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 is a key diagnostic tool, detecting autoantibodies against acetylcholine receptors that are present in a majority of MG cases. This test helps clinicians confirm a diagnosis and guide patient care.
About Myasthenia Gravis (MG) Lab Test | AChR Antibody Testing in Pullman
The AChR antibody test is central to the evaluation of Myasthenia Gravis.
Acetylcholine receptors (AChRs) are proteins on the surface of muscle cells that receive signals from nerve endings to trigger muscle contraction. In Myasthenia Gravis, the immune system mistakenly produces antibodies that bind to these receptors, impairing signal transmission and causing muscle weakness.
The AChR antibody test measures the level of these autoantibodies in the blood. A positive result supports a diagnosis of MG, especially when combined with clinical symptoms. However, a negative result does not rule out MG, as some patients may have other antibody types or no detectable antibodies.
Testing for AChR antibodies is typically ordered when a patient presents with symptoms such as drooping eyelids, double vision, difficulty swallowing, or generalized muscle weakness that worsens with activity. Early detection can lead to more effective management of the condition.
