Anti-dengue virus IgG antibody

Dengue virus and forest encephalitis virus (forestencepha-litisVirus) are pathogens causing dengue fever and forest encephalitis, respectively. Dengue fever is widespread in Guangdong, Guangxi, and Hainan, while forest encephalitis occurs in forest areas in the northeast and northwest. These two viruses belong to the same yellow virus as Japanese encephalitis virus, and their morphological structures are similar. Their experimental diagnosis is similar to that of Japanese encephalitis virus. The IgM antibody of dengue virus can be detected by a capture ELISA, and the IgG antibody in the serum of the patient can also be detected by indirect ELISA; as with the JE virus, the hemagglutination inhibitory antibody of the dengue virus can also be detected by a hemagglutination inhibition test. Forest encephalitis virus can be used to detect IgM antibodies by indirect immunofluorescence, and IgG antibodies can also be detected by indirect ELISA. Hemagglutination inhibition antibodies can be detected by hemagglutination inhibition test.

Basic Information

Applicable gender: whether men and women apply fasting: not fasting

Analysis results:

Below normal:

Normal value:

Above normal:


Positive dengue fever.

Tips: Use hemagglutination inhibition test to detect hemagglutination inhibitory antibodies against dengue virus. Normal value
