[Comparative diagnostic value of laboratory tests in infectious allergic myocarditis]

A comparative assessment of a series of laboratory tests has been made in 206 patients with infectious-allergic myocarditis. Routine laboratory parameters were shown to be of little informative value. Neutrophil alkaline phosphatase activity, the index of neutrophil damage with respect to soluble cardiac antigen, basophil and eosinophil degranulation, and absolute blood basophil and eosinophil quantity were found to be the most meaningful criteria for the assessment of the activity of inflammatory and allergic processes in patients with infectious-allergic myocarditis.
