Order Myasthenia Gravis (MG) Lab Test | AChR Antibody TestingMyasthenia Gravis (MG) is an autoimmune disorder that disrupts communication between nerves and muscles, leading to weakness and fatigue. The acetylcholine receptor (AChR) antibody test is a key laboratory tool used to support the diagnosis of MG by detecting autoantibodies that target the AChR at the neuromuscular junction.
About Myasthenia Gravis (MG) Lab Test | AChR Antibody Testing in St. Augustine
The AChR antibody test measures autoantibodies directed against the acetylcholine receptor, a protein essential for transmitting nerve signals to muscles.
In Myasthenia Gravis, the immune system mistakenly produces antibodies that bind to the acetylcholine receptor, impairing neuromuscular transmission and causing characteristic muscle weakness.
The test specifically detects binding antibodies to the AChR. These antibodies are present in approximately 85 to 90 percent of individuals with generalized MG, making the test a valuable diagnostic marker.
A positive result supports the diagnosis of MG, but it is interpreted alongside clinical symptoms and other evaluations. A negative result does not entirely exclude MG, as some patients may have antibodies to other components of the neuromuscular junction.
