Detecting Principles
The COVID-19 IgG/IgM test kit (Whole Blood/Serum/Plasma) is a lateral flow
immunochromatographic assay. The burgundy coloured conjugate pad contains recombinant COVID-19 antigens conjugated with colloidal gold (COVID-19 conjugates) and rabbit IgG-gold conjugates.
When a specimen – followed by sample diluent – is added to the sample well, IgM and/or IgG antibodies – if present – will bind to COVID-19 conjugates to form an antigen antibody complex.
This complex migrates through the nitrocellulose membrane by capillary action.
When the complex meets the line of the corresponding immobilized antibody (anti-human IgM and/or anti-human IgG), it is trapped to form a burgundy coloured band, which indicates a positive test result.
The absence of a coloured band in the test region indicates a negative test result. The test contains an internal control (C band) which should give a burgundy coloured band for the immunocomplex goat anti-rabbit IgG/rabbit IgG-gold conjugate, regardless of the colour development on any of the test bands. Otherwise, the test result is invalid and the specimen must be retested with another device.
