Dengue is spread by mosquitoes and can be found worldwide in subtropical and tropical climatic conditions. With the help of the NS1 antigen test, the dengue profile test may determine whether the virus is present as well as whether the body has produced any antibodies (IgG and IgM) to combat the illness. In the first few days following the development of fever, from the first day of fever to the fifth day, non-structural protein known as NS1 antigen is identified in infected patients. IgM and IgG antibody tests that are positive indicate that a recent dengue infection might have occurred. IgG levels that are higher than IgM indicate a prior infection in the person.
