Nucleic acid testing is used as a basis for pathogenic diagnosis and is currently the most important basis for confirming the diagnosis. According to experts from the CDC, our respiratory tract is divided into the upper respiratory tract and lower respiratory tract, with the upper respiratory tract including the nose, pharynx and larynx. The lower respiratory tract includes the trachea, bronchi, and lungs. Medically, the cricoid cartilage is used as the boundary to distinguish. Specimens for nucleic acid testing can be collected from deep sputum, nasopharyngeal swabs, and oropharyngeal swabs. The oropharyngeal swab and nasopharyngeal swab are collectively referred to as pharyngeal swabs, with the transoral being the oropharyngeal swab and the transnasal being the nasopharyngeal swab. Currently, most hospitals use oropharyngeal swabs to take specimens, which are easy to collect and less painful.
It is recommended that you should pay attention to these things before taking a pharyngeal swab.
During the queuing process, it is recommended that you bring some water with you. Due to the hot weather, you need to try to keep the throat moist before the examination to facilitate collection, so you can drink a small amount of water before collection.
Because samples to be collected from the throat may cause a little discomfort, it is not recommended to do so after a full meal or alcohol consumption, and you should not smoke, drink, chew gum, etc. 30 minutes before sampling.
To improve the accuracy of the results, it is recommended to wear a mask to cover the nose and mouth before sampling and cough and then tilt your head slightly to cooperate with the doctor and say "Ah~" in a long voice.
There may be a sense of vomiting during the collection, but do not spit anywhere. It is recommended that you bring paper along with you, spit in the paper wrapped well and put it in the unified garbage can for disinfection. After arriving home has been good personal disinfection, such as hand washing, laundry, etc.
