What material is forbidden for throat swab?

We all know that the material of medical swabs has always been the focus of attention. After all, medical swabs are directly in contact with the skin. It’s OK to contact the skin with alcohol for disinfection. It’s OK. But what about those that directly contact the organs? For example, the throat swab we are most familiar with during the epidemic.

We know that the throat swab is in direct contact with the sampling site, and the material of the sampling head is closely relate to the subsequent detection.

What kind of material should be use for sampling swab head?

The sampling swab head should be make of PE synthetic fiber or artificial fiber. Calcium alginate sponge or wooden stick swab (including bamboo stick) should not be use. Cotton products should not be use in the head of swab, because the fiber of cotton has strong adsorption of protein, and it is not easy to elute into the subsequent preservation solution; while the wood stick or bamboo stick containing calcium alginate and wood components is broke and soake in preservation Protein can also be adsorb in the solution and even inhibit the subsequent PCR reaction.

What material can’t be use for sampling swabs? Why?

It is recommend to use synthetic fibers such as PE fiber, polyester fiber and polypropylene fiber to make swab head. Natural fibers such as cotton are not recommend.

Do not use calcium alginate sponge for throat swab material!

Neither calcium alginate additive should be add in the cotton swab handle material, nor the use of wooden stick or bamboo stick is recommend.In a word, the sampling swab should ensure the sampling amount and release amount, and the selecte material should not have substances that affect the subsequent detection.

The difference between traditional fiber wound swabs:

Electron Microscope photograph of traditional fiber winded swab. Electron Microscope photograph of the nylon flocked swab.

With traditional fiber wound swabs a large percentage of the sample

collected remains entrapped in the fiber matrix of the tip.

It has been shown that the flocked swab release up to 95% of the sample

collected compared to 25% in a standard fiber tipped swab -especially

important if the sample size is particularly small.

1. Utilizes unique “spray-on technology” and “electrostatic charge”.

2. Innovation nylon fibers technology.

3. The perpendicular nylon fibers act as a soft brush.

4. Capillary action between the nylon fiber strands facilitates strong hydraulic

uptake of liquid samples.

5. To limit interference and improve consistency the swab is manufactured from completely

inert components.


1. Collecting a large amount of the cells

2. Rapid elution and release of the specimen

3. Unique molded breakpoint design in swab handle

4. Free of any PCR inhibitors and interference


It is used for forensic, laboratory, a diagnostic company, the genetic testing company, drug company, etc.
