This makes many consumers at a loss. They sometimes find that pharyngeal swabs produce positive results, while nasal swabs do not. Some people simply test their nose and throat at the same time in order to get more satisfactory results.
However, the FDA believes that there is no data to suggest that pharyngeal swabs are a better and accurate method for home testing. The agency is also concerned that people who make their own throat swabs may hurt themselves because it is more complex than nasal swabs.
According to the Wall Street Journal on Tuesday, "We will continue to monitor and evaluate [the situation]," said a spokesman for the production of home rapid test boxes 。 Our test is currently only applicable to nasal use. However, the British and Israeli governments believe that it is not particularly difficult for people to wipe their throats at home for the new crown test. The British government publicly supports this method and has specially produced an operation video to show people how to test the combination of the two methods. Similarly, Israel supports both pharyngeal and nasal swab techniques.
Research shows that Omicron virus may be detected in saliva before it can be detected in the nose. Scientists believe that this is because the virus replicates earliest and fastest in the throat. Therefore, sore throat is a common first symptom of people infected with the virus.
