Parvovirus B19 IgG details
Description
This antibody indicates past exposure to parvovirus B19, the virus responsible for fifth disease (erythema infectiosum), a common, typically mild childhood illness causing a distinctive facial rash, though infection in adults can also cause joint pain. A positive IgG result indicates past infection and generally lifelong immunity. This is particularly relevant during pregnancy, since a new infection (rather than past immunity) carries a small risk of affecting the developing baby, which is why parvovirus testing is sometimes done if a pregnant woman is exposed or develops a suggestive rash or illness.
