RDL’s MyoMarker™ Panels

Myositis autoantibodies have been shown to be highly specific for patients with Polymyositis, Dermatomyositis and overlap syndromes.

The idiopathic inflammatory myopathies (IIM) are a heterogeneous group of disorders characterized by muscle weakness resulting from chronic muscle inflammation of unknown cause. Patients with IIM have a variety of autoantibodies with various clinical utilities. One group of these autoantibodies which is found only in patients with myositis, is known as myositis specific autoantibodies (MSA). The myositis antibodies have been shown to be highly specific for patients with polymyositis, dermatomyositis and overlap.
