Testing Algorithm

All routine viral cultures are inoculated into cell culture tubes for viral detection. The most common specimens received for routine testing include bronchoalveolar lavage, sputum, and throat. A rapid (16-hour incubation) shell vial cell culture assay will be inoculated when specimens are designated for herpes simplex virus or cytomegalovirus detection or as appropriate for source indicated.


If enterovirus or hand, foot, and mouth disease is suspected, clearly indicate "enterovirus" on request.
