Dengue Fever Virus Antibodies, IgG and IgM
Also known as: DENGUE AB
Use
This test may aid in the diagnosis of dengue fever when the timing of the infection is uncertain. It assesses the presence of IgG and IgM antibodies to the dengue fever virus, which are indicative of a current or past infection. Testing is also recommended for differentiation from other arthropod-borne viruses with similar symptoms, often influenced by clinical presentation and travel history.
Special Instructions
Parallel testing is preferred, and convalescent specimens should be received within 30 days from receipt of acute specimens. Specimens must be marked clearly as 'acute or convalescent.'
Limitations
IgG antibodies may not be detectable in the early stages of infection, as the IgG response can take several weeks to develop. In such cases, IgM testing is recommended. Low levels of IgM may occasionally persist for more than 12 months post-infection, possibly leading to false results. This test is not FDA cleared or approved.
