Acetylcholine Receptor (AChR) Blocking Antibody

Test Code : 83515

Ref. Range : <15% of inhibition

Clinical Significance
Myasthenia gravis (MG) is a neuromuscular disorder charactarized
by muscle weakness, most commonly due to autoantibody-mediated
loss of functional acetylcholine receptors (AChr) in the neuromuscular
junction.  This assay is most useful when the acetylcholinesterase
receptor modulating antibodies are positive.  The assay for blocking
antibodies is useful in monitoring response to therapy.
