Acetyl Choline Receptor Ab (Serum)

ACETYLCHOLINE RECEPTOR ANTIBODY:

CLINICAL INFORMATION :

Acetylcholine is a chief neurotransmitter of the parasympathetic nervous system (a branch of the peripheral nervous system) that contracts smooth muscles, dilates blood vessels, increases bodily secretions, and slows the heart rate. Acetylcholine antibodies in the blood of patients with myasthenia gravis (MG) affect the signals of acetylcholine (from nerve to the muscle and between nerves in the brain) by blocking its receptors (antibodies bind to acetylcholine receptors).  The acetylcholine receptor antibody test is used to help diagnose myasthenia gravis (MG) and to distinguish it from other conditions that may cause similar symptoms such as chronic muscle fatigue and weakness.

Diseases caused due to positive anti-acetylcholine receptor antibodies are lupus, rheumatoid arthritis, liver disease, auto-immune hepatitis, Lambert-Eaton syndrome, small cell lung cancer, Grave’s disease, and immune-suppressive therapy. Symptoms of acetylcholine receptor antibodies are shortness of breath, trouble in normal speech, drooping of eyelids, an unsteady walk, weakness in the arms, legs, neck, and fingers.
