Test ID: ECHO    
Echovirus Antibody Panel, CF (Serum)

Available on the App Store

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Reference Range:   <1:8


<1:8  Antibody not detected

> or = 1:8 Antibody Detected



<1:8  Antibody not detected

> or = 1:8 Antibody Detected



Single titers > or = 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.


This test was developed and its performance characteristics

have been determined by Focus Diagnostics. Performance
