Diagnostic value of the rapid influenza antigen test for novel influenza A (H1N1).
Summary of "Diagnostic value of the rapid influenza antigen test for novel influenza A (H1N1)."
Abstract We administered both the rapid antigen test and real-time reverse transcriptase polymerase chain reaction (RT-PCR) test to 2154 patients in order to assess the diagnostic value of the rapid antigen test during Korean pandemics of H1N1 2009. The overall sensitivity was 70.0%, specificity was 97.5%, positive predictive value was 97.4%, and negative predictive value was 71.2%. The sensitivity fell and the negative predictive value decreased as the RT-PCR positive rate increased.

Medical and Biotech [MESH] Definitions
Influenza B Virus
Species of the genus INFLUENZAVIRUS B that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.
Hemagglutinin Glycoproteins, Influenza Virus
Membrane glycoproteins from influenza viruses which are involved in hemagglutination, virus attachment, and envelope fusion. Fourteen distinct subtypes of HA glycoproteins and nine of NA glycoproteins have been identified from INFLUENZA A VIRUS; no subtypes have been identified for Influenza B or Influenza C viruses.
Influenza In Birds
Infection of domestic and wild fowl and other BIRDS with INFLUENZA A VIRUS. Avian influenza usually does not sicken birds, but can be highly pathogenic and fatal in domestic POULTRY.
Hla-a2 Antigen
Human histocompatibility (HLA) surface antigen encoded by the A locus on chromosome 6. The HLA-A2 antigen is associated with recognition of the INFLUENZA A VIRUS.
Influenzavirus C
A genus of the family ORTHOMYXOVIRIDAE comprising viruses similar to types A and B but less common, more stable, more homogeneous, and lacking the neuraminidase protein. They have not been associated with epidemics but may cause mild influenza. Influenza C virus is the type species.
