The US CDC's COVID-19 laboratory test kit. COVID-19 testing involves analyzing samples to assess the current or past presence of SARS-CoV-2, the virus that cases COVID-19 and is responsible for the COVID-19 pandemic. The two main types of tests detect either the presence of the virus or antibodies produced in response to infection.

The annealing temperature during a polymerase chain reaction determines the specificity of primer annealing. The melting point of the primer sets the upper limit on annealing temperature. At temperatures just above this point, only very specific base pairing between the primer and the template will occur.

The reliance upon Taq polymerase as a catalyst for the PCR replication process has been highlighted during the COVID-19 Pandemic of 2020. Shortages of the necessary enzyme have impaired the ability of countries worldwide to produce test kits for the virus. Without Taq polymerase, the disease detection process is much slower and tedious. [25]
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 ...
The RT-LAMP technique is being supported as a cheaper and easier alternative to RT-PCR for the early diagnostics of people that are infectious for COVID-19. [6] There are open access test designs (including the recombinant proteins) which makes it legally possible for anyone to produce a test.
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.
