Which of the following diseases can be used for throat swab collection?

Which of the following diseases can be used for throat swab collection?

We are no strangers to throat swabs, but do you know which diseases it applies to? Take a look.

Generally, the pharyngeal isthmus has beneficial bacteria:

In general, the shaping of the pharyngeal isthmus requires all normal and beneficial bacteria in the oral cavity without the growth and development of pathogenic bacteria. The germs in the throat are all from the outside, and they do not get sick under normal conditions, but infections and other external factors can cause illnesses such as infections under the body or part of the immune system. Therefore, bacterial culture of throat swabs can isolate pathogenic bacteria, which is conducive to the diagnosis of diphtheria, purulent tonsillitis and acute pharyngitis.

What diseases can throat swab collection apply to?

Pharyngeal swabs are often use clinically to check bacterial or fungal inflammation of the throat, such as chronic pharyngitis, mycoplasma infection, candidal pharyngitis, diphtheria, suppurative tonsillitis, and acute pharyngitis.

Pharyngeal swabs are mainly use for bacterial culture to identify the pathogens of the above diseases. When the patient has repeated pharyngeal pain, pharyngeal discomfort, itching, painful swallowing and other symptoms.

Clinical manifestations:

Patients will experience repeated throat pain, pharyngeal discomfort, itching, painful swallowing. In severe cases, they will have slow onset, headache, fatigue, fever, cough, and a small amount of sticky sputum. Sometimes they will continue to have a high fever or even loss of appetite. symptom.

If pathogenic bacteria are detecte in the throat swab secretion, it is an infection:

When pathogenic bacteria are detecte in sputum and throat swab secretions, it is regard as a respiratory infection. Cooperate with other inspections (such as X-ray fluoroscopy, B-ultrasound, etc.) to confirm the location of the respiratory system infection. Common pathogens for respiratory infections include: Staphylococcus, Pneumococcus, Haemophilus influenzae, Klebsiella pneumoniae, Staphylococcus, Streptococcus infection, Pseudomonas aeruginosa, Escherichia coli, etc.
If tuberculosis is shaped, it is tuberculosis. If you create a yeast-like yeast, you should consider whether the antibiotics are not use well or too much during the infection period. The antibiotics should be stop immediately and replace with antifungal drugs, such as amphotericin B, griseofulvin, clotrimazole suppository, etc.

Operation method of throat swab:

① Check the doctor’s order and be prepare.

②. Ask the patient to rinse his mouth with clean water, then let the patient open his mouth to make an “ah” sound, and use a tongue depressor if necessary.

③. Take out the disposable sampling swab, gently and quickly wipe the two palatal arches, tonsils and posterior pharynx three times.

④ Put the swab head vertically to avoid contamination of the tube wall, forcefully break off the tail of the swab at the mouth of the sampling tube, discard the tail, tighten and cover the tube cap (strictly perform aseptic operation)

⑤ After sampling, check the patient’s name again.

⑥. Indicate the retention time of the specimen and submit it for inspection in time.

Points to note:

①. When putting the swab into the tube, it should be place vertically, not to wipe it to the bottle mouth to avoid contamination. When placing it in the transfer box, it should be place vertically to avoid leakage.

② It is best to send/sent to the laboratory for inspection on the day of sampling.

③. Appropriate specimens must be consistent with the inspection form before inspection. The appearance of the sampling tube must be clear and well-known and basic information. Specimens without basic information cannot be tested; specimens submitted for inspection must be submitted (or electronically submitted in advance). , Submit inspection form and other materials. The submitted materials should be ensured not to be contaminat and not to be put together with the specimen.

④. In order to prevent sectioning when sampling, it should be avoide within 2 hours after the patient has eaten. The collection action is gentle, stable and agile to prevent discomfort to the patient.

⑤. The throat swab should not touch other parts during the collection process to ensure the accuracy of the remaining specimens.

⑥. When you decide to do a throat swab, please do not use antibacterial drugs.

⑦. The depth of throat swab collection and the length of mucosal contact time. When collecting throat swabs, if the subject’s vomiting reaction is relatively large, the sampling time is not enough or the inferior quality swabs are use, which may cause false negatives and delay treatment.

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.

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

What is the transmission 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.

The transport medium not only protects the specimen, but also minimizes the overgrowth of bacteria from the collection to the processing of the specimen.

Depending on the type of organisms suspect 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 add 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 process 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

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

Cary and Blair Medium: semi-solid, white color 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 suspecte of having gonococci.

Also use for transporting Throat, wound and skin swabs that may contain fastidious organisms.

Venkatraman Ramakrishnan (VR) medium:

Use to transport feces from suspecte cholera patients.

Sach’s buffered glycerol saline:

Used to transport faeces from patients suspecte 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 submit in this medium.

Fluid samples such as tracheal wash specimens or peritoneal fluid should be submit as is, in sterile vials which prevent desiccation.

