  • Biopsy of the skin where a sample of the skin from the affected area is taken and sent to lab for testing.
  • Serologic tests are done to help identify the cause of heliotrope rash. Serologic testing done for myositis-specific antibodies is helpful.
  • Enzymatic testing comprising of estimation of creatine kinase, alanine aminotransferase, lactic dehydrogenase or aldolase is done. The increased level of lactic dehydrogenase and creatine kinase helps in diagnosis.
  • Von Willebrand factor detection is done for diagnosing Juvenile Dermatomyositis (JDM).

The below tests are done to assess the severity of the condition and include:

  • Chest x-ray and pulmonary function test is done to check if there is lung involvement.
