The outer primers(F3 and B3) anneal to the template strand and help the reaction to proceed. As in the case of RT-PCR , the RT-LAMP procedure starts by making DNA from the sample RNA. This conversion is made by a reverse transcriptase , an enzyme derived from retroviruses capable of making such a conversion. [ 15 ]
Once a one-step RT-PCR kit with a mix of reverse transcriptase, Taq DNA polymerase, and a proofreading polymerase is selected and all necessary materials and equipment are obtained a reaction mix is to be prepared. The reaction mix includes dNTPs, primers, template RNA, necessary enzymes, and a buffer solution.
Loop-mediated isothermal amplification (LAMP) primers [1] Loop-mediated isothermal amplification (LAMP) product [1]. In LAMP, the target sequence is amplified at a constant temperature of 60–65 °C (140–149 °F) using either two or three sets of primers and a polymerase like Bst Klenow fragment with high strand displacement activity in addition to a replication activity.

The German nucleic acid testing protocol was published on the 17th. Another early PCR test was developed by Charité University hospital in Berlin, working with academic collaborators in Europe and Hong Kong, and published on the 23rd. It used rtRT-PCR, and formed the basis of 250,000 kits distributed by the World Health Organization (WHO). [20]
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.

In the first PCR, one pair of primers is used to generate DNA products, which may contain products amplified from non-target areas. The products from the first PCR are then used as template in a second PCR, using one ('hemi-nesting') or two different primers whose binding sites are located (nested) within the first set, thus increasing specificity.
