• Acute viral symptoms: fever, sore throat or general malaise.
• Post-viral symptoms: ongoing fatigue following a viral illness.
• Suspected enterovirus exposure: symptoms following contact with infected individuals.
• Neurological symptoms: headache or neck stiffness suggestive of meningitis.
• Cardiac symptoms: chest pain, palpitations or suspected myocarditis or pericarditis.
• Paediatric viral illness: symptoms consistent with hand, foot and mouth disease.
• Recurrent infections: repeated viral-type illnesses without clear cause.
• Immune assessment: evaluation of recent versus past exposure to Coxsackievirus.

Overview

The Coxsackievirus Antibodies test measures IgG and IgM antibodies to Coxsackievirus using a venous blood sample. Coxsackieviruses are enteroviruses, and antibody testing assesses the humoral immune response, with IgM typically associated with more recent exposure and IgG reflecting past exposure.

Clinically, this test may be useful when individuals present with symptoms suggestive of enteroviral infection or when there is a need to distinguish between recent and previous exposure. Antibody testing can provide complementary information to cellular immune assessments such as EliSpot, particularly in individuals who produce detectable antibodies.

Practitioners typically interpret results alongside symptom history, timing of illness, immune status and other laboratory findings. When reviewed in context, the test can support informed discussions with clients about immune responses to Coxsackievirus and patterns of exposure.
