SUMMARY

 

  Dengue is a flavivirus, transmitted by Aedes aegypti and Aedes albopictus mosquitoes. It is widely distributed throughout the tropical and subtropical areas of the world,mostly in urban and semi-urban areas.Dengue causes up to 100 million infections annually.Today,about 2.5billion people live in areas where there is a risk of dengue transmission.Clinic feature of Dengue infection are sudden onset of fever, intense headache, myalgia, arthralgia and rash.It is the most severe arbovirus disease that causes human morbidity and death. Primary Dengue infection causes IgM antibodies to increase to a detectable level in 3 to 5 days after the onset of fever. IgM antibodies generally persist for 30 to 90 days.Most Dengue patients in endemic regions have secondary infections, resulting in high levels of specific IgG antibodies prior to or simultaneous with IgM response. Therefore, the detection of specific anti-Dengue IgM and IgG antibodies can also help to distinguish between primary and secondary infections.Early detection and access to proper medical care can lower fatality below 1%. 

  The Dengue Rapid Test Cassette (Whole Blood/Serum/Plasma) is a rapid test that utilizes a combination of Dengue antigen coated colored particles for the detection of IgG and IgM Dengue antibodies in human whole blood, serum, or plasma.It has been evaluated with specimens obtained from a population of symptomatic and asymptomatic individuals. Results were confirmed by a leading commercial Dengue ELISA test.The results show that the overall relative sensitivity for the primary and secondary infection of the Dengue Rapid Test Cassette (Whole Blood/Serum/Plasma) is 95.7%, and the relative specificity is >99.9%,and the relative accuracy is 99.3%.

PRINCIPLE

  The Dengue Rapid Test Cassette(Whole Blood/Serum/Plasma) is a qualitative membrane-based immunoassay for the detection of Dengue antibodies in whole blood, serum, or plasma. This test consists of two components, an IgG component and an IgM component. In the IgG component, anti-human IgG is coated in IgG test line region. During testing, the specimen reacts with Dengue antigen-coated particles in the test cassette. The mixture then migrates upward on the membrane chromatographically by capillary action and reacts with the anti-human IgG in IgG test line region. If the specimen contains IgG antibodies to Dengue, a colored line will appear in IgG test line region. In the IgM component, anti-human IgM is coated in IgM test line region. During testing, the specimen reacts with anti-human IgM. Dengue IgM antibodies, if present in the specimen, reacts with the anti-human IgM and the Dengue antigen-coated particles in the test cassette, and this complex is captured by the anti-human IgM, forming a colored line in IgM test line region.Therefore, if the specimen contains Dengue IgG antibodies, a colored line will appear in the IgG test line region. If the specimen contains Dengue IgM antibodies, a colored line will appear in IgM test line region. If the specimen does not contain Dengue antibodies, no colored line will appear in either of the test line regions, indicating a negative result. To serve as a procedural control, a colored line will always change from Blue to Red in the control line region, indicating that the proper volume of specimen has been added and membrane wicking has occurred.
