Lab Code
MYOAB2
Epic Name
Myositis Antibody Extended Screen Panel
Description
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.
