At a Glance

Why Get Tested?

To determine if you have, or recently had, a parvovirus B19 infection if you are at increased risk of complications from this viral infection; if a fetus is at high risk of contracting parvovirus B19 from a mother who is infected or has been exposed

When to Get Tested?

When a pregnant woman has a parvovirus B19 infection or has been exposed to someone with the virus; when someone, especially an immune-compromised person, has persistent or severe anemia

Sample Required?

A blood sample drawn from a vein in your arm for parvovirus B19 antibody testing; to detect the virus itself, the sample tested may be blood or, rarely, bone marrow; in certain cases, fetal cord blood or amniotic fluid may be collected to test for fetal parvovirus B19 infection.
