NS1 antigen test (non-structural protein 1), is a test for Dengue. It allows rapid detection on the first day of fever, before antibodies appear. This test detects the presence of the NS1 antigen, a protein produced by the Dengue virus, in a patient's blood. It is effective during the early stages of infection, similar to RT-PCR. The NS1 antigen test is often used as a rapid diagnostic test. These tests provide quick results, allowing healthcare providers to make timely diagnostic and treatment decisions.
