Dengue is a mosquito-borne viral infection caused by the dengue virus. The body produces IgM antibodies in the early phase (after a few days of infection) and IgG antibodies later or during secondary infections. The rapid card test helps detect these antibodies quickly, aiding doctors in confirming dengue infection and understanding whether it is recent, ongoing, or past exposure.
Uses of the Test
Diagnose dengue infection in later stages (after 4–5 days of fever)
Differentiate between primary (IgM) and secondary (IgG) infection
Evaluate symptoms like fever, body pain, rash, weakness, and low platelet count
Support diagnosis when NS1 antigen test is negative
Help in monitoring disease progression
