Reference Interval:

Test Number	Components	Reference Interval
0093097	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.
0093098	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.
