Virus sampling tubes, a set of microbial sampling and transport tubes for sampling influenza virus, hand, foot and mouth virus and other viruses, a set of sampling and transport of centrifuge tubes, also known as specimen transport tubes, has become a commercial product. So do you know how the virus sampling tube is used?
Virus sampling tube sampling is mainly divided into oropharyngeal sampling and nasopharyngeal sampling.
1, oropharyngeal sampling: first press the tongue with a tongue depressor, then the head of the sampling swab into the throat to wipe the bilateral pharyngeal tonsils and the posterior pharyngeal wall, mild force swabbing the posterior pharyngeal wall parts, should avoid touching the tongue.
2、Nasopharynx sampling: measure the distance from the tip of the nose to the earlobe with a swab and mark it with your finger, insert the sampling swab into the nasal cavity in the direction of vertical nose (face), the swab should reach at least half of the length from the earlobe to the tip of the nose, make the swab stay in the nose for 15-30 seconds, gently rotate it 3-5 times and withdraw the swab.
It is easy to see from the use of the method, whether oropharyngeal swabs or nasopharyngeal swabs, sampling is a technical task, difficult and easy to contaminate, the quality of the collected samples is directly related to the subsequent detection, if the collected samples have a low viral load, it is easy to cause false negatives and difficult to confirm the diagnosis.
The use of Medeco's oral disposable swab or nasopharyngeal disposable swab, with molded break points on the rod, is easy to break and save in the sampling tube, and is not easily contaminated.
