DENGUE VIRUS ANTIBODY

Lab Section Category	Virology View write-up
Test Description	Dengue IgM antibody (anti-Dengue IgM) Dengue IgG antibody (anti-Dengue IgG)
Specimen Required	3 – 5 mL plain blood. To diagnose acute infection, send acute sample for dengue IgM antibody and if necessary, a second sample taken 7 – 10 days later for dengue IgM on the pair. To identify previous exposure to dengue virus, please send a sample for dengue IgG. Although seroconversion of dengue IgG on paired samples 7-10 days apart demonstrates acute infection, dengue IgM and dengue NS1 antigen detection are preferred tests for diagnosis.
Storage/Transport	Refrigerate samples if delay in transporting to laboratory is anticipated. Do not freeze.
Method	Dengue IgM/ IgG : Enzyme immunoassay
Test Results	Acute infection: IgM antibody positive on acute serum or paired sera showing seroconversion of IgM and/or IgG Past infection: Presence of IgG antibody in the absence of specific IgM Note: A positive result can be due to cross-reactive flavivirus antibodies and should be correlated clinically.
Turnaround Time	Dengue IgM : <1 – 5 days Dengue IgG : <1 – 7 days
Day(s) Test Set up	Dengue IgM : Monday, Wednesday and Friday Dengue IgG : Thursday
