AChR (Acetyl Choline Receptor) Antibodies

Understanding AChR (Acetyl Choline Receptor) Antibodies

Acetylcholine is a neurotransmitter that is responsible for initiating muscle contraction by sending signals from nerves to muscles. In individuals with myasthenia gravis (MG), the immune system creates abnormal proteins called acetylcholine receptor antibodies, which interfere with normal acetylcholine function. MG is an autoimmune disorder, since the body mistakenly attacks its own communication networks between muscles and nerves, leading to fluctuating muscle weakness.

Although MG is rare, it can affect indivi...

What does AChR (Acetyl Choline Receptor) Antibodies measure?

The AChR (Acetyl Choline Receptor) Antibodies test is a blood test that helps diagnose myasthenia gravis (MG), a chronic autoimmune neuromuscular disease, and distinguish it from other neuromuscular disorders. It measures the levels of acetylcholine receptor (AChR) antibodies in individuals with MG.
