What is NS1 in dengue tests?
NS1 in dengue ns1 test is a very important non-structural glycoprotein of dengue virus, which is widely present in dengue virus types 1-4. Therefore, the NS1 protein is the main marker antigen of dengue virus infection.
NS1 protein appears earlier than IqM antibody, and NS1 protein can be detected even when dengue virus RNA cannot be detected. That is, NS1 is positive and IGM is negative. In the early stage of dengue virus infection, NS1 antigen is expressed in large quantities and exists in the blood of infected people.
At present, the detection of NS1 antigen has become the preferred method for early rapid diagnosis of dengue virus infection. This DVOT Dengue Fever NS1 IGM IGG Antigen Antibody Test Reagent is a three-combination test Kit
What is the difference between NS1 and IgM in dengue?
Dengue virus NS1 antigen test reagent is suitable for early auxiliary diagnosis and screening of dengue virus infection。
The dengue virus LGG and IGM antibody combined detection reagent is suitable for the identification and screening of primary and secondary dengue virus infection.

What is dengue?
Dengue fever is an insect-borne viral infectious disease caused by dengue virus (divided into 4 serotypes, DEN-GUE-1~4). The virus is transmitted to humans through Aedes aegypti and Aedes albopictus bites. This mosquito likes to lay eggs and reproduce in shallow water. This virus mainly occurs in Southeast Asian and Latin American countries, such as Malaysia, Thailand, the Philippines, Bangladesh, Pakistan, Brazil, Puerto Rico, Argentina, and Paraguay.
The main symptoms are high fever, muscle and limb joint pain, bleeding, rash, etc. The test results are generally leukopenia, thrombocytopenia, and liver damage. The incubation period of the virus is 3-14 days, and then the clinical symptoms of bleeding appear.
How do you treat dengue NS1 positive?
There is no specific treatment plan at present, only prevention in advance, rapid and accurate diagnosis of suspected DENGUE infected patients, rapid isolation of the source of infection, and timely treatment of patients to minimize the harm of dengue fever. You can buy dengue ns1 igm igg antigen-antibody test kit for test if you have dengue symptoms. The dengue ns1 antigen test price Philippines is 1usd around.
What if NS1 is positive and IgG and IgM is negative?
NS1 is positive, while IgM and IgG are negative, indicating that the infection with dengue is in the early stage. The incubation period of dengue virus is 3-14 days. NS1 is positive, indicating that the surface is infected with dengue virus. IgM and IgG antibodies have not yet appeared, because they will appear later. IGM IGG antibody test can be continued 1-3 days later.
