病毒式社交媒體帖子稱擦拭喉嚨會產生更準確的 COVID-19 測試. 美國食品和藥物管理局警告說它可能很危險.
奧斯汀, 得克薩斯州——在社交媒體上掀起一股潮流之後, 美國. 食品和藥物管理局 (食品藥品監督管理局) 警告有關在家中進行 COVID-19 測試時擦拭喉嚨的安全問題.
在整個大流行期間, many at-home tests required swabbing nostrils for COVID-19. Other tests have included saliva in a tube, a less invasive nose swab and others.
然而, with the new omicron variant, some experts are recommending those being tested also swab their throats. This comes after the FDA said at-home COVID-19 test have reduced sensitivity to omicron.
Since then, adding 咽拭子 to self-administered tests has gained attention on social media. Epidemiologist Michael Mina retweeted someone who tested negative multiple times through 鼻拭子 tests but then tested positive when adding a throat swab.
He posted on Twitter saying that symptoms start early with omicron, and there’s a chance the virus isn’t growing in the nose but could start further down in places like the throat. 所以, he recommends adding a throat swab.
然而, the FDA cautions against this advice.
In a statement to KVUE, they said the COVID-19 test should be used as the instructions state.
“The FDA advises that COVID-19 tests should be used as authorized, including following their instructions for use regarding obtaining the sample for testing,” said a spokesperson for the agency. “The FDA has noted safety concerns regarding self-collection of throat swabs, as they are more complicated than nasal swabs – and if used incorrectly, can cause harm to the patient. The CDC recommends that throat swabs be collected by a trained healthcare provider.”
