Test ID: FENT    
Enterovirus Panel II, CF (Serum)

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

 

INTERPRETIVE CRITERIA for Coxsackie A, B and Echovirus:

< 1:8  Antibody Not Detected

> or = 1:8 Antibody Detected

 

Single titers > or = 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.

 

INTERPRETIVE CRITERIA for Poliovirus:

< 1:8 Antibody Not Detected

> or = 1:8 Antibody Detected

 

Because CF antibody levels usually persist for only a few months,

any measurable titer may indicate recent exposure.  Single titers

 > or = 1:32 provide strong evidence for recent exposure.  A four-fold

or greater increase in titer between acute and convalescent specimens

confirms recent exposure or infection.
