Clinical Significance

Adenovirus causes respiratory tract infections, conjunctivitis, and diarrhea. Infections are most common in individuals who are immunocompromised and in young children. Adenovirus antigen detection is useful to confirm the diagnosis of adenovirus infection in patients with respiratory illness.


Specimen Collection & Preparation

Specimen Requirements

3 mL of nasopharyngeal aspirate/wash, bronchial lavage/wash, throat swab, conjunctival swab or nasal/nasopharyngeal swab in VCM medium (green-cap) tube 

Alternate Specimen

Specimen on 2 air-dried slides • Raw (unpreserved) sample in sterile screw-cap container

Collection Instructions

To maintain optimum viability, place swab or fluid into VCM (equal volumes of fluid and VCM) or equivalent and transport the specimen to the laboratory as soon as possible. Best recovery is obtained when the specimens are refrigerated at 2-8° C or kept on wet ice following collection and while in transit. If there will be a long delay before processing, specimens in VCM or equivalent should be frozen at -70° C or colder and transported on dry ice.
