Description
Why It’s Done
The Echovirus Antibodies Panel (IgG, IgM) test is typically performed to:
• Diagnose recent or past echovirus infections in patients presenting with symptoms such as:
o Fever, headache, or neck stiffness (suggestive of aseptic meningitis)
o Gastrointestinal symptoms like diarrhea, nausea, or vomiting
o Skin rashes, hand, foot, and mouth disease
o Respiratory symptoms such as coughing or difficulty breathing
• Determine the stage of an infection:
o High levels of IgM antibodies indicate acute or recent infection.
o Presence of IgG antibodies indicates previous exposure or immunity.
• Monitor outbreaks of echovirus infections in communities or hospital settings, especially in pediatric populations.
• In immunocompromised patients to assess the presence of a latent or reactivated infection.
• Differentiate echovirus infections from other enterovirus-related illnesses, as the symptoms can overlap with other viral infections.
Preparation
• No special preparation is needed before the test.
• A blood sample will be drawn, typically from a vein in the arm.
• It’s helpful to inform the healthcare provider about any recent viral infections, travel history, or exposure to others with suspected enterovirus infections.
• The test is usually ordered based on symptoms or clinical suspicion, so providing a clear history of recent illness or contact with infected individuals is important for accurate interpretation.
