!This test requires professional lab infrastructure and staff. This test cannot be performed by private individuals and we do not sell the kits to such individuals. If you suspect you are infected with SARS-CoV-2, please contact your healthcare provider.

The RAPIT COVID-19 lgM/lgG Test Kit is intended for the qualitative detection of IgM and IgG antibodies against SARS-CoV-2, for research use.  This test can be used with human plasma, serum, fingerstick whole blood, or whole blood.

In response to infection with SARS-CoV-2, the human body produces anti-SARS-CoV-2 antibodies that function to detect pathogens, promote immunity, and provide protection against the virus. The presence of antibodies to SARS-Cov-2 in blood samples are indicative of immune responses to the viral pathogen.  IgM antibodies can be detected in blood samples within days following SARS-CoV-2 infection and function as a primary response to infection. IgG antibodies have important functions during antigen detection and are abundantly produced in response to SARS-CoV-2 infection.

The RAPIT COVID-19 lgM/lgG Test Kit is a valuable assay for the detection of IgG and/or IgM antibodies against SARS-CoV-2 antigens, which can indicate acute or recent infection.  This test kit provides rapid results within minutes of test administration and is a useful tool during the research of SARS-CoV-2 immune responses and serological population surveys.

 RAPIT COVID-19 lgM/lgG Test Kit Contents Include:

  • Mixed gold-labeled recombinant SARS-CoV-2 antigens
  • Quality control protein labeled conjugates
  • Two test lines, pre-coated with anti-human IgM (M) and anti-human IgG (G) antibodies
  • Control line, pre-coated with an antibody against the quality control protein

When the sample is applied to the test strip, gold-labeled recombinant SARS-CoV-2 antigens bind anti-SARS-CoV-2 IgM and/or IgG antibodies found in the sample, forming antibody-antigen complexes.  The antibody-antigen complexes are then immobilized by the anti-human IgM and IgG antibodies located on the test lines. The immobilized antibody-antigen complexes are detected by the sample diluent that flows downward, giving a purplish red color. The control line is an internal control and should always appear when the test procedure is performed properly. Absence of a control line indicates either an error with the assay technique or a faulty device.

 

Interpretation of Data:

Positive for COVID-19 antibodies:  A test is positive if the control line (C) visually appears along with any visible test lines (M/G)

Negative for COVID-19 antibodies: A test is negative when the control line (C) visually appears with no other visible test lines.

Invalid Result: A test is invalid if the control line (C) is absent. The assay should be repeated using a new device.
