Dengue Fever Virus Antibodies, IgG and IgM
Ordering Recommendation
May aid in the diagnosis of dengue when timing of infection is uncertain. Testing should also be considered for other arthropod-borne viruses with similar symptomology based on clinical presentation and travel history.
New York DOH Approval Status
Specimen Required
Serum separator tube.
Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.1 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimens plainly as "acute or convalescent."
Refrigerated.
Bacterially contaminated, heat-inactivated, hemolyzed, icteric, lipemic, or turbid specimens.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)

Interpretive Data
Component | Interpretation |
---|---|
Dengue Fever Virus Antibody, IgG | 1.64 IV or less: Negative - No significant level of detectable dengue fever virus IgG antibody. 1.65-2.84 IV: Equivocal - Questionable presence of antibodies. Repeat testing in 10-14 days may be helpful. 2.85 IV or greater: Positive - IgG antibody to dengue fever virus detected, which may indicate a current or past infection. |
Dengue Fever Virus Antibody, IgM | 1.64 IV or less: Negative - No significant level of detectable dengue fever virus IgM antibody. 1.65-2.84 IV: Equivocal - Questionable presence of antibodies. Repeat testing in 10-14 days may be helpful. 2.85 IV or greater: Positive - IgM antibody to dengue fever virus detected, which may indicate a current or recent infection. However, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection. |
