There are three virus test categories in the U.S. Two diagnose whether you have an active infection, and a third indicates if you previously had the virus.
COVID-19 rapid antigen tests or RATs, also frequently called COVID-19 lateral flow tests or LFTs, are rapid antigen tests used to detect SARS-CoV-2 infection . They are quick to implement with minimal training, cost a fraction of other forms of COVID-19 testing , and give users a result within 5–30 minutes.

COVID-19 Antigen Rapid Test Kit; the timer is provided by the user. Mucus from nose or throat in a test liquid is placed onto a COVID-19 rapid antigen diagnostic test device. COVID-19 rapid testing in Rwanda. An antigen is the part of a pathogen that elicits an immune response. Antigen tests look for antigen proteins from the viral surface.
A NASA illustration of a lateral flow assay. A lateral flow test (LFT), [1] is an assay also known as a lateral flow immunochromatographic test (ICT), or rapid test.It is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment.
The WHO did not offer any test kits to the U.S. because the U.S. normally had the supplies to produce their own tests. [3] The United States had a slow start in widespread SARS-CoV-2 testing. [4] [5] From the start of the outbreak until early March 2020, the CDC gave restrictive guidelines on who should be eligible for COVID-19 testing. The ...

To do this, antibodies that are specific to different types of viruses are mixed with the tissue sample. After the tissue is exposed to a specific wavelength of light or a chemical that allows the antibody to be visualized. [citation needed] These tests require specialized antibodies that are produced and purchased from commercial companies.
