Understanding Dengue Fever Antigen NS1, IgG & IgM in Lucknow
What is Dengue Fever Antigen NS1, IgG & IgM in Lucknow?
A Dengue Fever Antigen NS1, IgG & IgM test offers a range of blood tests that help detect dengue virus antigen (NS1) and antibodies (IgG and IgM) to diagnose dengue fever. Together, they help determine the stage of dengue infection, differentiate between recent and past dengue infections, and aid in the timely management of the dengue infection. This test is widely available with Tata 1mg Labs at an affordable price in Lucknow.
The presence of NS1 antigen in the blood indicates an acute phase of infection (within the first few days of symptoms). IgM are the first antibodies produced by the immune system (appear within 3-5 days after the onset of symptoms) and their presence suggests a recent dengue infection. Whereas, IgG antibodies develop later in the course of the infection and persist for an extended period. Their presence indicates a past dengue infection or immunity from a previous infection.
Doctors may suggest this test when individuals present with symptoms such as sudden onset of high fever, severe headache, joint and muscle pain, rash, and other flu-like symptoms suggestive of dengue fever. No special preparation is required for this test.
What does Dengue Fever Antigen NS1, IgG & IgM measure?
Contains 3 testsA Dengue Fever Antigen NS1, IgG & IgM test detects the NS1 protein of the dengue virus and the antibodies IgG and IgM produced by the body in response to the infection.
The dengue NS1, also known as dengue nonstructural protein 1, is used to diagnose dengue fever early. This protein is secreted into the blood immediately after the infection; hence, it can be detected during the early stages of the infection.
IgM antibodies are the first type produced by the immune system in response to a dengue infection. The IgM test helps identify recent or primary dengue infections, providing information about the active immune response. It is most accurate when performed a few days after the onset of symptoms. With time, IgM antibodies fall below detectable levels.
IgG antibodies are produced more slowly in response to an infection. Levels of IgG rise with acute infection, stabilize, and persist for a more extended period. The IgG test helps identify past dengue infections and can help assess immunity. It may also be seen in the later stages of an acute infection.
Dengue Fever NS1 Antigen
The Dengue Fever NS1 Antigen test measures the NS-1 protein of the dengue virus. This protein is secreted into the blood during the infection; hence, it can only be detected during the early stages of the illness. It is recommended to do the Dengue Fever NS1 Antigen test in the first 5 days of fever. After 7-10 days of continuous fever, the recommended test is Dengue fever antibodies IgG & IgM.
Dengue fever may progress to dengue hemorrhagic fever or dengue shock syndrome if left untreated. Dengue hemorrhagic fever (DHF) includes variable manifestations like bleeding, vomiting blood, passing blood in the stool, difficulty breathing, and cold, clammy skin, especially in the extremities. If progressed, 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; if not managed timely, it may lead to multiple organ failures.
There is no specific treatment for dengue, but early diagnostic testing, such as the Dengue Fever NS1 Antigen test, can prevent the advancement of dengue to its complicated forms.

Dengue Fever, IgG & IgM
A 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.
