Acetylcholine Receptor Modulating Antibody Test

The Acetylcholine Receptor Modulating Antibody Test measures autoantibodies that cause loss or alteration of acetylcholine receptors on muscle cells, impairing nerve transmission. Elevated levels are commonly linked to myasthenia gravis, an autoimmune disorder causing muscle weakness. This test aids in identifying immune-mediated neuromuscular disease and helps evaluate disease severity.

The Acetylcholine Receptor Modulating Antibody Test test contains 1 test with 1 biomarker .

Myasthenia gravis (MG) is a neuromuscular disorder characterized by muscle weakness, most commonly due to autoantibody-mediated loss of functional acetylcholine receptors (AChR) in the neuromuscular junction. Modulating Antibody to AChR causes weakness by inhibiting or modulating binding to the receptors.
