This test measures antibodies against acetylcholine receptors in the blood, which are associated with autoimmune disorders like myasthenia gravis. The presence of these antibodies can disrupt nerve-to-muscle communication, causing muscle weakness, fatigue, and difficulty controlling facial or limb muscles. Blood analysis helps confirm diagnosis, guide treatment planning, and monitor disease progression. Patients benefit by understanding the cause of their symptoms, enabling timely therapy and management strategies to improve muscle strength and daily functioning. Early detection allows healthcare providers to implement treatments that reduce symptom severity and prevent complications, supporting long-term health and quality of life.
