What are the dengue antigens NS1, IgG

The Easysweet Dengue IgG/IgM And NS1 Combo Rapid Test detects the non-structural protein component (NS1) of the dengue virus and the antibodies (IgG and IgM) produced by the body in response to the infection. NS1 and IgM are secreted into the blood during dengue infection and become detectable within 3-4 days of onset. Therefore, this test helps in early diagnosis and treatment of dengue infection. IgG antibodies appear after day 14 of infection and persist throughout life.


Common initial symptoms of dengue fever include sudden high fever, fatigue and flu-like symptoms.

If left untreated, the infection may develop into serious forms such as dengue hemorrhagic fever or dengue shock syndrome.





Why do Easysweet Dengue IgG/IgM And NS1 Combo Rapid Test?

Dengue antigen NS1, IgG and IgM tests are performed in the presence of high fever within 2 weeks of travel to dengue outbreaks or dengue endemic areas.




What does the Easysweet Dengue IgG/IgM And NS1 Combo Rapid Test measure?



The Dengue Antigen NS1, IgG and IgM test measures dengue virus or antibodies produced in response to dengue infection. Dengue fever is a viral infection transmitted to humans by mosquitoes that live in tropical and subtropical climates and are responsible for carrying the virus.


According to the CDC (Centers for Disease Control and Prevention), dengue infections have been reported in more than 100 countries, parts of Africa, the Americas, the Eastern Mediterranean, the Caribbean Western Pacific, and Southeast Asia.


According to the World Health Organization (WHO), dengue fever is a rapidly emerging infectious disease. The number of cases and the number of countries affected by dengue is increasing significantly. Since 75 percent of cases are asymptomatic, the actual number is unknown, but approximately 390 million dengue infections occur each year.


Most affected people develop no symptoms or only mild illness when exposed to one of the four serotypes of dengue virus. If a patient becomes symptomatic, the prognosis is good, with a full recovery within a few weeks.


Common initial symptoms include sudden onset of high fever and flu-like symptoms about 4 to 7 days after infection with the dengue mosquito. Other signs and symptoms include severe headache, especially behind the eyes, joint and muscle pain, nausea, vomiting, rash, and swollen glands.


In some cases, people recover from the fever on their own, but some may develop severe dengue fever, known as dengue hemorrhagic fever. In this case, symptoms include epistaxis, vomiting blood, blood in the stool, difficulty breathing, and clammy skin, especially on the extremities. In the next stage, stage 2, the virus attacks the vasculature (blood vessels), causing the capillaries to leak fluid into the space around the lungs, which is called pleural effusion, or into the abdominal cavity, called ascites. If left untreated, it can worsen and have fatal health effects.
