They are less sensitive than a PCR test and are looking for a specific viral antigen that implies there is an infection. Antigen tests can be done in a doctor's office, pharmacy or pop-up testing ...

A strip of eight PCR tubes, each containing a 100 μL reaction mixture Placing a strip of eight PCR tubes into a thermal cycler. The polymerase chain reaction (PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a part of it) sufficiently to enable detailed study.
The thermal cycler (also known as a thermocycler, PCR machine or DNA amplifier) is a laboratory apparatus most commonly used to amplify segments of DNA via the polymerase chain reaction (PCR). [1] Thermal cyclers may also be used in laboratories to facilitate other temperature-sensitive reactions, including restriction enzyme digestion or rapid ...
Polymerase chain reaction (PCR) is a process that amplifies (replicates) a small, well-defined segment of DNA many hundreds of thousands of times, creating enough of it for analysis. Test samples are treated with certain chemicals [ 22 ] [ 23 ] that allow DNA to be extracted.
Point-of-care testing is being developed to speed up the time for testing, and to help practitioners avoid prescribing unnecessary antibiotics in the style of precision medicine. [39] Traditional techniques typically take between 12 and 48 hours, [6] although it can take up to five days. [28]
PCR food testing is the engagement of polymerase chain reaction (PCR) technologies for the testing of food for the presence or absence of human pathogens, such as E. coli, Salmonella, Listeria, [1] etc. [2] Four sample collection sites for PCR food testing can be: The food irrigation water. The food wash water.
The polymerase chain reaction (PCR) is a commonly used molecular biology tool for amplifying DNA, and various techniques for PCR optimization which have been developed by molecular biologists to improve PCR performance and minimize failure.
