Tips for using oropharyngeal swabs

Tips for using oropharyngeal swabs

The oropharyngeal swab is a sampling tool used to extract mucosal cells and secretions from the oropharynx.

The sampling method requires the use of sterile throat swabs and other items to penetrate deep into the pharynx,

Not only go through the base of the tongue to reach the posterior pharyngeal wall, tonsil recesses, side walls, etc.,

but also wipe left and right 3 to 5 times, and then gently remove the cotton swab.

Then put the swab stained with mucosal cells and secretions into the virus sampling tube and send it for inspection in time.

Instructions

1.Ask the patient to sit down, not only let the patient tilt their head back and open their mouth, but also let the patient make an “Ah~” sound.

2.The sampler can fix the tongue with a tongue depressor, and use an oropharyngeal swab

to cross the root of the tongue to the posterior pharyngeal wall, tonsil recess, side wall, etc.

3.Wipe 3 to 5 times repeatedly to collect mucosal cells.https://www.chenyanglobal.com/

4.Not only must gently remove the cotton swab, but also avoid contact with the tongue, pituitary gland, oral mucosa and saliva.

5.Put the sampling swab and the sample vertically into the virus sampling tube,

Not only do you have to break the swab where it breaks, but also discard the end of the swab.

6.Tighten the cap of the tube,

put it in a biosafety bag, and send it for inspection in time.

Annotation

1.For purulent pharyngitis, the bacterial culture of oropharyngeal swabs is mainly

used for screening group A β-hemolytic streptococcus and hemolytic cryptobacteria.

2.When testing Neisseria gonorrhoeae in oropharyngeal swabs, the clinic needs to inform the laboratory in advance.

3.For pediatric patients, Haemophilus influenzae should  reported routinely.

4.Under normal circumstances, not only cannot the throat swab sample be used alone to diagnose upper respiratory tract infections, but it must also be used in combination with a nasopharyngeal swab

Suction to increase the detection rate of pathogens of respiratory tract infections.

What are the characteristics of flocking swabs

What are the characteristics of flocking swabs

The top of the flocking swab is make of nylon fibers.

The nylon fibers are sequentially attach to the surface of the medical ABS rod through an electrostatic field.

The layers are completely parallel between the layers and perpendicular to the surface of the inner rod for DNA collection.

The principle of flocking swab in DNA collection and precipitation

1.Through the directional friction effect of the swab fiber layer, the cell sample can be completely captured.

2.Since the cell samples are concentrate near the surface of the swab fiber, more than 95% of the sample can be release eventually.

3.The capillary movement between the nylon fibers at the top of the flocking swab forms a powerful hydraulic pressure, which is use to absorb liquid or cell samples.

What are the advantages of flocking swabs for DNA collection?

1.Sample collection process: The unique structure on the top of the swab can greatly increase the number of samples collected.

2.Sample dissolution process: Because the samples collecte by the swab are basically on the surface of the swab, 95% can be release, which means that almost all samples can be wash out.

Why flocking swabs are more beneficial for micro-DNA collection

1.The top of the traditional cotton swab is an internal structure wound with cotton fibers.

When sampling, the fiber clusters are disperse and remain on the fibers, resulting in a decrease in the extraction efficiency of the original low-content DNA, and may even lead to false negative results in the test.

2.The top of the flocking swab has a unique structure, which can almost completely extract and separate trace DNA.

Therefore, the flocking swab has a more obvious advantage in collecting trace DNA.

How to use flocking swabs

1.Open the swab package first, take out the swab carefully, and take care not to touch anything else before sampling to prevent contamination.

2.Place a swab on the place where the sample is needed, and sample by retention, rotation or friction.

3.Gently take out the swab. Generally, put the swab into the virus sampling tube, break it at the point where the swab breaks,

throw away the end of the swab, tighten the cap, and send it for inspection as soon as possible.

Why use a virus sampling tube?

Why use a virus sampling tube?

A virus is a small substance compose of nucleic acid molecules and proteins or only of proteins.
It is small in size and simple in structure.
Since there is no cell structure, the virus itself cannot replicate, so the gene is invad into the host cell, and new viruses are replicate with the help of the latter’s replication system.

After the virus sample is collecte, in order to maintain the viability of the virus sample and prolong the survival time of the virus in the sample, the sampling swab will be store and transport in the preservation solution.

How to use virus preservation solution:

①. Before sampling, note the relevant virus sampling information on the label of the sampling tube;

② According to different sampling requirements, use a sampling swab to sample at the corresponding part;

③. Put the sampled swab vertically into the virus sampling tube;

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.
