Oral Swab Stick-Oropharyngeal sampling swab.
COVID-19 Oral Swab test is an important reference for diagnosis and evaluation of curative effect of new crown pneumonia.
Nucleic acid screening samples mainly come from deep cough sputum or pharyngeal swabs.
Pharyngeal swabs include nasopharyngeal swabs and oropharyngeal swabs.
The results of COVID-19 nucleic acid test are also useful.
What is the key to the collection of nucleic acid test specimens from pharyngeal swabs?
Whether collecting nasopharyngeal swabs or oropharyngeal swabs, the collection depth is the key.
For example, if the nasopharyngeal swabs are not collected deep in the nasal cavity, most of the cells that may be collected are virus-free cells, which may cause “false negative”.
What is the difference between Oral Swab Stick and Nasal Swab?
Pharyngeal division includes nasopharynx, oropharynx and laryngopharynx. The mucosa of the three is continuous and belongs to the area of upper respiratory tract. The sampling path of nasopharyngeal swab and oropharyngeal swab is different. Oral sampling is oropharyngeal swab and nasal sampling is nasopharyngeal swab.
What are the advantages of nasopharyngeal swabs?
It can stay in the pharynx for a long time in order to obtain more sufficient specimens; The exposure risk of the sampler is lower than that of the oropharyngeal swab, because the sampler can stand behind the patient’s side during sampling, and the patient is required to pull down the mask to expose only the nostrils and cover the mouth without looking directly at the patient’s mouth, and there is basically no pharyngeal reflex. A few patients may have sneezing reflex after sampling, and the patient can be covered with elbows or paper towels, And because the sampler is not directly in front of the patient, the exposure risk is quite low, so the psychological pressure of the sampler will not be so great.
Can a positive oral swab stick confirm COVID-19?
The novel coronavirus novel coronavirus infection can be diagnosed by the new swab positive guide for new coronavirus infection, but it does not necessarily indicate pneumonia.
After infection with COVID-19, the old person may show two different infections, including fever, dry cough, weakness, and asymptomatic infection.
Patients with positive nucleic acid test of new crown must be isolated and treated.
Only when nucleic acid is negative for more than 24 hours, body temperature is normal and pneumonia symptoms disappear can isolation be lifted according to the situation.
How to sample oropharyngeal swabs?
First collect the oropharynx, gently and repeatedly wipe it for more than 3 times, and then collect the depth of the throat wall for more than 3 times.
The whole process takes about a few seconds. It may be a little disgusting, but there won’t be too many reactions. It’s more acceptable.
According to the personal experience of colleagues: slightly disgusting, but completely acceptable
The site experienced the collection of oropharyngeal swabs. The whole sampling process is only a few seconds and there is almost no discomfort.
