What is a covid-19 antigen test?

What is a Covid antigen test? COVID-19 antigen tests detect the coronavirus protein in the mouth and throat. This test determines if the patient currently has COVID-19 or not. The antigen test is a rapid test against COVID-19, but it is simpler and faster than other methods such as PCR, especially those that are EU approved. It usually takes about 15 minutes to get results. However, it is less accurate than PCR because it requires a higher antigen content to detect SARS-CoV-2 (COVID-19). The results may be false in early or late illness, but this usually does not happen. How does sampling work? A Corona Antigen Test is usually performed on the patient's nose and throat (sample). This sample was evaluated using the same method as the pregnancy test. Give the results within about an hour after the screening test, so that patients can get the result quickly. Antigen testing on Reseintyg365 takes place correctly according to the Swedish Public Health Agency's recommendations with an EU-approved antigen kit. Polymerase chain reaction (PCR) can detect COVID-19 even in those without symptoms, which is true in about one third of patients who are ill. However, we know that there are certain conditions for the speed and specificity of antigen testing to be used to obtain a good replacement for PCR. For example, a group test for companies or event staff, why not the whole school.
