Test Overview

Test Methodology

Multiplex Flow Immunoassay

Test Usage

Support the diagnosis of measles or SSPE (sub-sclerosing pan ecephalitis) infection. The presence of IgG antibody generally indicates past exposure and immunity. The presence of IgM antibody or a fourfold or greater rise in IgG antibodies in paired sera indicates recent infection. Single IgG levels are not useful for supporting the diagnosis of an acute infection. Elevated levels in neonates should be followed up with studies to rule out the presence of maternal antibodies by demonstrating the absence of an IgM response.

Reference Range

NEGATIVE: No Rubeola IgG antibody detected; POSITIVE: Rubeola IgG Antibody detected, indicating previous exposure and immunity to Rubeola virus.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
