Principales métodos de prueba de Covid-19: dispositivo de recogida de saliva, hisopo nasal y hisopo oral

According to Ye Bingji, Presidente del Comité de Supervisión de la Sociedad de Medicina de Laboratorio de Macao, tanto los hisopos nasofaríngeos como los hisopos orofaríngeos son incómodos, pero los hisopos nasales no sentirán vómitos, y la sensibilidad de la muestra es mayor. It is more important that the inspectors and residents cooperate with each other. The sampling work will be completed more smoothly.

In the global prevention and control of the new coronavirus, viral nucleic acid testing is one of the important measures. The quality of samples taken during the testing process directly affects the test results. According to Ye Bingji’s interview, there are currently three main methods for Covid-19 test sampling, including deep throat saliva (dispositivo de recogida de saliva), nasopharyngeal swab and oral swab. The sampling method depends on the regional epidemic prevention measures.

Throat saliva (dispositivo de recogida de saliva) prueba. The subject coughs up saliva into the sampling bottle. It sounds simple, but it is not just “spitting”. It must be spit out through the oropharynx to contain nasal fluid. In other words, if the tester can only provide Oral saliva may greatly compromise accuracy. Ye Bingji suggested that you should not eat a lot or rinse your mouth before the test, which will affect the test results.

Hisopo nasal, Extienda el hisopo de algodón adjunto al reactivo hacia la cavidad nasal., y raspar la epidermis mucosa varias veces con fuerza moderada. With an oral swab, extend the cotton swab attached to the reagent from the mouth into the pharynx, and scrape the mucous membranes of the bilateral pharyngeal tonsils and laryngopharyngeal wall with moderate force. He believes that the two sampling methods need to stay for a period of time, and the sampling will cause discomfort. Entre ellos, oral sampling will cause nausea and vomiting, while nasal sampling will not, and will not cause mistaking of the detection stick.
