Interpretive Data

This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.


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.
