Parvovirus B19 Antibody, IgM, Serum
Use
This test is useful for the serologic detection of recent or past parvovirus B19 infection using IgM antibodies. Parvovirus B19 is the causative agent of fifth disease, characterized by an intensive erythematous facial rash. It is primarily acquired by direct contact with respiratory secretions. The virus has been associated with fetal damage and arthralgia, and infection during pregnancy may cause severe complications for the fetus.
Special Instructions
The test is orderable only as part of a profile, specifically in combination with Parvovirus B19 Antibodies, IgG and IgM, Serum. The collection requires serum gel as the preferred container or red top as acceptable. Centrifuge and aliquot serum into a plastic vial for submission.
Limitations
The test is not useful as a screening procedure for the general population. Specimens containing antinuclear antibodies or those from immunocompromised patients may produce equivocal or positive results in the IgM assay. Assay performance has not been established for neonates or for matrices other than serum.
