Definition: The Dengue IgG + IgM Antibody + NS1 Antigen Rapid test simultaneously detects dengue-specific IgG and IgM antibodies as well as the NS1 antigen in a single test. This comprehensive approach aids in diagnosing current and recent dengue infections.
Purpose: This test is used for the rapid diagnosis of dengue fever, particularly in patients presenting with clinical symptoms such as high fever, severe headache, and body aches. It helps to determine the stage of infection and the immune response.
Clinical Relevance: By measuring both antibodies and the NS1 antigen, this test allows for early detection of acute dengue infections (through NS1) and later confirmation of past infections (through IgM and IgG). This is particularly valuable in areas where dengue is endemic.
Interpretation: A positive NS1 antigen indicates an active dengue infection, while positive IgM suggests recent infection and IgG indicates past infection. The combination of these results provides a clearer picture of the patient’s dengue status and aids in clinical decision-making.
Testing Method: The rapid test requires a fingerstick or venous blood sample that is applied to a test device. Results are typically available within 15-30 minutes, facilitating prompt diagnosis and enabling timely treatment interventions for patients with suspected dengue fever.
