Laboratory findings consistent with the diagnosis of myocarditis include elevated markers of myonecrosis, inflammatory markers, and other biomarkers. Markers of myonecrosis include creatine kinase (CK-MB), cardiac troponin I (cTnI) or T (cTnT), lactate dehydrogenase (LDH), alanine transaminase (ALT), and aspartate transaminase (AST).  Elevated levels of C-reactive protein and erythrocyte sedimentation rate (ESR), and leukocytosis are suggestive of myocarditis. Serologic markers such as Fas, Fas ligand, interleukin-10 or antimyosin autoantibodies are of prognostic value in myocarditis.  Other auto-antibodies such as ANA and rheumatoid factor may also be detected.
