Reference Interval:
 
Test Number Components Reference Interval
0093097Dengue Fever Virus Antibody, IgG 0.89 IV or less: Negative - No significant level of detectable dengue fever virus IgG antibody.
0.90-1.10 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
1.11 IV or greater: Positive - IgG antibody to dengue fever virus detected, which may indicate a current or past infection.
0093098Dengue Fever Virus Antibody, IgM 0.89 IV or less: Negative - No significant level of detectable dengue fever virus IgM antibody.
0.90-1.10 IV: Equivocal - Repeat testing in 10-14 days may be helpful.
1.11 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.
