Rapid Test

The KBio Sciences COVID-19 IgM/IgG Rapid Test is a lateral flow immunochromatographic assay intended for the qualitative detection and differentiation of anti-SARS-CoV-2 IgM and IgG antibodies in human serum and plasma or whole blood.

The Rapid Test utilizes anti-human IgM, anti-human IgG and anti-chicken IgY as antibodies on membrane strip and SARS-CoV-2 Spike S1 antigen and chicken IgY gold conjugates on conjugate pad.

During testing, if there are IgM and/or IgG antibodies present in the sample introduced (which implies a recent or prior infection), they will form COVID-19 antigen antibodies complex.

As these complexes interact with capture antibodies at Test Line (M and G), a band is formed confirming a positive test result or an absence of a band in the test region indicates a negative test result. The chicken IgY complexes are captured by the control line (C) and a visible band indicates a successful lateral flow across the membrane strip.
