Dengue Rapid Tests

 

Los Angeles-based Diagnostic Automation/Cortez Diagnostics, Inc., a leading manufacturer and distributor of Dengue Fever Rapid Tests, offers an easy-to-use Dengue Rapid Test to identify the dengue virus.  This Dengue Fever Rapid Test is a qualitative test for the detection of IgM and IgG antibodies to dengue virus in human serum, plasma or whole blood. The Dengue rapid test provides a differential detection of anti-dengue IgM and anti-dengue-IgG antibodies.  The Dengue Rapid Test can be used for the presumptive distinction between a primary and secondary dengue infection.   A high proportion of dengue virus infections can be detected swiftly and easily using a Dengue Rapid Test.  The Dengue Rapid Test can help to diagnose active dengue infections from the very first day fever appears.  In facilitating early diagnosis by using this Dengue Rapid Test, therapy and monitoring can begin much earlier, reducing the risk of severe complications.  Early and prompt diagnosis with the Dengue Rapid Test can facilitate vector control activities in the community so as to mitigate further transmission.  Also, the expanded use of accurate Dengue Rapid Tests provides important data on the epidemiology and health burden of dengue and in doing so can inform and guide public health policy.

 

According to the World Health Organization’s 2009 Report, “Dengue is the most rapidly spreading mosquito-borne viral disease in the world.  In the last 50 years, incidence has increased 30-fold with increasing geographic expansion to new countries. . . . An estimated 50 million dengue infections occur annually and approximately 2.5 billion people live in dengue endemic countries.”  Because of the vast implications of these findings, it is essential that early detection of dengue fever, like those offered using Dengue Rapid Tests, is vitally important for the prompt care and treatment of infected individuals. Timely, sensitive, and easy to use, the Dengue Rapid Tests are essential for early detection and identification of the infection so that treatment may be started without delay.

 

DENGUE RAPID TEST – NOTABLE FEATURES

 

The Dengue Rapid Test, or OneStep Dengue RapiCardTM InstaTest, is a immunochromatographic assay for the simultaneous detection of IgG and IgM antibodies to Dengue virus in human whole blood, serum or plasma. The assay is used as a screening test for Dengue viral infection and as an aid for differential diagnosis of primary and secondary infections in conjunction with other criteria.  This Dengue Rapid Test is a new generation immunochromatographic test using recombinant dengue viral antigens of all four serotypes to detect specific antibody response. This convenient and easy-to-use Dengue Rapid Test is for in-vitro diagnostic use only.  The Dengue Fever Rapid Test provides an excellent methodology for specifically detecting anti-dengue IgG and IgM antibodies. The presence of high titers of IgG antibodies on the Dengue rapid test does not interfere with the detection of IgM antibodies in the sample.  By using a mixture of highly purified dengue proteins, the Dengue rapid test is able to detect all 4 Dengue serotypes.

Serum, plasma or whole blood samples may be used with this Dengue rapid test. When a specimen is added to the Dengue rapid test, IgG and IgM antibodies in the specimen sample react with blue particles coated with dengue envelope proteins. As this specimen/particle mixture migrates along the length of the Dengue rapid test, the anti-dengue IgG or IgM antibody particle complex is captured by the relevant IgG and/or IgM test bands located in the Dengue rapid test device window causing a pale to dark blue band to form at the IgG or IgM region of the test device window. The intensity of the bands on the Dengue rapid test will vary depending upon the amount of antibody present in the sample. The appearance of any color in a specific Dengue rapid test region (IgG or IgM) should be considered as positive for that particular antibody type (IgG or IgM).  A red procedural control line should always develop in the Dengue rapid test device window to indicate that the Dengue rapid test has been performed properly.

Timely, sensitive, and specific diagnosis of dengue virus is important for early detection of dengue virus infection.  However, some available tools for dengue diagnosis are time-consuming.  The use of tests like the Dengue NS1 Rapid Test as a first-line test for the screening of dengue infected patients, using serum samples collected during the onset of clinical symptoms, could help to accelerate the diagnosis of dengue fever in clinical diagnostic laboratories.    Rapid and easy diagnosis of dengue using Dengue NS1 Rapid Test can assist patient triage and care management.  For example, during an epidemic outbreak, the ability to triage those patients suspected of dengue fever and to quickly establish an anti-viral therapy with use of the Dengue NS1 Rapid Test, might improve the rates of disease control drastically.  Recent studies have shown that sensitivity and specificity tests, like the Dengue NS1 rapid test, were highly specific to DENV NS1, and the Dengue NS1 rapid test produced enhanced diagnoses at high detection rates.  Thus, the Dengue NS1 Rapid Test presents the ideal method of testing as it is rapid, easily applicable, sensitive, and highly specific.

 

DENGUE NS1 RAPID TEST – FAST RESULTS

Dengue virus, a virus belonging to the Flavavirus group of viruses, is one of the most significant mosquito-borne diseases in the world in terms of morbidity and mortality. Transmitted principally by the mosquito types Aedes aegypti and Aedes albopictus, the virus is found commonly throughout the tropic and subtropic regions of the world. Symptoms of dengue fever include high fever, headache, muscle pain and skin rash. The complications often associated with this infection are dengue hemorrhagic fever or dengue shock syndrome.

 

The detection of DENV NS1 using the Dengue NS1 Rapid Test offers a fast route to a dengue diagnosis.  Physicians using this Dengue NS1 Rapid Test in early convalescence diagnostic strategy on patients should be able to obtain rapid and specific dengue diagnosis within a few minutes.  The positive correlation between viral load, disease progression and detection of NS1, suggests that tests like the Dengue NS1 Rapid Test might be a valuable test to include in dengue triage protocols in areas of high incidence of dengue infection.

 

The Dengue NS1 Rapid Test is a qualitative, membrane based immunoassay for the detection of NS1 antigen in human serum.  The Dengue NS1 Rapid Test membrane is pre-coated with NS1 specific antibody on the Dengue NS1 Rapid test line region and utilizes a separate control to assure assay flow and performance.  If NS1 antigen is present on the Dengue NS1 Rapid Test, a red line will appear at the test line.  The red line at the control region should always appear if the Dengue NS1 Rapid Test is performed correctly.  The presence of this red line on the Dengue NS1 Rapid Test verifies that proper flow has occurred and catastrophic failure of the conjugate has not occurred.  The Dengue NS1 Rapid Test is positive for the NS1 antigen when the control line (C) and the test line (T) appear in the Dengue NS1 Rapid Test area. A faint line on the Dengue NS1 Rapid Test is considered a positive result. The Dengue NS1 Rapid Test is negative when just the control line appears.
