The CD Acetylcholine Receptor Autoantibody (AChRAb) ELISA kit is intended for use by professional persons only, for the quantitative determination of AChRAb in human serum. Autoantibodies to the acetylcholine receptor (AChR) are responsible for failure of the neuromuscular junction in myasthenia gravis. Measurement of these antibodies can be of considerable value in disease diagnosis and management.
