Adenovirus Antigen Detection, Gastroenteritis, EIA
Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
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.
