CMV IgG Avidity Elecsys | REF 5909708190

The Roche CMV IgG Avidity Elecsys assay (REF 5909708190) is an in vitro diagnostic reagent kit designed for the qualitative determination of the avidity of IgG antibodies to cytomegalovirus (CMV) in human serum and plasma. The test is performed on Roche Elecsys and cobas e immunoassay analyzers using electrochemiluminescence immunoassay (ECLIA) technology, providing laboratories with a tool to help differentiate recent from past CMV infections.

Key Features
- Methodology: Electrochemiluminescence immunoassay (ECLIA) on Roche Elecsys / cobas e platforms.
- Application: Determination of CMV IgG antibody avidity to support timing of infection assessment.
- Sample types: Human serum and plasma as defined by the manufacturer's instructions for use.
- Format: Ready-to-use Elecsys reagent rackpack compatible with Roche cobas immunoassay modules.
- Workflow: Automated processing with consolidated reporting alongside other Elecsys infectious disease assays.
- Traceability: Barcoded reagent cassettes for lot tracking and onboard identification.

Clinical Applications
- Maternal screening support: Used as part of laboratory workups assessing CMV serostatus, particularly relevant in prenatal evaluation workflows.
- Infection timing: Avidity index results aid laboratories in distinguishing primary from past CMV infection in IgG-positive individuals.
- Reflex testing: Suitable as a follow-up assay after positive CMV IgG and/or IgM screening results.
- Reference and hospital laboratories: Supports virology and serology testing menus on consolidated Roche immunoassay platforms.
