Description
Why It’s Done:
The Parainfluenza IgG – EIA test is typically ordered for:
• Confirming past parainfluenza virus infection or exposure.
• Assessing immunity to parainfluenza in individuals at risk (e.g., those undergoing organ transplants or chemotherapy).
• Differentiating between active and past infections: If IgM is not detectable, IgG levels may help in distinguishing past infections from current illness.
• Evaluating outbreaks: In settings like hospitals or daycare centers, to understand the spread of parainfluenza viruses.
Preparation:
• No special preparation is typically required for this test.
• Fasting is generally not necessary for an IgG EIA test.
• If you are on any immunosuppressive therapy or have recently received a vaccination, inform your doctor, as this may affect the results of the test.
• This test involves a blood sample, typically collected via a routine blood draw.
