Reference Range
Adenovirus Ab < 1:8

Interpretive Criteria:
< 1:8 Antibody not detected
≥1:8 Antibody detected

Single titers of ≥ 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 fourfold or greater increase in titer between acute and convalescent specimens confirms the diagnosis.

Clinical Significance
Adenovirus causes respiratory tract infections, conjunctivitis, and diarrhea. Infections are most common in individuals who are immunocompromised and in young children.
