  • Title: Antigen detection in the diagnosis of viral infections.
    Author: Hietala J, Uhari M, Tuokko H.
    Journal: Scand J Infect Dis; 1988; 20(6):595-9. PubMed ID: 2851878.
    Abstract:
    The value of viral antigen detection from nasopharyngeal secretion (NPS) by enzyme immunoassay (EIA) in everyday clinical practice was evaluated in 570 children hospitalized because of infections. NPS-EIA gave a positive result in 32% of all cases. Virus isolation was positive in the NPS in 25%, virus isolation in stool samples in 14%, and virus serology in 28% of the cases. NPS-EIA was superior for detecting adenovirus, respiratory syncytial (RS) and parainfluenza viruses. In a series of 124 patients in whom 3 methods were compared, NPS-EIA was the only positive method in 48% of all findings positive for adenoviruses, in 73% for RSV, and in 58% for parainfluenza viruses. Antigen detection by NPS-EIA markedly increased the diagnostic potential in everyday clinical practice, especially for viral respiratory diseases.
