Title: Swabbing for respiratory viral infections in older patients: a comparison of rayon and nylon flocked swabs Document date: 2010_9_18
ID: ivu632j2_34
Snippet: In terms of CT, we found nasopharyngeal samples to be superior to oropharyngeal samples, yielding a calculated 19 times higher concentration of viral nucleic acids. This corresponds to the results found in a study by Lieberman et al. [16] , with a much broader variation in patient age. Our subgroup analysis of influenza A virus reveals a calculated 286 times higher viral load in samples from the nasopharynx. As shown in Table 3 , several samples .....

This corresponds to the results found in a study by Lieberman et al. [16] , with a much broader variation in patient age. Our subgroup analysis of influenza A virus reveals a calculated 286 times higher viral load in samples from the nasopharynx. As shown in Table 3 , several samples were negative for influenza A virus in the oropharynx and positive in the nasopharynx.
