• One clinician uses troponin, NT-proBNP and creatine kinase to assess cardiac function in those with myocarditis. • One clinician includes lipids and electrolytes. • Another includes urine cultures, fibrinogen serum, and the Systemic or modified Systemic score to assess disease activity: “Fibrinogen serum level is useful with ESR because if both are elevated it shows a true inflammatory cause, otherwise ESR can be high for many reasons (e.g., anemia or high cholesterol serum levels).” The gene discussed is NPPB; the disease is myocarditis.
