Dengue IgG/IgM Ab Rapid Test Uncut Sheet

Intended Use

The One Step Dengue IgA/IgG/IgM Test is a rapid chromatographic immunoassay for the qualitative detection of antibodies (IgA, IgG and IgM) to dengue virus in Whole Blood /Serum / 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 IgA/IgG/IgM Test is a simple, visual qualitative test that detects dengue virus antibodies in human Whole Blood/serum/plasma. The test is based on immunochromatography and can give a result within 15 minutes.  

Principle

The One Step Dengue IgA/IgG/IgM Test is a qualitative membrane strip based immunoassay for the detection of dengue virus antibodies (IgA, IgG and IgM) in Whole Blood /Serum / Plasma. The test device consists of: 1) a burgundy colored conjugate pad containing dengue recombinant envelope antigens conjugated with Colloid gold (dengue conjugates), 2) a nitrocellulose membrane strip containing three test lines (T1, T2and T3 lines) and a control line (C line). The T1 line is pre-coated with the antibody for the detection of IgA anti-dengue, The T2 line is pre-coated with the antibody for the detection of IgM anti-dengue, T3 line is coated with

antibody for the detection of IgG anti-dengue. When an adequate volume of test specimen is dispensed into the sample well of the test cassette, the specimen migrates by capillary action across the cassette. IgG anti-dengue, if present in the specimen, will bind to the dengue conjugates. The immunocomplex is then captured by the reagent pre-coated on the T3 band, forming a burgundy colored T3 line, indicating a dengue IgG positive test result. IgM anti-dengue if present in the specimen will bind to the dengue conjugates. The immunocomplex is then captured by the reagent coated on the T2 line, forming a burgundy colored T2 line, indicating a dengue IgM positive test result. IgA anti-dengue if present in the specimen will bind to the dengue conjugates. The immunocomplex is then captured by the reagent coated on the T1 line, forming a burgundy colored T1 line, indicating a dengue IgA positive test result. Absence of any T lines (T1, T2and T3 lines) suggests a negative result. To serve as a procedural control, a colored line will always appear at the control line region indicating that proper volume of specimen has been added and membrane wicking has occurred.

Storage and Stability

Store as packaged in the sealed pouch at room temperature or refrigerated (4-30℃ or 40-86℉). The test device is stable through the expiration date printed on the sealed pouch.

The test must remain in the sealed pouch until use.
