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.
