Due to the outbreak, "nucleic acid testing" has become one of the most familiar terms. Do you need to draw blood? Does it hurt? What do the test results mean? Let's take a look with me
Nucleic acid test specimens can be collected from deep sputum, nasopharyngeal swabs and oropharyngeal swabs. The oropharyngeal swab and nasopharyngeal swab are collectively known as pharyngeal swabs, with the oropharyngeal swab being taken through the mouth and the nasopharyngeal swab through the nose. (Oropharyngeal swabs are generally collected)
Nasopharyngeal swabs: before collecting nasopharyngeal swabs the detector should inform the collection personnel whether the nasal septum is curved and the history of nasal surgery, during the process there may be a sore and itchy sensation in the nose and stimulate sneezing, which can be immediately covered with tissue or elbow; a small amount of nasal bleeding may occur after nasopharyngeal swab collection, which generally does not require special treatment, if the bleeding is more, please go to the hospital for treatment in a timely manner.
Oropharyngeal swabs: when collecting oropharyngeal swabs, the detector's head is tilted back and the mouth is opened to make an "ah" sound, which helps to expose the throat, but the process may cause an irritating dry cough, nausea, vomiting and other symptoms, the detector can cooperate with the collection staff to try to relax and breathe deeply; hand hygiene needs to be paid attention to before and after the nucleic acid test, you can use a hand-free disinfectant or no-wash Alcohol wipe hands.
Tips: Avoid eating 2 hours before the nucleic acid test to avoid vomiting; do not smoke, drink alcohol, chew gum, etc. 30 minutes before the sample; testers need to wear the correct mask, remove the mask before the test and wear it immediately after the test, prepare a spare mask to facilitate replacement at any time after contamination.
