WebWhat Abnormal Results Mean. An abnormal result means acetylcholine receptor antibody has been found in your blood. It confirms the diagnosis of myasthenia gravis in people who have symptoms. Nearly one half of people with myasthenia gravis that is limited to their eye muscles (ocular myasthenia gravis) have this antibody in their blood. WebThis test measures the concentration of a substance called acetylcholine receptor (AChR) antibody in your blood. Acetylcholine is a chemical that helps muscles contract. It acts as a messenger between nerves and muscles. People who have myasthenia gravis (MG) often make an abnormal protein called acetylcholine receptor antibody.
