Adenovirus PCRUseful For
Aiding in the diagnosis of adenovirus infections
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 57 adenovirus serotypes that have been grouped into 6 separate subgenera.
Culture is the gold standard for the diagnosis for adenovirus infection. However, it can take up to 3 weeks to achieve culture results (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. PCR offers 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 sample.
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.
