Rapid Immunochrometic Test for Detection IgG/IgM of 2019-nCoV


The DABLOOD COVID-19 IgM/IgG Rapid Antibody Test is a rapid test for the qualitative detection of IgM and IgG antibodies associated with the CoV-SARS-2 virus.

DABLOOD is a single-use, self-contained test that provides results in 15 minutes, helping authorities, employers and healthcare workers make informed decisions to contain the spread of COVID-19.

DABLOOD is intended for individuals suspected of COVID-19 infection by a healthcare provider or who were exposed to an individual infected with COVID-19. DABLOOD is also for use by laboratories and healthcare workers at the point-of-care.

DABLOOD detects the presence of antibodies IgM and IgG, developed in response to the SARS-CoV-2 virus.

  • IgM antibodies: develop EARLY after SARS-CoV-2 virus exposure. 
  • IgG antibodies: develop LATER after SARS-CoV-2 virus exposure; indicates longer term immunity.
DABLOOD is a lateral flow immunoassay used to qualitatively detect IgM and IgG antibodies of the SARS-CoV-2 virus in human serum, plasma, or whole blood. The test uses monoclonal mouse anti-human IgM and a monoclonal mouse anti-human IgG conjugated to colloidal gold, each embedded into the sample pad. These respectively react with the IgM and/or IgG SARS-CoV-2 antibodies, if present in human serum, plasma, or whole blood specimens, forming conjugate/SARS-CoV-2 antibody complex. The test control is goat anti-mouse IgG, also embedded into the sample pad.

As the mixture is allowed to migrate along the test strip, the conjugate/SARS-CoV-2 antibody complex is captured by recombinant SARS-CoV-2 antigen immobilized on a membrane forming a colored test line in each test region. There are three (3) test regions that include 1) test control, 2) IgM test region, and 3) IgG test region. The test control line is a specific indicator that the test is functioning correctly and will appear on all test strips. The IgM test line and/or IgG test line will appear when there is the presence of antibodies in the blood sample. The cassette is dual-targeted, with IgM and IgG detected in the same cassette but physically separated, testing each antibody independently.
