title: [Rapid diagnosis of influenza: a comparative evaluation of different methods].
abstract: The results of influenza diagnosis during the outbreak of 1985 are presented. Nasopharyngeal secretions from 94 patients were examined by virus isolation in chick embryos, fluorescent antibody technique (FAT). enzyme-immunoassay (EIA), and dot-blot hybridization method (DBHM). The virus was isolated in 28%, FAT was positive in 22%, EIA in 47% of the cases. Among 94 secretion specimens 40 were tested by DBHM. In this instance, virus was isolated in 37%, EIA was positive in 65%, and DBHM in 85% of the cases. It seems advisable to use EIA based on the detection of the type-specific antigen (matrix protein) and DBHM which identifies the serovariant of influenza virus.
