Test Details

Methodology

Immunoassay (IA)

Reference Range(s)

Value	Interpretation
0.00-0.90	Negative
0.91-1.09	Equivocal
≥1.10	Positive

Results from any one IgM assay should not be used as a sole determinant of a current or recent infection. Because an IgM test can yield false positive results and low levels of IgM antibody may persist for more than 12 months post infection, reliance on a single test result could be misleading. If an acute infection is suspected, consider obtaining a new specimen and submit for both IgG and IgM testing in two or more weeks.
