What is a COVID-19 IgG-IgM Rapid Test?
Our test is a lateral flow immunochromatographic assay which tests human blood/serum/plasma for the detection of COVID-19 antibodies.
How does a COVID-19 IgG/IgM Rapid Test work?
Human blood/serum/plasma and buffer solution are inserted into the test cassette, and as they mix and travel over the test strip which is strategically embedded with immobilized antibody, burgundy colored band(s) appear to confirm a reactive test result. Absence of a colored band in the test region indicates a non-reactive test result.
How long does it take for the results?
The result should be read at 10 minutes.
Do not interpret the result after 15 minutes.
What results does the test give?
A total of three detection lines are possible, with the control (C) line appearing when sample has been flowed through the cassette.
If only C band is present, the absence of any burgundy color in both T bands (IgG and IgM) indicates that no anti-COVID-19 antibodies are detected in the specimen. The result is negative.
In addition to the presence of C band, if only IgM band is developed, the test indicates for the presence of COVID-19 IgM antibodies in the specimen. The result is COVID-19 IgM positive.
In addition to the presence of C band, if only IgG band is developed, the test indicates for the presence of COVID-19 IgG antibodies in the specimen. The result is COVID-19 IgG positive.
IgG and IgM POSITIVE
In addition to the presence of C band, if both IgG and IgM bands are developed, the test indicates the presence of both COVID-19 IgG and COVID-19 IgM antibodies in the specimen. The result is COVID-19 IgG and COVID-19 IgM positive.
What are IgG and IgM?
Immunoglobulins are antibodies and are part of our immune system. When we get an infection, such as COVID-19, immunoglobulins are produced, which attach to the virus and activate the rest of the immune system to attack and clear the virus. IgM is the first immunoglobulin to be produced. The presence of IgM is an indicator of early infection. The presence of IgG is an indicator of later stage infection (usually 7 days or longer after infection).
