Test Name: Acetylcholine Receptor (AChR) Blocking Antibody
Test Method: Enzyme Immunoassay
Test Principle: This test measures the presence and level of antibodies that can block the acetylcholine receptors in the body. These antibodies are commonly associated with autoimmune disorders such as Myasthenia Gravis.
Metabolism or Outline: The test measures the ability of the patient’s serum to block the binding of acetylcholine to the acetylcholine receptors. The more antibodies present in the serum, the greater the blocking effect on the receptors.
Primary Sample(s): Serum
