2227. Myositis profile (BlotAnalisis)
Important information
Description
Myositis-specific autoantibodies target various proteins in skeletal muscle cells and contribute to the development of autoimmune myositis.
Testing for these antibodies is indicated when symptoms such as muscle pain and weakness, swelling, skin lesions, or recurrent fever occur.
The test is performed for the diagnosis and differential diagnosis of myositis (dermatomyositis, polymyositis, and myositis).
The test is usually performed as part of a panel that includes blood biochemistry, electrolyte testing, creatine kinase (CK), myoglobin, and antinuclear antibodies (ANA).
When and who needs the test?
- For screening for autoimmune myopathies in patients with muscle weakness, muscle pain, or elevated creatine kinase (CK) levels.
- For monitoring disease course and assessing treatment efficacy.
- For the differential diagnosis of different types of myositis and other autoimmune disorders.
Biological material
- Venous blood
