The FactView Dengue NS1 Antigen test is a diagnostic assay used for the rapid detection of the non-structural protein 1 (NS1) antigen produced by the dengue virus. Here's more information about this type of diagnostic test:
Purpose: The test is used for the early detection of dengue virus infection. Dengue is a mosquito-borne viral infection caused by four closely related viruses (DENV-1, DENV-2, DENV-3, and DENV-4) transmitted by Aedes mosquitoes.
Principle: The FactView Dengue NS1 Antigen test is an immunochromatographic assay that detects the presence of the NS1 protein in a patient's blood sample. NS1 is a viral protein produced during acute dengue infection and can be detected in the bloodstream during the early stages of the disease.
Components: The test typically includes test cassettes, sample droppers, buffer solutions, and desiccants. The test cassettes contain pre-coated membranes with specific antibodies for capturing the NS1 antigen.
Procedure: The test procedure involves collecting a small amount of blood from the patient (usually obtained via finger prick) and applying it to the sample well of the test cassette. Buffer solution is then added, allowing the blood sample to migrate along the test strip. Results are typically visible within 15-20 minutes.
Interpretation: The appearance of colored lines on the test strip indicates the presence or absence of the NS1 antigen. A visible line in the control region indicates that the test is valid. Additional lines in the test region(s) indicate positive results for NS1 antigen.
Sensitivity and Specificity: The FactView Dengue NS1 Antigen test demonstrates high sensitivity and specificity for detecting dengue virus infection during the early stages of illness. However, like all diagnostic tests, false-positive and false-negative results are possible and should be interpreted in conjunction with clinical findings.
Utility: Rapid diagnostic tests like the FactView Dengue NS1 Antigen test provide a quick and convenient method for diagnosing dengue virus infection in resource-limited settings, where access to laboratory facilities and molecular testing may be limited.
Limitations: While rapid diagnostic tests are valuable tools for dengue diagnosis, they have limitations compared to more sensitive methods such as nucleic acid amplification tests (NAATs) or virus isolation. Factors such as test storage conditions, operator technique, and the stage of infection can influence test performance.
INTENDED USE The One Step Dengue NS1 Ag Test is a rapid chromatographic immunoassay for the qualitative detection of dengue virus NS1 antigen in serum or plasma to aid in the diagnosis of Dengue viral infection. SUMMARY Dengue is transmitted by the bite of an Aedes mosquito infected with any one of the four dengue viruses. It occurs in tropical and sub-tropical areas of the world. Symptoms appear 3 14 days after the infective bite. Dengue fever is a febrile illness that affects infants, young children and adults. Dengue haemorrhagic fever (fever, abdominal pain, vomiting, bleeding) is a potentially lethal complication, affecting mainly children. Early clinical diagnosis and careful clinical management by experienced physicians and nurses increase survival of patients. One step Dengue NS1 Ag Test is a simple, visual qualitative test that detects dengue virus NS1 antigen in human serum or plasma. The test is based on immunochromatography and can give a result within 15 minutes. 25PCS/BOX
