What is a confirmatory assay?
Confirmatory Assays are used to confirm whether specimens found reactive with a particular screening test contain antibodies specific to the virus they have been tested for.
- Expensive tests, first generation tests have proven to be prone to producing large numbers of indeterminate results.
- LIAs ( Line immune-assays ) have been developed which in general produce fewer indeterminate results.
- Studies have shown that combinations of ELISAs or Simple/Rapid assays can provide results as reliable as the confirmatory assays at a much lower cost.
