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.
