Sample collection swabs

Sample collection swabs are usually made up of the following materials:
Handle: generally made of plastic, such as polypropylene (PP).
Swab head: commonly made of polyester fiber, nylon fiber and so on.
Its characteristics mainly include:
Good adsorption: can effectively collect and adsorb samples.
Flexibility: easy to operate during the sampling process.
Not easy to fall off: to ensure that the fibers of the swab head will not easily fall off during use, to ensure the quality and accuracy of the sample.

The following are general steps for the proper use of a sample collection swab:
Preparation: Make sure your hands are clean, open the package and remove the swab.

Sample collection swabs have the following important applications in virus sampling:
Nasopharyngeal swab sampling: it is used to collect secretions from the nasopharynx and is one of the common sampling methods for new coronavirus testing.
Oropharyngeal Swab Sampling: allows the collection of samples from the oropharynx for virus detection.
Environmental Sampling: Used to collect samples of the virus in the environment, such as public places and surfaces of objects.
Close contact tracing sampling: Helps to identify possible routes of virus transmission and infected persons.
Mass Screening Sampling: Used for mass sampling of the population for virus detection in outbreak prevention and control.
