Index Value

Result

Interpretation

 < 0.90 Index

Negative

Sample is considered negative for IgG antibodies to rubella virus.  A negative result presumes that immunity has not been acquired.  If exposure to rubella virus is suspected despite a negative finding, a second specimen should be collected and tested one or two weeks later.  Seroconversion from a negative specimen to a positive specimen is evidence of either recent infection, response to vaccination, or administration of immunoglobulins.
