Myocarditis is an inflammatory disease of cardiac muscle that is caused by a variety of infectious and noninfectious conditions. It can be an acute, subacute, or chronic disorder, and may present with focal or diffuse involvement of the myocardium. Myocarditis can be produced by a variety of infectious and noninfectious causes. In addition, many inherited cardiomyopathies (eg, Fabry disease and arrhythmogenic right ventricular cardiomyopathy) may present with features of acute or chronic myocarditis.
The frequency of myocarditis and its specific causes have not been well defined; the clinical presentation is too variable and there is no accurate and simple test that can be used confirm the diagnosis or cause.
Myocarditis can be caused by a variety of infectious and noninfectious illnesses. Among the infectious etiologies, viruses are the presumed to be the most frequent pathogens, but bacteria, fungi, protozoa, and helminths can also cause myocarditis.
Microbiology - Virology
Testing is batched daily Monday-Friday at approximately 9.30am, with results available from mid-afternoon. Urgent or weekend testing must be discussed with and approved by a Microbiologist
Myocarditis panel - PCR
Myocarditis screen - PCR
See constituent tests
Specimens of choice are pericardial fluid or myocardial tissue. Other specimens may be processed after discussion with a Microbiologist.
Chilled (2 - 8 degrees Celsius)
Place sample in PCR bag.
Nucleic acid extraction, qualitative PCR amplification and detection.
On receipt, sample will be tested for SARS-CoV-2 and the Respiratory Multiplex panel (specifically for Influenza, Adenovirus and Enterovirus targets).
After discussion with the Microbiologist, further testing for Parvovirus, CMV, EBV and/or HHV6 can be performed.
