It’s all about IgG & IgM

Covid-Rapid works by looking for antibodies to the virus in your blood. So there is no uncomfortable swab deep in the nose or throat (PCR test), and more importantly, you know for sure that the sample collected is properly done, which isn’t always true with the swabs. After placing the blood on the strip with the reagent, your blood is carried by capillary action down the strip to where there are pieces of the virus embedded in the paper. If you have the antibodies in your blood, they will react with the pieces of virus and change the color of the paper. Similar to a home pregnancy test, a control line assures that the process has worked correctly. A second and/or third line indicates the presence of one or both of the two types of antibodies produced by your body, called IgM and IgG
