| Additional information |
Clinical use is as an aid in the diagnosis of parvovirus infections. Results from any one IgM assay should not be used as a sole determinant of a current or recent infection. Because IgM tests can yield false positive results and low levels of IgM antibody may persist for months post infection, reliance on a single test result could be misleading. If an acute infection is suspected, obtain a new specimen and submit for both IgG and IgM testing in two or more weeks. IgG persists for years and provides life-long immunity. To diagnose current infection, the laboratory recommends Parvovirus, PCR test. |
