ACETYLCHOLINE RECEPTOR BLOCKING ABS

AChR blocking antibodies are a type of autoantibody that target the neurotransmitter binding sites in the body. These antibodies are sometimes the only marker present in a small percentage of people with myasthenia gravis, an autoimmune neuromuscular disorder that affects muscle strength.

Testing for AChR blocking autoantibodies can play an important role in confirming a diagnosis and guiding treatment for patients with suspected myasthenia gravis.
