Rapid antigen test for adenovirus in children: Age and onset of symptoms are important

Enferm Infecc Microbiol Clin (Engl Ed). 2023 Dec;41(10):617-620. doi: 10.1016/j.eimce.2022.09.015. Epub 2023 Apr 17.


Introduction: Respiratory infection is the most common human adenovirus (HAdV) disease accounting for 7-8% of viral respiratory diseases in children less than 5 years. Differentiation of bacterial infections and viral infections is a common clinical problem.

Material and methods: One hundred oropharyngeal swabs obtained from October 2019 to November 2020 from patients attending the paediatric emergency room with suspicion of upper respiratory tract infection and negative results in influenza and RSV tests were included. Oropharyngeal swabs specimens were rapidly processed with STANDARD™ F Adeno Respi Ag FIA and the results were confirmed by RealStar® Adenovirus PCR Kit 1.0 (Altona diagnostics).

Results: STANDARD™ F Adeno Respi Ag FIA had sensitivity and specificity values of 71.93% and 100% respectively. The performance of the test was higher in samples from children younger than 24 months and taken less than 72h since the beginning of symptoms. In this subgroup the test had 88.8% sensitivity and 100% specificity.

Conclusion: STANDARD™ F Adeno Respi Ag FIA may improve the management of respiratory diseases in children younger than 24 months and less than 72h since the beginning of symptoms in paediatric emergency rooms.
