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.
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.
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.
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.
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.
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.
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 are the benefits of flocking swabs?
We all know that flocked swabs can be used to collect samples. We are a leader in the field of medical swabs,
(1) Flocking swabs are harmless to organisms, and they can increase the collection and release of specimens as much as possible;
(2) A large number of clinical trials have shown that, compared with ordinary sterile cotton swabs, nylon flocked cotton swabs not only have better collection and transportation effects for clinical microbial specimens, but also for those specimens that cannot be submitted for inspection in time and have been placed for too long.
First of all, Huachenyang’s swab not only uses an international medical paper-plastic bag made of medical dialysis paper,
but also an independent package in a large box, which is particularly convenient to use.
Secondly, our swabs can also choose different preservation solutions and sampling tubes for different types of specimens (for example, bacteria, viruses, mycoplasma or chlamydia, etc.).
Furthermore, our swab adopts unique electrostatic spray implantation nylon fiber technology to increase the collection and release of specimens.
Then our fluffy swab can collect more target analytes, and not only has no specimen residues, but also speeds up specimen processing.
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.
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.
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 material is forbid for throat 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
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.
(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.)
What to use a flocking sampling swab?
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
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.
Disposable sampling swab, virus sampling tube, tongue depressor and biological bag
(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.
(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.
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)
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
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.
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 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.
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.
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

Throat swab manufacturer
Now it is October of 2020. As we all know, this year is not a peaceful year. Because of the outbreak of the epidemic, we have brought a lot of inconvenience to our life and work.
Fortunately, the epidemic situation has been controlled in China. Do we still need the throat swabs that were used most frequently before?
First of all, what is the function of throat swab? Used the throat swab examination is mainly to check the throat of diphtheria,
acute suppurative tonsillitis, acute pharyngitis and other important examination methods of pharyngeal diseases.
The specific operation is to press the tongue of the patient with a tongue depressor, take a little throat secretion with a clean swab, and examine it under a microscope.
These secretions can also be used for drug sensitivity test to find harmful bacteria colonized in the throat, providing clinical help for the next step of diagnosis and medication guidance.
Pharyngeal swab examination will have certain discomfort reaction, some patients in the throat swab examination will have mild pharyngeal reflex, but it can be tolerated,
so throat swab examination is very necessary. What’s more, what throat swabs do during the epidemic is to take secretions to check for new coronavirus.
And now it is autumn and winter season, the climate is relatively dry,
there are more children in this season is very easy to appear throat inflammation,
swallowing food throat pain, because of throat inflammation or bronchitis caused by aphasia, nasopharyngitis and a series of symptoms of pharyngitis,
causing pharyngitis pathogenic microorganisms, mainly viruses, occasionally also bacteria. The throat swab test can quickly detect whether the pathogen causing the infection is bacteria or virus. How does this test operate? Let’s take a look at it
① With the help of tongue depressor, the subjects opened their mouth and made a “ah” sound. The palate was lifted up to expose the posterior pharyngeal wall. The swab crossed the root of the tongue and reached the pharyngeal stenosis. Quickly wipe the palatal arch, pharyngeal and tonsillar secretions on both sides.
② Put the swab into the virus transport medium, and break the swab rod with the aid of the cap, and put it completely in the tube.
③ Tighten the pipe cover, mark it and put it into a plastic bag for sealing.
We take bacteria as an example.
If the result of ordinary test is positive, it means that the bacteria have been found and the medicine can be applied directly to the case.
However, if the test is negative, it means that the bacteria need to be cultured, and the bacterial culture takes about 24 hours to 48 hours to have results.
The symptoms of viral infection are bacteria, and the results are negative
But this common detection process is long for patients, and throat swab can quickly determine the pathogen at the first visit, and basically determine the medication plan before the patient leaves the hospital.
This is a convenient, noninvasive and rapid examination.
However, it should be noted that this rapid detection is not 100%.
If there is a problem with the quality of throat swab, false negative is likely to occur.
