Sampling for COVID-19 Testing: Introduction to Nasal Swabs, Pharyngeal Swabs, Nasopharyngeal Swabs
1. Material introduction:
1. Flocked swab: It is made of nylon fibre crowding modern technology, and also the front end is coated with nylon brief fibres repaired in a vertical manner so that there is no absorption hole in the whole tasting area of the tasting swab. As well as the sampling example, will certainly not be scattered as well as preserved in the fibers. Which promotes much faster and also a lot more efficient elution. Traditional cotton swabs can not entirely collect and also elute samples, while flocked swabs can elute 95% of examples. widely used.

2. Cotton Swab: The cotton bud is made from sterilized cotton wrapped around a wooden stick or a plastic pole. Because the all-natural product of cotton has a reduced release rate to the example, and also several of the natural fatty acids in it will harm microbes, the, even more, are much less as well as much less used for sample collection.
3. Rayon Head Swab: Rayon is a synthetic fiber made from wood pulp. Although categorized as an artificial fibre, it is basically a natural material. It is often the standard for diagnostic testing.
4. Polyester Fibre Head Swab: The head product of the polyester fiber swab is made from polyester long fiber winding, which was very first presented in the field of medical screening by DuPont. Polyester fibres for microbial collection, rapid diagnostics, and also PCR screening. Swabs have a high launch price yet are extra expensive than cotton and also rayon swabs.
5. Foam Tip Swabs: Swabs made of medical quality polyurethane are superb materials for diagnosis, especially for cell sampling. This product has great absorption of hydrophilic substances and inadequate absorption of hydrophobic compounds. For some circumstances that need resistance to chemical rust, and also for DNA as well as microbial testing.
2. Introduction of sampling site:
Nasal Swab: Sampling of the nasal cavity.
Throat swab: Sampling of the throat area.
Nasopharyngeal swab: Sampling from the nasal cavity to the throat.
3. Safety factor and material:
Ordinary people can operate it. The new crown self-test products on the market generally use nasal swabs, and Foam Tip fibre heads are the first choice.
Throat swab: Professional operation is required, because the throat is more prone to injury, flocking swabs are the first choice.
Professionals must operate it, and it needs to be very careful from the nose to the throat. Generally, Westerners are easier to accept, while Orientals are less acceptable.
