Disposable sampling swabs, I believe that we are not unfamiliar with the past two years, because now do nucleic acid testing with more testing tools are disposable sampling swabs, usually we see the most nasal swabs and pharyngeal swabs, we commonly used sampling swabs are flocked swabs, flocked swabs, is a disposable sampling swab composed of nylon short fiber fluffy head and abs plastic rod.
What is the meaning of pharyngeal swab? How to sample pharyngeal swabs? What are the advantages of flocked swabs? Flocked swab is made of nylon fiber flocking technology, the front end is coated with nylon short fibers fixed in a vertical manner, making the entire collection swab collection area without absorption holes, the collected sample will not be scattered and retained in the fibers, which is conducive to faster and more efficient elution.
1- Compared with the traditional winding swab, the flocked swab collects and releases 3 times more samples and does not cause harm to the human body.
2- Flocked swabs collect samples in 3-5 seconds, which is fast and convenient to improve work efficiency. Only faster sample extraction can complete the collection and analysis more efficiently.
3- And through the directional friction effect of the brush-like fiber layer, the cell sample can be captured completely, so the flocked swab is especially beneficial to the collection of micro DNA.
4-After a large number of clinical experiments, it has been shown that flocked swabs have a better effect on the collection and delivery of clinical microbiological specimens compared with ordinary sterile cotton swabs. This is especially true for specimens that cannot be sent in a timely manner and that have been left for too long.
What are the uses of flocked swabs?
Flock swabs are mainly used for oral nasopharyngeal sampling, cervical vaginal sampling, and laboratory testing. Of course, depending on the use, they can also be divided into pharyngeal swabs, oral swabs, DNA swabs, and cervical swabs, which are similar to the above categories, but will be slightly different, and are mainly used by laboratory testing centers and hospitals. In order to limit damage to the sample and improve the accuracy of the test, swabs are made from completely inert components. This makes flocked swabs ideal for PCR work, as they are biocompatible and ideal for PCR work.
Precautions when using flocked sampling swabs for collection.
1, be careful that hands and other objects do not touch the sampling head to avoid contamination of the sampling head and affecting the sampling results.
2, in the 30 minutes before sampling, pay attention not to smoke, do not drink, and do not eat, this point should be noted, otherwise it will also cause a relatively large impact on the sampling results.
3, sampling swabs are disposable supplies, can not be used twice, if the existence of packaging damage, do not continue to use.
