What material is forbidden for throat swab?

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 best flocked swabs in China

The best-flocked swabs in China

We all know that the development of medical enterprises is of great help to society, especially as China’s medical technology improves, the international community has become more concerned about the products involved in China’s medical technology.

Maybe a few years ago, you might still think that medical consumables like flocked swabs that directly contact the sampling site may not be safe to buy in China. May still be biased towards importing abroad, after all, CDC is very strict in the production of flocked sampling swabs. However, the National Health and Medical Commission of my country also has clear requirements for swab materials in the “New Coronary Pneumonia Laboratory Testing Technical Guidelines (Third Edition)”. In addition, the State Council clearly stated in the “Reform Plan for Governance of High-Value Medical Consumables” that “Improve the supervision and management mechanism, and severely investigate and deal with violations of laws and regulations. Improve quality management, strict pre-marketing registration approvals, establish a product information traceability system, and production companies are responsible for lifelong product quality system;”.

flocked swabs are the latest development trend of disposable sample collection equipment. Flocking refers to the use of “spraying technology” to vertically attach millions of nylon fibers to a handle made of ABS material for medical use through electrostatic charges during the flocking process.

In order to improve sample collection, flocking swabs are divided into different types, such as throat swabs, DNA test swabs, gynecological cervical sampling swabs, anal swabs, microbial sampling swabs and so on.
flocked swabs have clear advantages for many applications. According to the research of laboratory professionals, the flocking swab produced by Shenzhen Huachenyang Technology Co., Ltd. has the following five advantages:

(1) Huachenyang’s flocked swab can provide the best sampling:The best flocked swabs in China
Huachenyang’s flocked swabs are a good choice for rapid diagnostic tests because they can better collect cells or organisms at the collection site. And can ensure the rapid release of the entire cell. Huachenyang flocking swabs ensure a higher sampling rate due to its unique manufacturing process.
(2) Huachenyang’s flocked swab can enhance the sensitivity of diagnosis:
Huachenyang has a professional flocking technology to turn each strand of fiber into a velvety brush, thus creating hundreds of thousands of contact points for better collection and release of specimen samples, compared with non-aggregated swabs, because The increase in the number of target cells helps to improve the sensitivity of rapid diagnostic tests.
(3) Huachenyang’s flocked swabs can wash samples quickly
Aggregate swabs are fully integrated processing (which means they do not contain internal fabrics or other cores to absorb the specimen, that is, they will not intercept the sample in the fiber), which not only can collect and retain more samples, but also provides more A good sample collection rate can also release the complete sample into the preservation solution or medium more quickly and completely. The sample is close to the surface, and the sample can be eluted more quickly and completely.
(4) Huachenyang’s exclusive multi-length flocked fiber for flocked swabs
Huachenyang(Shenzhen ) Technology Co., Ltd is not the only manufacturer of medical consumables that provides flocked swabs, but we are the most diligent and sincere wanting to make flocking swabs of the highest quality and the most exquisite style, which is better than traditional cotton, polyester or rayon. The swab collects and retains more specimens.
(5) Huachenyang’s flocked swab has a unique design to facilitate handling and transportation
The flocked swabs we produce have unique breaking points, so you can easily break off the swab tail that grows out of the nozzle by leaning the swab against the nozzle of the virus sampling tube after sampling. Tighten the cap to see it can be safely transported and stored.
Huachenyang(Shenzhen ) Technology Co., Ltd. has always strictly required its own products with the highest production quality standards and is committed to becoming the best manufacturer of flocked swabs in China.


What to use a flocking sampling swab?

What to use a flocking sampling swab?

Maybe you have such a question in your mind, why use flocking sampling swabs? After reading this article, you may know the answer

Reasons for using flocking swabs:

In our traditional fiber swabs, the sample is not only intercepted by the fiber mass gap, which makes the sample permeate, dilute and intercept in the fiber, but also slows down the collection and release speed.

Nylon flocking swab not only has good sample collection and release capacity, but also has a release rate of more than 80%.

Generally speaking, the sampling time of flocking swabs is 3-5 seconds, while that of cotton swabs is 15-120 seconds, or even longer. This in the diagnosis process, caused serious pressure on the staff. Only faster sample extraction can complete the collection and analysis more efficiently.

The characteristics of huachenyang flocking swabs were as follows

(1) The swab was make by spraying dense nylon fiber technology.

(2) According to the analysis items, there are soft or brush like swabs, which have reach the maximum collection amount.

(3) Disposable sterile injection swab with break point.

(4) Flocking swab technology can improve the adsorption / release amount of samples and improve the sensitivity of analysis

(5) No sample rejection indicates that the specimen can be delivere faster and less.

(the upright nylon fiber is like a soft brush, which can not only collect more cell samples.

Moreover, the capillary effect between nylon fibers enhances the bearing capacity of water-based samples.

Moreover, the samples are concentrate on the surface of the swab, which is easier to elute.

More samples can be adsorbe by nylon swabs.)

transport medium

transport medium

Transport media are essentially solutions of buffers with carbohydrates, peptones and other nutrients (excluding growth factors) designed to preserve the viability of bacteria during transport without allowing their multiplication. The primary objective of the use of the transport medium is to maintain the specimen as near its original state as possible.

