- Description
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.
Collection Note: Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Specimens must be plainly marked as "acute" or "convalescent."

Dengue Fever Virus Antibody, IgG:
Value: Interpretation: 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:
Value: Interpretation: 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. - Guidelines
