Adenovirus Antibody, Serum
Reference Values:
Reference Range: or =1:64 are indicative of recent or current
infection. Titers of 1:8-1:32 may be indicative of either past or
recent infection, since CF antibody levels persist for only a few
months. A four-fold or greater increase in titer between acute and
convalescent specimens confirms the diagnosis.

Adenovirus Antigen Detection, Gastroenteritis, EIA
Reference Values:
Not Detected
A positive test result in association with diarrhea highly suggests that Adenovirus is the cause of the
gastroenteritis. Adenovirus may shed asymptomatically up to 18 months after infection. The virus may
also become latent, then reactivate. If the patient, in fact, has a bacterial enterocolitis due to
Staphylococcus aureus, high levels of the bacterial protein A may cross-react with this test and result in a
false positive.
