IgM-IgG Combined Antibody Rapid Test kit is one of the world’s first rapid screening tests for the identification of corona virus infection. This accurate screening test is similar to the type that was used widely by the Chinese Centre for Disease Control and Prevention to identify COVID-19 infections and is now available from Relax UK Ltd. The single-use finger prick test detects both early and late marker IgG/IgM antibodies in whole blood, serum or plasma.

COVID-19 IgG/IgM Antibody Rapid Test Kit: whole blood,serum/plasma specimen test kit.

Test result shows after 10 minutes!

Blood/Serum/Plasma specimen

1) Take out the test cassette, leave at room temperature for 15-30 minutes.

2) Add 80ol of blood, serum or plasma to the sample well by using the dropper.

3) Observe the results after 15 minutes, results showing after 20 minutes have no significance.


COVID-2019 IgG Postive: One red line appears in the region G and the other line appears in the region C.

COVID-2019 IgM Postive: One red line appears in the region M and the other line appears in the region C.

COVID-2019 IgG & IgM Postive: One red line appears in the region G, One red line appears in the region M, and the other line appears in the region C. The positive results showed that the COVID-2019 antibody was present in the samples.

This kit is used for the qualitative detection of the antibody of the COVID-19 in human blood, serum or plasma. It is mainly used for clinical reference. Tests are intended to be used on patients exhibiting symptoms of COVID-19. They will be expected to show positive 7 days after infection and/or 3 days after the onset of symptoms.

CE quality marked.

Detection Principle

According to the principle of double antibody sandwich method, the kit uses immunochromatographic technology to detect the IgG/IgM antibody of C OVID-19 in human serum/ plasma/whole blood. The C OVID-19 characteristic protein RBD protein antibody in the sample binds to the colloidal gold labeled RBD protein, and the mixture is chromatographed to the kit T1 line and T2 line combining to the mouse anti-human IgG/IgM antibody respectively to form a visible detection line.
