Two types of parvovirus B19 antibodies may be produced in response to an infection: IgM and IgG. IgM antibodies are the first to be produced by the body in response to a parvovirus infection. They are present in most individuals within a week or two after the initial exposure. IgM antibody production rises for a short time period and then declines. Eventually, the level of parvovirus IgM antibody usually falls below detectable levels. IgG antibodies are produced by the body a few weeks after the initial infection to provide long-term protection. Levels of IgG rise during the active infection, then stabilize as the parvovirus B19 infection resolves. Once a person has been exposed to parvovirus B19, that person will have some measurable amount of IgG antibody in their blood for the rest of their lifetime.Parvovirus B19 antibody testing may be performed to determine immunity to parvovirus in pregnant women who have been exposed to someone with parvovirus B19 or who have symptoms suggestive of parvovirus infection. It may also be ordered for people who have acute or chronic anemia or persistent joint pain that may be due to a parvovirus B19 infection. By comparing the absence or presence of both IgG and IgM in the same sample, the health practitioner can distinguish between current, recent, and previous infections. Antibody testing is usually not performed on children who have the characteristic fifth disease rashes and, since parvovirus B19 infection is widespread and causes few problems to those with healthy immune systems, general population screening is rarely done.
