|Additional information||For occupational or early post-exposure screening, a single specimen is generally sufficient to determine immunity to rubella infection. An EQUIVOCAL result may not provide sufficient protection from clinical illness upon exposure to rubella virus.
When congenital infection is suspected, an initial negative result most likely excludes the diagnosis. If the result is positive in the initial specimen, a second sample should be submitted 3 months later to distinguish transplacentally-transmitted maternal antibody from congenital infection.
See also entry for Rubella Culture and table for Viral Serology. Acute cases of rubella should show a rise in antibody from an initially negative or equivocal level.
