Description
Why It’s Done:
The Parvo Virus B19 – IgG Test is typically ordered to:
• Confirm past exposure to Parvovirus B19, particularly in individuals who may have symptoms of fifth disease or in those who have been in contact with someone who has the infection.
• Assess immunity in pregnant women, as Parvovirus B19 infection during pregnancy can lead to complications like miscarriage, stillbirth, or hydrops fetalis (a serious condition involving fluid buildup in a fetus).
• Diagnose prior infection in individuals with suspected parvovirus B19 exposure or a history of symptoms (e.g., rash or joint pain).
• Evaluate risk in immunocompromised individuals who may be more susceptible to the virus and its effects.
Preparation:
• No special preparation is usually required for this test.
• Fasting is not necessary for a Parvo Virus B19 – IgG test.
• Inform your doctor if you have any recent symptoms of Parvovirus B19, or if you are pregnant, as the test results may impact the monitoring or management of the pregnancy.
• A blood sample will be drawn from a vein in your arm for testing.
