“…The two-tier antibody-based test recommended by the CDC is highly specific but has poor sensitivity [59]. Supplementary studies that have been used in the diagnosis include echocardiography [7, 57, 60], gadolinium enhanced cardiac MRI [16, 27], endo-myocardial biopsy [6, 7, 22, 61, 62] with special staining [3, 4, 8, 40], culture [3] or electron microscopy [7, 61–63], Ga67 Scan [64–66], and Indium 111 labelled anti-myosin antibody scintigraphy [4]. Histology of affected cardiac tissue shows infiltration predominantly with lymphocytes and plasma cells [15, 22, 29, 40].…”
