Dengue Fever IgG & IgM in Howrah
Understanding Dengue Fever IgG & IgM in Howrah
What is Dengue Fever IgG & IgM in Howrah?
A Dengue Fever IgG & IgM test is performed to check the presence of IgG and IgM antibodies produced by the immune system of an affected individual in response to dengue infection. It helps determine the stage of disease, differentiate between recent and past infections, and aid in the appropriate and timely management of the infection.
What does Dengue Fever IgG & IgM measure?
Contains 2 testsA Dengue Fever IgG & IgM test measures two parameters in the blood: IgG and IgM antibodies. When a dengue infection occurs, IgM antibodies are the first line of defense, and detection of these antibodies is most effective when done at least 7–10 days after exposure. With time, IgM antibodies fall below detectable levels. IgG antibodies, however, are produced more slowly in response to the infection. Levels of IgG rise with acute infection, stabilize, and persist for a long time.
Dengue fever is usually caused by the four dengue virus serotypes, with symptoms ranging from asymptomatic infection, undifferentiated fever, dengue fever (DF) to severe dengue hemorrhagic fever (DHF) with or without shock.
Dengue hemorrhagic fever (DHF) can go to a higher grade of fever. It might also include variable manifestations, like nose bleeding, vomiting blood, passing blood in the stool, breathing difficulty, cold, and clammy skin, especially in the extremities. During the second phase, the virus may attack blood vessels, causing capillaries to leak fluid into the space around the lungs (pleural effusion) or the abdominal cavity (ascites).
Dengue shock syndrome (DSS) is a severe complication of dengue fever caused when the body's immune system overreacts to the dengue virus. It can lead to a sudden drop in blood pressure and dehydration, and if not managed timely, it may lead to multiple organ failures.
Dengue Antibody IgM
A Dengue Antibody IgM test measures the presence of Immunoglobulin M (IgM) antibodies in the blood. It specifically detects the dengue-specific IgM antibodies produced by the body in response to the dengue virus. When a dengue infection occurs, IgM antibodies are the first line of defense. It helps identify recent dengue virus infection as the production of IgM antibodies typically occurs within the first few days to a couple of weeks after the onset of the symptoms.

Dengue Fever IgG Antibody, EIA
A Dengue Fever IgG Antibody, EIA test measures the presence of Immunoglobulin G (IgG) antibodies specific to Dengue virus in the blood. These antibodies typically appear in the blood a few weeks after the onset of dengue symptoms or exposure to the virus. However, this can vary, but generally IgG antibodies become detectable during the recovery phase of the infection.
IgG antibodies indicate a past exposure or infection with the Dengue virus and provide information about the individual’s immune response to the virus.a
