#NET SENSITIVITY FOR SEQUENTIAL TESTING PORTABLE#

LamPORE tests combine LAMP with rapid, portable DNA sequencing to detect COVID-19 genetic material. LAMP tests are similar to PCR tests, but they use another method to amplify the genetic material in your sample called real-time loop-mediated amplification (LAMP), which is faster and cheaper than PCR and does not require a laboratory. The LAMP and LamPORE tests look for COVD-19 genetic material in your saliva. LAMP and LamPORE testing What is LAMP testing? It’s also best to confirm any positive lateral flow test result with a PCR test. If you have symptoms that could be COVID-19, you should get a PCR test and not rely on the results of a lateral flow test. Lateral flow tests are around 58 to 79% accurate, which is why they’re only used for mass testing people without symptoms to get a general indication of infections in a population. Lateral flow tests are much less accurate than the PCR tests, particularly when done by members of the public without medical training. Lateral flow tests are available at workplaces, schools, and rapid test centres around the country, and recently became available from selected pharmacies in England as part of a government scheme to increase self-testing. You should get a result in about 30 minutes. If the test is positive you will see two lines and negative just one line, a bit like a pregnancy test. The solution creates a reaction in the testing device. Then you put a few drops of the liquid onto a testing device. When you take a lateral flow test, you swab the inside of your nose and mouth, but instead of sending your swab off to a laboratory, you put the end of the swab in a small pot of liquid. The tests look for specific molecules (antigens) found on the surface of the virus that causes COVID-19. Lateral flow or rapid antigen testing What is a lateral flow test?Īlso known as rapid antigen testing, lateral flow tests are quick tests that you can do yourself. PCR tests detect around 97-99% of positive cases when taken within the first week of symptoms appearing. If you have any of the other 20 or more symptoms associated with COVID-19 and log them in the ZOE COVID Study app, we’ll invite you to book a PCR test. If you have one of the three classic COVID symptoms ( fever, cough, or loss of smell) you can book a PCR test on the government website. Then they add probes that bind to the SARS-CoV-2 genetic code, showing any coronavirus in your sample. Once it arrives, the scientists use a technique called the polymerase chain reaction (PCR) to amplify all the genetic material in your sample. How does PCR testing work?Ī swab is used to rub the inside of your mouth and nose, which is then put in a tube and sent to a laboratory for testing. PCR tests identify the presence of the SARS-CoV-2 virus, which causes COVID-19, in your body. There are now several different types of COVID-19 tests available in the UK: Swab PCR testing, Lateral flow testing, and LAMP/LamPORE testing.We explain the differences in how they work, where you can get them and how accurate they are.
