The novel coronaviruses belong to the β genus. COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Currently, the patients infected by the novel coronavirus are the main source of infection; asymptomatic infected people can also be an infectious source. Based on the current epidemiological investigation, the incubation period is 1 to 14 days, mostly 3 to 7 days. The main manifestations include fever, fatigue and dry cough. Nasal congestion, runny nose, sore throat, myalgia and diarrhea are found in a few cases.

Green Spring® COVID-19 Antigen Saliva Rapid Test Kit (Colloidal Gold) uses COVID-19 antibodies labelled with gold particles that attach to the membrane of the test card near the specimen application position. Once applied, the specimen migrates from the application position to the reading field of the test card due to capillary forces. When the liquid reaches the COVID-19 antibodies, they detach from the membrane and are transported along the test card. There is a test line and a control line in the reading field of the test card.

If the specimen contains SARS-CoV-2 antigens ("analyte"), these bind to the gold-labelled antibodies and create so-called antigen-antibody-gold conjugate complexes. When these complexes reach the test line of the test card, they are retained there by another set of COVID-19 antibodies immobilized on the membrane.

These double complexes appear as a colored stripe on the test line. If the specimen does not contain SARS-CoV-2 antigens, no double complexes are formed and no colored stripe appears on the test line.

Whether or not the specimen contains SARS-CoV-2 antigens, a colored stripe appears on the control line of the test card. If no colored stripe appears on the control line, the Test Card has not functioned properly.
