Dengue IgM/IgG rapid test cassette ( Assay+ )
Dengue NS1 rapid test ( Assay+ )
1. Early detection of Dengue IgM and Dengue IgG in serum or plasma for in vitro diagnostic use
Assay principle :
The recombinant dengue antigens are used in the test, the dengue antigens used for this test cover all four dengue serotypes. Serum or plasma from dengue infection is loaded to the device, the specific dengue antibodies in specimen will bind to gold-conjugated dengue antigens forming antibody colloid gold-antigen complex. While the complex migrates along nitrocellulose membrane, the complex is captured by the test lines coated with anti-human IgG or IgM forming a pink to deep pink band at the IgG or IgM test line. The signal intensity is variable depending on the amount of specific antibody present in specimen. A red control line should always develop over control line indicating the proper performance.
This test device can detect all four dengue serotype infection. The sensitivity to detect dengue IgG and IgM is over 85% to 90%.
2. Dengue NS1 rapid test cassette formAssay+
Intended use: whole blood, serum, plasma
Assay principle:
80 to 120 microliter serum or plasma sample is used for the test. After specimen is loaded to the test device, dengue NS1 antigen in the specimen sample is captured by gold-conjugated monoclonal anti-dengue NS1 antibody, forming the complex with the components of dengue NS1 antibodyconjugated gold and dengue NS1 antigen, migrating along nitrocellulose membrane, the complex is captured by another dengue NS1 antibody coated on the test line to form a pink to deep pink band. The intensity of the band is variable depending on the amount of dengue NS1 antigen present in the blood sample. A red control line should always develop on the test strip indicating the proper performance.
This test device can detect all four dengue serotype virus infection and applied for the early diagnosis of dengue infection. Assayplus dengue NS1 has the sensitivity over 80% and specifity is over 95%.
