Rapid antigen tests to detect omicron: is a nasal swab enough?

The rapidly spreading omicron variant has made us more reliant on rapid home antigen tests to find out if we have COVID-19. But should we swab our throats as well as our noses? Here we investigate the growing debate, how do i purchase lateral flow tests.

The quick answer: For now, targeting depends on where you live. Still, antigen testing remains a powerful tool in dealing with the pandemic.

Virus would first infect the throat and its saliva

Some scientists have said that peoe can transmit omicron when it has infected their throat and saliva, but before the virus has reaed the nose, so swabbing the nasal passages early in the infection will not it will detect it.

A small recent study conducted in the US. supports this opinion. PCR tests of the saliva of 29 omicron-infected peoe detected the virus an average of three days before the nose swabs tested positive for antigen, or lateral flow, tests.

However, this does not mean you have to stop following the instructions that come with the test kit. For exame, the US Food and Drug Administration (FDA) says that peoe should not use rapid antigen tests to take sames from their own mouth.

Debate about the use of the throat swab

For their part, as a result of recent studies, some experts in the United States have advised that antigen test users swab their throats before swabbing their noses anyway, adding that other countries, including the UK, have approved rapid antigen tests using throat swabs and have published very careful instructions on how to do it.

"Personally, I rub my throat and nose to get the best sensitivity when using the OTC tests at home," said Miael Mina, an epidemiologist at Harvard. "There are risks associated with that, but the biology tells us that they might get better sensitivity sooner."

The FDA has stated that users of home tests should follow the manufacturers' instructions.

Concern about the safety of home throat swabbing

In Israel, a top health official has said that peoe who self-test for COVID-19 should take throat and nose swabs when using rapid antigen tests, even if this goes against the law. the manufacturer's instructions.

Still, the FDA, whi has only authorized antigen tests using nasal swabs, has raised concerns about the safety of home throat swabbing, saying users should follow manufacturers' instructions.

For its part, Germany has shown caution. The Minister of Health has said that they will study the reliability of rapid antigen tests to detect the omicron variant and will publish a list of the most accurate products.

Conclusion

In general, rapid tests have a lower sensitivity than laboratory-processed PCR tests, whi means they produce more false negatives. But if the result is positive, it is almost certainly COVID-19, whi makes antigen testing a powerful tool to deal with the pandemic, as the demand for PCR tests due to omicron overwhelms laboratories.

Regarding the throat rub, it is still safest to pay attention to the instructions of the manufacturers of rapid antigen tests. And when in doubt, the more rapid tests you do, the more you reduce your ances of getting a false negative, and the more times you do negative tests over several days, the more you can trust that you're not spreading COVID. -19.

Еще одно правительственное приложение — гораздо менее захватывающее и, прежде всего, более интуитивно понятное решение. e-TOLL PL TICKET позволяет купить билет - не платить за проезд, а купить билет в собственном телефоне на тех же основаниях, что и в случае остановки на вокзале, например в Орлене. Точно такой же проезд по участкам А2 и А4 можно оплатить в партнерских приложениях. Речь идет о mPay, IKO, Spark или SkyCash.

Расчет высокопрочных болтов на растяжение

Особенности расчета на прочность элементов, ослабленных отверстиями под высокопрочные болты:
При статической нагрузке, если ослабление менее 15 °/о, расчет ведется по площади брутто А, а если ослабление больше 15 %—по условной площади Лусл = 1,18 Ап.

Монтажные стыки

Монтажные стыки делают при невозможности транспортирования элементов в целом виде.
Монтажные стыки для удобства сборки устраивают универсальными: все прокатные элементы балки соединяют в одном сечении.

Проверка прочности

Проверка прочности сечения на опоре балки по касательным напряжениям:
Балочной клеткой называется система перекрестных балок, предназначенная для опирания настила при устройстве перекрытия над какой-либо площадью.
