An acetylcholine receptor (AChR) antibody test is used to help diagnose myasthenia gravis (MG) and to distinguish it from other conditions that can cause similar symptoms, such as chronic muscle fatigue and weakness. Three types of AChR antibodies can be tested: Antibodies that bind to AChR. AChR blocking antibodies.