In the absence of a virus transport medium, not only can the swab be placed in a sterile sealed vial, but also a few drops of saline can be added to prevent drying.

Cotton, plastic, wooden handle, polyester and other synthetic cotton swabs are all acceptable.

However, calcium alginate swabs should be avoided. Bacterial transport media are not suitable for virology.

Anaerobic Transport Medium (ATM):

It is not only a mineral salt semi-solid medium containing reducing agents, but also designed to maintain the activity of anaerobic bacteria.

It contains not only buffer mineral salts, but also sodium mercaptoacetate and cysteine to provide a reducing environment.

Resazurin may also be add as a redox indicator to reveal exposure to oxygen by turning pink.

It provides an environment that can not only maintain the viability of most microorganisms without mass reproduction, but also dilute inhibitors present in clinical materials. Examples include thioglycolate broth

What are the requirements for sampling swabs

What are the requirements for sampling swabs

Since the outbreak of the epidemic,

The virus sampling tube and nucleic acid test throat swab have been pushed to the cusp of the storm.

Many people worry that irregular sampling swabs will cause false positives or false negatives.

Because this will not only threaten personal safety but also cause great harm to society, the result will be very serious.

so the National Health Commission issue the “New Coronary Pneumonia Laboratory Testing Technical Guidelines (Third Edition)” in the specification requirements: (The original text is quote here)

China’s requirements for sampling swabs:

Pharyngeal swab: Use two plastic rod swabs with polypropylene fiber heads to wipe both pharyngeal tonsils and posterior pharyngeal wall at the same time,

and immerse the swab head in 3mL virus preservation solution (isotonic saline solution, tissue culture solution or Phosphate buffer solution),

discard the tail, and screw the cap tightly.

Have you see that the clear material requirements for swabs in my country’s guidelines require polypropylene fiber,

but the manufacturer that produces swabs needs to pay attention to not using wooden stick swabs and calcium alginate swabs.

Why What? Please look down

U.S. requirements for sampling swabs:

Let’s take a look at the requirements for sampling swabs use in the collection of nasal and pharynx samples in “InterimGuidelines for Collecting,

Handling, and Testing Clinical Specimens from Patients Under Investment (PUIs) for 2019NovelCoronavirus (2019-nCoV)” issued by the United States CDC.

The original text is: Use only synthetic fiber swabs with plastic shafts .

Do not use calcium alginate swabs or swabs with woodeen shafts,

as they may contain substance that inactivate some viruses and inhibit PCR testing.

Place swabs immediately into sterile tubes

The translation is: only synthetic fiber swabs with plastic rods can be use.

Calcium alginate swabs or wooden stick swabs cannot be used,

because they may contain substances that inactivate certain viruses and inhibit PCR detection.

to sum up:

We all know that the United States CDC has high requirements for the materials of medical devices,

and this time is no exception, and it explains why wooden stick swabs and calcium alginate swabs cannot be used.

China also has clear regulations on sampling swabs, so manufacturers must not be sloppy in this regard.

Nasopharyngeal swab

Nasopharyngeal swab

What is a nasopharyngeal swab?

Nasopharyngeal swabs are actually relatively long sampling swabs.

Not only are relatively long disinfection sampling swabs, but their main function is to use nasopharyngeal secretions for bacterial culture and drug sensitivity testing.. Through bacterial culture and drug sensitivity test, the source of infection in the nasopharynx and the microbes in the nasopharynx can be selected,

and then a drug sensitivity test can be done to determine which drugs are sensitive,

so that sensitive drugs can be selected for treatment, so as to achieve better results Effectiveness,

so the nasopharyngeal swab is actually a sampling swab for taking tissue samples.

Nasopharyngeal swab specimen collection

Nasal swab collection method

purpose

Normal people’s pharyngeal isthmus culture should have normal oral flora without the growth of pathogenic bacteria. The bacteria in the pharynx all come from the outside world and do not cause disease under normal circumstances, but infections can occur under the body’s systemic or local resistance and other external factors to cause diseases. Therefore, pharyngeal swab bacterial culture can isolate pathogenic bacteria, which is helpful for the diagnosis of diphtheria, suppurative tonsillitis, and acute pharyngitis.

Nasal swab collection method

①. Ask the patient to keep his head still and remove the secretions on the surface of the anterior nasal cavity. The collector can stand on the side of the collector, reducing occupational exposure caused by coughing and sneezing, and alleviating the pressure on the collector.

②. Measure the distance from the nostril to the root of the ear with a swab and mark with your hand.

③. Gently insert the swab into the nostril in the direction perpendicular to the nose (face) through the nasal cavity, with a feeling of touching the wall until the finger touches the nose, keep the swab in the nose for 15-30 seconds, and then gently rotate it 3 times.

④. Put the swab into the virus transport medium, not only to break the swab stick, but also to put it completely into the test tube.

⑤. Tighten the cap of the tube, mark it, put it in a plastic bag and seal it.

⑥. Submit the specimens for inspection in time
