Order Myasthenia Gravis (MG) Lab Test | AChR Antibody TestingMyasthenia Gravis is an autoimmune disorder in which the body's immune system interferes with communication between nerves and muscles. The acetylcholine receptor (AChR) antibody test is a blood test that measures autoantibodies directed against the acetylcholine receptor, a protein that helps transmit signals at the neuromuscular junction.
About Myasthenia Gravis (MG) Lab Test | AChR Antibody Testing in Davis
The AChR antibody test is a laboratory method used to support the diagnosis of Myasthenia Gravis by detecting autoantibodies that target the acetylcholine receptor.
Acetylcholine is a neurotransmitter released by nerve endings to activate muscle contraction. It binds to acetylcholine receptors on the muscle surface, completing the signal that leads to movement. In Myasthenia Gravis, autoantibodies attack these receptors or associated proteins, reducing the number of functional receptors and impairing neuromuscular transmission.
The most common form of testing detects AChR binding antibodies, which are present in roughly 85 to 90 percent of people with generalized Myasthenia Gravis. Other antibody types, such as blocking and modulating antibodies, may also be evaluated in certain situations. A positive result supports the diagnosis, but results are interpreted alongside clinical findings and other tests.
Because antibody levels do not always match symptom severity, the test is not used to monitor disease progression or response to treatment. Some individuals with Myasthenia Gravis may test negative for AChR antibodies, and other antibody tests or clinical evaluation may be needed.
