Reference Values

REFERENCE RANGE: <1:8

 

INTERPRETIVE CRITERIA:     

                     <1:8  Antibody Not Detected

            ≥ 1:8  Antibody Detected

 

Single titers of ≥ 1:32 are indicative of recent infection. Titers of 1:8 or 1:16 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. There is considerable crossreactivity among enteroviruses; however, the highest titer is usually associated with the infecting serotype.
