Test ID: FDFA    
Dengue Fever Antibodies (IgG, IgM)

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:    IgG   <0.90

                                         IgM  <0.90


These assays detect both IgG and IgM class antibodies against all

four Dengue fever virus types.  Except for very early IgM responses,

the immune response to Dengue fever is not type specific.  Therefore,

type specific reactions are not reported.  As with most serological

assays, paired testing of acute and convalescent samples is

preferred.  This is especially important when the acute phase

sample is taken within the first six days following onset.  In most

patients, Dengue antibodies are detectable after the sixth day

following the onset of symptoms.  Crossreactivity with other

flaviviruses is known to occur.  The extent and degree of

crossreaction varies.
