Acetylcholine Receptor (AChR) Antibody: Normal, High

Acetylcholine Receptor (AChR) Antibody Test measures the level of AChR antibody in the blood, in order to diagnose myasthenia gravis (MG).

Results and Meanings:

  • Normally, there should be no AChR antibody in the blood, or at least less than 0.05 nmol/L.
  • But, a normal/negative result only indicates that the person probably has no MG.
  • A high result combined with symptoms of MG indicates that the person is likely to have MG.


For more specific diagnosis, other tests for autoantibodies are needed.
