including anti-TPO-autoantibodies and anti-Tg-autoantibodies, in the sample. Said method increases the selectivity and sensitivity of the detection of autoantibodies typical for certain autoimmune diseases whilst simplifying the process.

    摘要: In a competitive receptor binding assay for detecting TSH-receptor auto-antibodies in a biological sample, the sample is reacted in a reaction mixture which contains (i) a TSH-receptor or TSH-receptor preparation; (ii) a primary competitor, for example labelled TSH; and (iii) an agent for separating a complex composed of the TSH-receptor and the elements bound thereto of the reaction mixture from the liquid phase. According to the invention, the reaction is carried out in the presence of at least one monoclonal or polyclonal antibody specific against a partial peptide sequence of the TSH-receptor. This specific antibody is used to immobilise a complex of TSH-receptor and primary competitor and/or as secondary competitor for another part of the TSH-receptor auto-antibodies expected in a sample. The primary or secondary competitors are or can be selectively labelled.
