[ELISA in the rapid diagnosis of influenza using as the detecting antibodies polyclonal antinucleoprotein sera]

Hyperimmune polyclonal sera were obtained in order to use them as capture and detecting antibodies in rapid diagnostic of influenza A and B viruses by ELISA. The test shown 100% specificity. The sensitivity in directly detection of influenza viruses in human samples compared of influenza isolations was 49,25% for type A and 53,33% for type B. The sensitivity was increased after 48 hours from inoculation of human samples in cell culture-86,75% for type A detection and 80,0% for type B detection from supernatant mammalian tissue culture (MDCK).
