Order Myasthenia Gravis (MG) Lab Test | AChR Antibody TestingMyasthenia Gravis is an autoimmune disorder that disrupts communication between nerves and muscles, leading to weakness that worsens with activity and improves with rest. The acetylcholine receptor (AChR) antibody test is a blood test used to help identify this condition by detecting autoantibodies directed against the receptor that receives nerve signals at the neuromuscular junction.
About Myasthenia Gravis (MG) Lab Test | AChR Antibody Testing in Orange
The AChR antibody test measures autoantibodies that target the acetylcholine receptor, a protein essential for transmitting nerve impulses to muscle fibers.
In Myasthenia Gravis, the immune system mistakenly produces antibodies against proteins at the neuromuscular junction. Binding antibodies attach to the acetylcholine receptor and are the most commonly detected type, found in roughly 85 to 90 percent of people with generalized MG.
The test reports whether AChR binding antibodies are present and, when positive, provides a quantitative level. A positive result supports a diagnosis of MG but is interpreted alongside symptoms, physical examination, and sometimes additional antibody tests such as blocking or modulating antibodies.
A negative result does not rule out Myasthenia Gravis. Some people with MG have antibodies against other targets, such as muscle-specific kinase (MuSK) or LRP4, and a subset remains antibody-negative. Results should always be reviewed by a clinician in the context of the full clinical picture.
