The Copalis™ TORC Total Antibody Assay uses Coupled Particle Light Scattering (Copalis™) technology in a microparticle agglutination-based immunoassay for the qualitative detection of total antibodies (IgG and IgM) to Toxoplasma gondii, rubella and cytomegalovirus (CMV) in human serum using the Copalis™ One Immunoassay System. The presence of antibodies is indicative of current or prior infection with the suspected organism. The results of this assay on a single serum specimen are used to determine the patient’s immune status for rubella and to determine the patient’s immunological experience for Toxoplasma gondii and CMV. When evaluating properly paired sera, the results of this assay are used to demonstrate seroconversion as evidence of recent infection. Both specimens should be tested simultaneously (see Interpretation of Results). This assay has not been FDA cleared or approved for the screening of blood or plasma donors.
