Enzyme Immunoassay (EIA)
The presence of IgM class antibodies indicates recent infection. The presence of IgG antibodies only is indicative of past exposure. Both IgG and IgM may be present at or soon after onset of illness and reach peak titers within 30 days. Because IgG antibody may persist for years, diagnosis of acute infection is made by the detection of IgM antibodies.
IgG:Negative; IgM: Negative

Collect specimen in SST (preferred) or red top tube (acceptable). Centrifuge, aliquot serum into a plastic vial and refrigerate.
The prevalence of parvovirus B19 IgG antibodies increases with age. The age-specific prevalence of antibodies to parvovirus is 2-9% of children under 5 years, 15% to 35% in children 5 to 18 years of age, and 30% to 60% in adults (19 years or older). Test sent to Mayo Medical Laboratories.
