Specimen Type Describes the specimen type validated for testing

Serum

Ordering Guidance

Typically, physicians will order acetylcholine receptor (AChR) binding, blocking, and modulating antibodies. Mayo Clinic Laboratories' (MCL) tests are not named in that manner; instead these are offered as myasthenia gravis (MG) evaluations. MGMR / Myasthenia Gravis Evaluation with MuSK Reflex, Serum is the testing of choice in most cases.

 

AChR blocking antibody testing is no longer offered individually as it offers no added-value to the diagnosis and management of MG.

Specimen Required Defines the optimal specimen required to perform the test and the preferred volume to complete testing

Only orderable as part of a profile. For more information see:
