Adenovirus antigens of various subtypes occur in patients with suspected viral gastroenteritis, lower respiratory infection, conjunctivitis or other infections. Sensitivity varies by site and subtype. A combined diagnostic approach will yield best results. For rapid detection of respiratory Adenovirus Ag, a respiratory swab is preferred for test code #2509 Adenovirus by DFA. For infant viral gastroenteritis, a stool swab in M4 transport media is preferred for test code #2410 Viral Culture.

1. Source of specimen is required, please include on requisition.
2. Specimens should be collected early in the acute phase of
infection. The chance of viral recovery is best during the first 3
days after onset and is greatly reduced beyond 5 days with many
viruses.
3. Submit 8 acetone-fixed slides or specimens in viral transport
media. Acceptable specimens: Nasopharyngeal swab/washings/aspirate,
bronchial lavage.
4. Unacceptable specimens:
Throat swabs on patients less than 2 years of age, non-respiratory
sites, specimen in nucleic acid transport system, dry swabs,
wooden or calcium alginate swabs, samples received ambient
or frozen at -20 degrees C.
5. Specimens received more than 72 hours from time of
draw must be frozen at -70C or on dry ice. Do not freeze
at -20 C. Virus loses infectivity.
6. Ship specimens on cold pack or on dry ice.
7. Viral transport media and dacron-tipped swabs with plastic
or fine-wire shafts available for use are provided. Please call
Client Services, 800-421-4449 to request media.
