Clinical Info

The current echovirus panel includes serotypes 4, 7, 9, 11, and 30. The echovirus serotypes used in this panel will vary depending upon current epidemiological data available from inhouse isolations CDC reports. Generally, the serotypes used are those most commonly associated with viral meningitis.

Result Interpretation

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 and 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.
