High acetylcholine receptor antibodies

WebWe found high anti-AChR levels in 2 out of 11 thymoma patients without MG, while 37 out of 250 MG patients had no detectable anti-AChR. The absence of these antibodies was related to purely ocular disease and to steroid therapy and/or thymectomy. WebAcetylcholine receptor antibodies are the main pathogenic agent in myasthenia gravis, a neurological disorder resulting in weakness and fatigability of voluntary muscles. The antibodies can be measured by a radioimmunoprecipitation assay, which is in use throughout the world and provides a diagnostic test of high sensitivity and specificity.
