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.

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.

Objective:

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.

(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

(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.

Throat swab

Throat swab

What is a throat swab?

A throat swab is a swab use to check whether the throat is disease and to sample the throat.

It can be said to be a detection method for understanding the patient’s condition, oral mucosa and pharynx infection.

Because the pharynx is cause by infections caused by external bacterial infestation when the body’s body or local resistance drops,

the doctor needs to collect some cells or viruses for observation when we seek medical treatment, so as to understand the patient’s disease Illness.

Why use throat swabs for nucleic acid testing of new coronavirus?

① The virus sampling tube needs ACE2 receptor:

Because the new coronavirus is mainly spread through droplets and contact, and there are ACE2 receptors in the respiratory tract that are necessary for the new coronavirus invasion,

the respiratory tract of the infected person is the main gateway for the new coronavirus invasion, so the infecte person will Pneumonia occurred.

②, the initial stage of virus infection

In the early stage of virus infection, if blood is use to detect nucleic acid in such suspected cases, false negatives are likely to occur.

because the blood may not have been infecte by the virus in the early stage of virus infection.

③The throat is the place where the virus infestation is highest

With throat swabs, samples from the patient’s nasopharynx, oral cavity and other lower respiratory tract secretions will have the highest probability of being positive,

so throat swab sampling is the best choice for nucleic acid detection.

④Mature nucleic acid detection technology:

Moreover, the current nucleic acid detection technology is considere to be a relatively mature detection method.

It only needs to wipe the throat area for a few seconds to collect the specimen.

How are throat swabs collecte?

Pharyngeal swab collection method

①. First, check personal information with the subject.

 

②. Then tear off the outer packaging of the sampling swab and take out the sampling swab;

 

③. Let the subject open his mouth to make an ah sound, expose the throat, and if necessary, press the tongue down with a tongue depressor

(lightly press the front 2/3 of the tongue and the back 1/3);

 

④. Take out the sterile swab, gently and quickly wipe the bilateral pharyngeal tonsils and posterior pharyngeal wall 3 times,

put the swab head into the preservation solution,

⑤Strongly buckle off the tail of the swab at the mouth of the preservation tube, discard the tail, tighten and cover the tube cap.

(strictly perform aseptic operation).

⑥. Check the patient’s name again after sampling;

⑦. Put the sample in a sealed bag and a special transfer box, and quickly send the sample to the laboratory for inspection.
