A Dengue Fever IgG Antibody (ELISA) test detects the presence of IgG antibodies against the dengue virus in the blood. These antibodies typically appear several days after the initial infection and can persist for months or even years. A positive IgG result indicates a past dengue infection, suggesting immunity to the specific dengue serotype. This test is helpful in differentiating between primary and secondary dengue infections, which can have different clinical presentations and potential complications.

A Dengue Fever IgG Antibody, EIA test detects the presence of IgG antibodies against the dengue virus in your blood. These antibodies typically appear later in the course of the infection, usually after about a week, and can persist for several years. A positive IgG result indicates a past dengue infection, suggesting immunity to the specific dengue serotype. This test is often used in conjunction with the IgM antibody test to differentiate between recent and past infections.

Dengue - NS1 Antigen (Qualitative) test is a rapid diagnostic method used to detect the presence of the NS1 protein, a non-structural component of the dengue virus, in a blood sample. This test provides a quick and preliminary result to aid in the early diagnosis of dengue infection. A positive result indicates an active dengue virus infection, while a negative result might require further testing to confirm or rule out the disease. It's important to note that this test is primarily used as a screening tool, and confirmatory testing is often recommended for definitive diagnosis.
