Rapid antigen tests
Antigen tests are used for the direct, qualitative detection of coronaviruses. They react to the virus proteins in the patient sample and indicate a positive result in an acute COVID-19 infection. Usually, the sample material is taken from the nasopharynx - but there are now also tests that can be carried out with nasal swabs and nasal self tests swabs
SARS-CoV-2 antigen tests to be performed with nasal smears
The removal of nasopharyngeal smear material is not only unpleasant for the patient, but often also often provokes unwanted reflexes, such as sneezing or coughing, so that the sampling is disturbed. In order to make the test execution more pleasant for the patient and to simplify the learnability of correct sampling, almost all manufacturers have now launched antigen tests on the market, which can be performed with nasal swab samples. With nasal swab, the swab does not need to be pushed forward to the nasopharynx - an penetration depth of about 2 - 4 cm is enough to remove the required material.
However, it is particularly important to adhere exactly to the operating instructions and, as.B in the Panbio™ COVID-19 antigen test (nasal),to guide the swab five times along the nasal mucosa and to perform this in both nostrils. This is the only way to ensure that sufficient sample material (mucus and cells) is available to obtain meaningful test results.
Due to the gentle test method, the nasal SARS-CoV-2 antigen test is particularly suitable for children, elderly patients (e.B. in nursing homes) and with people with disabilities as well as for all patients who have to be tested very often.
The Benefits of Corona Rapid Self-Testing
Corona tests, which can be carried out by the user himself, offer many advantages not only in the private sector, but also within companies, schools and public institutions. While previously the test had to be carried out by a specially trained specialist and the testing capacity was therefore very limited by the time factor, now everyone can carry out the Covid-19 test on themselves from smear to evaluation. As a result, a large number of people can be tested within a short time. The gentle sampling in the anterior nasal area is another important advantage - especially if the test must be carried out at regular intervals.
