Reference Values

Reference Range:   <1:8

 

<1:8         Antibody not detected

≥ 1:8 Antibody Detected

 

INTERPRETIVE CRITERIA:

<1:8         Antibody not detected

≥ 1:8 Antibody Detected

 

 

Single titers ≥ 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.
