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 AChR antibody test measures autoantibodies directed against acetylcholine receptors, the proteins that receive nerve signals at the neuromuscular junction. Because these antibodies are present in a large majority of people with MG, the test serves as a key laboratory tool in the diagnostic process.
About Myasthenia Gravis (MG) Lab Test | AChR Antibody Testing in Rahway
Acetylcholine receptor (AChR) antibodies are autoantibodies that target the receptor proteins responsible for transmitting nerve impulses to muscles.
In Myasthenia Gravis, the immune system mistakenly produces antibodies against components of the neuromuscular junction. AChR binding antibodies attach to acetylcholine receptors and contribute to receptor loss or dysfunction, which impairs signal transmission and produces the characteristic muscle weakness.
The AChR antibody test detects and measures these binding antibodies in the blood. Binding antibodies are found in roughly 85 to 90 percent of individuals with generalized MG. A positive result supports the diagnosis of MG, though test results are interpreted alongside clinical findings and other evaluations.
A negative AChR antibody result does not entirely exclude MG. Some individuals with MG have antibodies to other neuromuscular junction targets, such as MuSK or LRP4, and a subset remains antibody-negative. For this reason, AChR antibody testing is one component of a broader diagnostic assessment rather than a standalone confirmation.
