Dengue Virus Antibody, IgG and IgM, Serum
Use
Dengue virus (DV) is a globally distributed flavivirus with 4 distinct serotypes. It is primarily transmitted by the Aedes aegypti mosquito, posing a significant public health threat. The presence of IgG antibodies is consistent with past exposure, while IgM antibodies indicate an acute-phase infection. Detection of these antibodies is crucial for diagnosing dengue infections, which can have substantial health implications, particularly in tropical and subtropical regions.
Special Instructions
Not provided.
Limitations
False-positive results may occur, especially with other flavivirus infections like Zika or West Nile virus. Interpretation should consider recent blood product transfusions, immunosuppressive states, and the potential cross-reactivity of IgG antibodies with other flaviviruses.
