14.3.2 Cell Culture Confirmation<br />
Three trial centres tested the IMAGEN <strong>Adenovirus</strong> test on cell cultures from clinical specimens. This was<br />
compared against indirect immunofluorescence and/or neutralisation tests for culture confirmation.<br />
Isolations were made in routine cell lines used for adenovirus culture. Cell cultures were washed in PBS<br />
before being removed and spotted on to slides. The slides were fixed in acetone and then tested using the<br />
IMAGEN <strong>Adenovirus</strong> test reagents. Both fresh clinical isolates and previously frozen specimens were<br />
used for this evaluation. A total of 296 cultures were evaluated. Cell culture positive isolates were confirmed<br />
by either immunofluorescence or neutralisation tests.<br />
The results (Table 14.3) indicate that the IMAGEN <strong>Adenovirus</strong> test detected all positive adenovirus<br />
isolates giving a sensitivity of 100% (162/162). The specificity of the reagent was 100% (134/134).<br />

14.4 CROSS-REACTIVITY<br />
The IMAGEN <strong>Adenovirus</strong> test was performed against preparations of other viruses and organisms likely<br />
to be present in respiratory or ophthalmic specimens or cell cultures. All organisms tested (Table 14.4) were<br />
negative with the IMAGEN <strong>Adenovirus</strong> test.<br />
