About The Test

How is it used
AChR antibodies block the acetylcholine action. acetylcholine is a neurotransmitter that transmits messages between nerve cells The AChR antibodies function by blocking, binding and modulating. There are three different types of tests available to determine which of these may be the problem. One or more of the AChR antibody tests may be done along with a striated muscle antibody test to establish a diagnosis. an anti-muscle-specific kinase antibody test may also be done depending on the results. MG patients often have an enlarged thymus gland or thymomas. The thymus gland is located under the breastbone and is an active part of the immune system.
