Description
Why It’s Done:
The Parvo Virus B19 – IgM test is commonly ordered to:
• Diagnose recent Parvovirus B19 infection, particularly in patients with flu-like symptoms, rash, or joint pain.
• Evaluate symptoms in pregnant women who may have been exposed to the virus, as Parvovirus B19 infection during pregnancy can lead to serious fetal complications like hydrops fetalis, anemia, or miscarriage.
• Assess unexplained anemia or aplastic crisis, especially in individuals with sickle cell disease or other chronic hemolytic anemias.
• Investigate suspected outbreaks in schools, daycares, or healthcare settings.
• Help differentiate between acute and past infection when combined with Parvovirus B19 IgG testing.
Preparation:
• No special preparation is usually needed.
• Fasting is not required for this test.
• Inform your healthcare provider if you are pregnant, immunocompromised, or have recent symptoms like rash, fever, or fatigue.
• A blood sample will be collected from a vein in your arm for analysis.