Transport medium aims to preserve a specimen and minimize bacterial overgrowth from the time of collection to the processing of the specimen. Depending on the type of organisms suspected in the sample, transport media may vary.

However, in general, transport media are classified on the basis of the physical state as semi-solid and liquid and also on the basis of their utility as bacterial or viral transport media.

What does transport media contain?

  • Contains only buffers and salt.
  • Doesn’t contain any nutritional ingredients such as carbon, nitrogen, and organic growth factors so as to prevent microbial multiplication.
  • Addition of antibiotics and other substances like glycerol may be added for transporting specimens for tissue culture.

What samples are collected in transport medium?

All types of samples that may contain pathogens but could not be processed immediately requires a transport medium. It may be Stool, urethral swabs, Nasal and throat swabs and specimens for tissue culture etc.

What does huachenyang produce? I guess you don’t know

transport mediumfo

Given below are some examples of transport medium with their purpose:

Cary and Blair Medium: semi-solid, white colored transport medium for faeces that may contain Salmonella, Shigella, Vibrio or Cam­pylobacter
Amies medium with charcoal: Charcoal helps eliminate metabolic products of bacterial growth, which may be especially useful in the isolation of fastidious organisms like However it is suggested that, some other pathogens like Campylobacter can also survive in such medium.
Amies medium without charcoal: Are ideal for the isolation of Mycoplasma and Ureaplasma
Stuarts medium: Commonly used for transporting specimens suspected of having gonococci. Also used for transporting Throat, wound and skin swabs that may contain fastidious organisms.
Venkatraman Ramakrishnan (VR) medium: Used to transport feces from suspected cholera patients.
Sach’s buffered glycerol saline: Used to transport faeces from patients suspected to be suffering from bacillary dysentery.
Viral Transport Medium: Viral Transport Medium (VTM) is ideal for diagnosis of viral infection. Ocular, respiratory and tissue swabs can be submitted in this medium. Fluid samples such as tracheal wash specimens or peritoneal fluid should be submitted as is, in sterile vials which prevent desiccation. In the absence of viral transport medium, submit swabs in sterile, sealed vials with several drops of saline added, to prevent desiccation. Cotton, plastic, wood-handled, and Dacron and other synthetic swabs are all acceptable. Calcium alginate swabs should be avoided. Bacterial transport media are not appropriate for virology.
Anaerobic Transport Medium (ATM): is a mineral salt base semi-solid media with reducing agents designed as a holding medium for maintaining the viability of anaerobic bacteria It contains buffered mineral salts in a semi-solid media with sodium thioglycolate and cysteine added to provide a reduced environment. Resazurin may also be added as a redox indicator to reveal exposure to oxygen by turning pink. It provides an environment, which maintains the viability of most microorganisms without significant multiplication and allows for dilution of inhibitors present in clinical material. Examples include thioglycolate broth

Methods: virus swab specimens were collected

Methods: virus swab specimens were collecte

We all know that the collection method of virus swab specimen is basically to use the swab to sample the infecte place or part of the virus, and then put it into the virus sampling tube containing preservation solution without touching other places, so as to conduct virus detection later. So basically, the soup is change without changing the dressing.

For example, throat swabs and nasal swabs were use to detect new coronavirus

Methods: throat swabs were collected

Inform the patient of the purpose of examination, collection method and collection time. It is best to collect specimens before using antibiotics.


To study the clinical effect of the method

Secretions were collecte from pharynx or tonsil for bacterial culture or virus isolation to assist in clinical diagnosis and treatment.

Prepare sampling supplies:

Disposable sampling swab, virus sampling tube, tongue depressor and biological bag

Operation method:

(1) Ask the patient to sit down, tilt his head back, open his mouth and make a “ah ~” sound

(2) The patient’s tongue was fix with a tongue depressor, and a disposable swab was used to cross the tongue base to the posterior pharyngeal wall, tonsil recess and lateral wall;

(3) Repeatedly wipe 3-5 times to collect mucous membrane cells or sputum

(4) . gently remove the swab to avoid touching the tongue, the suspension, the oral mucosa and saliva

(5) Put the swab into the virus sampling tube gently and vertically. Break off the tail of the swab, and leave the tail of the swab so that it is completely place in the tube. Be careful that the swab does not touch the wall of the tube.

(6) . tighten the cap, mark it, and seal it in the biosafety bag.

(7) It should be sent to the laboratory for testing in time. If it can not be sent for inspection in time, it should be store at low temperature.

Methods: nasal swabs were collecte

(1) Ask the patient to sit down with his head slightly back and remove the secretion from the front nostril first;

(2) . measure the distance from nostril to ear base with swab and mark with finger

(3) . gently insert the swab into the nostril until it is marke or stopp when there is obstruction. Let the swab stay in the nose for 15-30 seconds, and then rotate it gently three times.

(4) . slowly pull out the nasal swab and quickly put it into the virus sampling tube. Then break the swab, leave its tail and place it completely in the tube.

(5) . tighten the cap, mark it, and seal it in the biosafety bag.

(6) If it is necessary to collect from two nostrils, one swab should be used.

(7) It should be sent to the laboratory for testing in time. If it can not be sent for inspection in time, it should be store at low temperature.
