Reference Range:
|

|
Limitations:
|
Grossly contaminated, hemolyzed, hyperlipemic, or icteric serum may yield unreliable results. Serum specimens must not be heat-inactivated prior to testing.
A serum specimen drawn during the acute phase of infection when only low titers of IgM are present may yield negative results by this procedure.
Rare heterotypic responses with rubella virus and varicella virus have been reported from measles virus.
