The dengue NS1 antigen-ELISA (Enzyme-linked immunosorbent assay) test helps in the detection of the dengue virus in the blood. This test determines the presence of the dengue NS1 antigen, which is a protein generated by the dengue virus. The dengue NS1 antigen test is performed to detect dengue in its initial stages and to monitor the treatment of the virus.

Overview of the Dengue NS1 Antigen

The NS1 antigen test is performed on a blood sample and is used to detect the presence of the NS1 antigen. The NS1 antigen shows up in the patient’s blood during dengue infection and is detectable during the acute stages of the infection. A positive NS1 antigen test can help detect the presence of the dengue virus in the blood but cannot provide information about the serotype of the virus. During the early clinical phase of the disease, this NS1 antigen is found in high amounts in the blood as it is secreted into the blood almost as soon as the symptoms of dengue develop As a result, the NS1 antigen (ELISA) test for dengue aids in the early detection of the virus.
