Antibodies against Emerging Viruses
Indirect Immunofluorescence Test
- Over the past years it has been observed that a number of new viruses ("emerging viruses") and other pathogens has spread worldwide, introducing since then unknown diseases into previously unaffected regions.
- EUROIMMUN offers a broad spectrum of indirect immunofluorescence tests for the detection of specific antibodies (see table).
- Many of these substrates are available as single substrate with non-infected cells or as useful combinations (syndrome or geographically orientated) for the investigation of serum samples.
- IgG absorption as preparatory step for the determination of specific antibodies of class IgM: page 58.
- Cross reactions within the virus family, especially with Flaviviruses, should be taken into consideration since they may cause false-positive results. The infectious agent can be determined by titration of the sample and comparison of titers.
