What are COVID-19 Antigen Test Kits and How do they Work?

SARS-CoV-2 is the virus that causes COVID-19 and is present in the human nasopharynx. Rapid antigen testing is designed to detect certain antigens (molecules that bind to a specific T-cell receptor or antibody).

Antigen COVID test kits contain sterile swabs. These swabs are meant to be inserted into an individual’s nostril and rotated three to four times. After withdrawing the swab from the nasal cavity, it is inserted into an extraction buffer tube. It is recommended that users squeeze the tube while stirring the swab in the solution (aim for five times). The swab is then removed, and a nozzle cap is pressed onto the tube. Users add three to four drops of the extracted sample to the COVID test device’s specimen well. After 15 minutes, a colored line should appear in the C section and/or the T section of the result window. Reading results after 30 minutes may lead to inaccuracies.

What are COVID-19 Antibody Test Kits and How do they Work?

Over-the-counter antibody test kits look for COVID antibodies in infected patients. Our body’s immune system produces antibodies (a type of protein) to fight infections. The human body takes approximately one to three weeks to develop antibodies after infection. Therefore, the type and timing of antibody tests affect accuracy. OTC antibody tests, however, are still a good way to determine if a person has significant exposure to COVID-19. It is important to note that COVID antibody tests should not be used to diagnose someone with an active infection; they are performed after the patient makes a full recovery. An antibody test requires a blood sample, which can be acquired by venous blood draw or finger prick.
