The new crown epidemic is a matter of public defence that we can’t avoid and can’t hide from.
I believe everyone knows the impact of the new crown epidemic on us.
I believe you all know the impact of the new crown epidemic on us.
As the number of COVID-19 cases across the country starts to climb again.
Everyone has started to discuss it again, and I believe that no topic can attract the attention of the world for such a long time like our current global new crown virus.
Some of us have raised such a question, why do we have two detection methods for nucleic acid detection points.
One is for extraction in the nose, and the other is for extraction in the mouth?
Nasopharyngeal swabs and oropharyngeal swabs only take different paths.
The oropharyngeal swab is to collect oropharyngeal specimens by entering the sampling swab through the mouth.
The nasopharyngeal swab is to collect nasopharyngeal specimens through the nose.
The is a matter of public defence that we can’t avoid and can’t hide from.

Nasopharyngeal swabbing is generally the preferred method of specimen collection for COVID-19 testing.

2. How to effectively collect nasal samples for patients
- Place the entire tip of the swab into the nose and rub one side of the swab as much as possible against the wall of the nostril (also called the anterior nostril) with moderate pressure.
- Use the same cotton swab to do four to five sweeps in each nostril for about 10-15 seconds per nostril. Both nostrils should be swabbed in order to collect an adequate sample.
- Simply swirling the swab into the inner part of the nose or leaving the swab in the nose for 10-15 seconds is an inappropriate technique and may result in insufficient sample.
3. Features and advantages of disposable virus sampling tube (pharyngeal swab)
- High safety: medical materials, good airtightness, good stability, prevent leakage and ensure biological safety
- Various options: nasal/pharyngeal swab + inactivated/non-inactivated preservation solution to meet different experimental needs
- High-efficiency inactivation: high-quality formula can inactivate viruses quickly and efficiently, avoiding the risk of aerosol infection
- Nucleic acid stability: The preservation solution contains special stable components to ensure the stability and integrity of viral nucleic acids during in vitro storage and transportation
- Easy to operate: independent disposable packaging, no need to refrigerate, and can be transported at room temperature
4. About flocked swabs
- The total length is 15CM, the breaking point of the throat swab is 3CM, and the breaking point of the nasal swab is 8CM;
- Virus sampling for oral and nasal cavity;
- Unique jet nylon villi implantation technology increases sample collection and release;
- No sample residue, complete and rapid release of samples;
- 15cm lengthened processing, easy to obtain materials, avoid the risk of contamination;
- Individually aseptic packaging for individual servings for easy handling and transportation;
