Auto-Antibodies in Juvenile Myositis

This presentation introduces you to Myositis Specific Antibodies or MSAs and addresses important questions, including the following:

How are MSAs tested, and what is their value?

How have myositis-specific antibodies improved our understanding of myositis by identifying clinical patterns that help doctors understand how the disease might progress in patients with certain MSAs?

What is the value of understanding MSAs to help further personalize treatment options that your clinical team may consider?
