A Dengue test is used to detect the presence of the dengue virus or the antibodies produced in response to it. Depending on the stage of infection, doctors may recommend tests like NS1 Antigen, IgM, or IgG. The NS1 test is usually positive in the early days of fever, while IgM and IgG help confirm recent or past infections. Doctors advise this test when symptoms such as high fever, severe headache, joint pain, muscle pain, rash, or weakness suggest a possible dengue infection.

For the Dengue test, a small blood sample is collected from a vein, and no fasting or special preparation is required. These tests help diagnose dengue early, monitor its progress, and guide appropriate treatment. Early detection is important to prevent complications such as dehydration, platelet drop, or dengue hemorrhagic fever.
