Clinical Information
Human adenoviruses cause a variety of diseases, including pneumonia, cystitis, conjunctivitis, diarrhea, hepatitis, myocarditis, and encephalitis. In humans, adenoviruses have been recovered from almost every organ system. Infections can occur at any time of the year and in all age groups. Currently, there are over 50 adenovirus serotypes that have been grouped into 6 separate subgenera.
Although adenovirus can be recovered in cell culture, it can take up to 3 weeks for the virus to be identified by culture methods (Mayo Clinic's shell vial culture provides more rapid results, reported at 2 and 5 days). Serological tests have faster turnaround times but can be less sensitive compared to culture. Polymerase chain reaction assays offer a rapid, specific, and sensitive means of diagnosis by detecting adenovirus DNA.
Interpretation
A positive result indicates the presence of adenovirus DNA in the clinical specimen.
A negative result does not rule out the presence of adenovirus because viral DNA may be present at levels below the detection limits of this assay.
