The battery MYOAB2 includes 15 different myositis related antibodies. Samples with Borderline or Positive results are confirmed with an alternate method.

Autoimmune forms of myositis are associated with a variety of autoantibodies. These antibodies have a low sensitivity, but high specificity for the condition. Screening for multiple antibodies increases the overall sensitivity of the testing.
