How to use a sterile swab

How to use a sterile swab

Sterile swabs, the full name of single-use sterile sampling swabs, are used in bacteriological sample processing, COVID-19, nasal swab sampling, throat swab sampling, oral swab sampling, virological cell culture, DFA testing, Rapid and direct testing, enzyme immunoassay testing, polymerase chain reaction and molecular diagnostic-based testing, as well as forensic identification are ideal. It can also be used for throat sampling of respiratory viruses such as influenza, swine influenza, avian influenza, hand, foot and mouth.

The sterile flocking swab is suitable for humans and animals. It has advantages over other DNA test samples in design. Its unique test sample matrix and quick release interface are more conducive to efficient cell collection and maximize DNA yield. The test piece has been sterilized with ethylene oxide and passed the test for human DNA contamination.

Sterile swabs are suitable for skin surface sampling, such as DNA collection, oral cells, surface, microorganisms, bacterial and virus detection sampling, etc. The advantage is that it is easier to use than traditional swabs. The collection and release volume is large, and it can be broken. Traditional swabs The lab staff also need to use scissors to cut it, which is too troublesome and too time-consuming. Our new flocking one-time sampling swab greatly reduces the time cost.

Instructions

Pharyngeal swab sampling

1. Open the swab package first, take out the swab carefully, and be careful not to touch anything before sampling to avoid contamination.

2. The sampler can first use the tongue depressor to remind the patient to make an “ah~” sound.

3. Raise the patient’s palate to expose the posterior pharyngeal wall. Pass the swab across the base of the tongue to the back of the pharynx (lesions) and quickly wipe the palatal arch, pharynx and tonsil secretions on both sides (15-30 seconds).

4. Put the sampled swab into the virus sampling tube, and break the swab rod at the mouth of the tube cover to completely place it in the tube.

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

6. Submit the specimens for inspection in time.

Nasal swab sampling

1. Open the swab package first, take out the swab carefully, and be careful not to touch anything before sampling to avoid contamination.

2. Ask the patient to keep his head still and remove the secretions on the surface of the anterior nasal cavity (it is best to let the patient blow his nose first).

3. The sampler can stand on the side of the patient, reducing the chance of infection caused by coughing and sneezing, and at the same time alleviating the pressure of the sampler.

4. Measure the distance from the nostril to the root of the ear with a swab and use the hand as a mark.

5. Slowly insert the nasal swab into the nostril (toward the earlobe), with a feeling of touching the wall, let the swab stay in the nose for 15-30 seconds, and then gently rotate it 3 to 5 times.

6. Take out the swab slowly and put it vertically into the virus sampling tube.

7. At the breaking point, break off the swab, discard the tail, and place the swab completely in the tube.

8. Tighten the cap of the tube, make a mark, and put it in a biosafety bag and seal it.

9. Submit the specimens for inspection in time.

The scope of application of flocking swabs

The scope of application of flocking swabs

Flocking swabs have a wide range of uses, and are very useful in bacteriological sample processing, virological cell culture, DFA testing, rapid and direct testing, enzyme immunoassay testing, polymerase chain reaction and molecular diagnostic-based testing, as well as forensic identification. ideal. It can also for throat sampling of respiratory viruses such as influenza, swine flu, avian flu, hand, foot and mouth.

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 captur.

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

3.The capillary movement between the nylon fibers on the top of the flocking swab generates a powerful hydraulic pressure 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: The sample collect by the swab is basically located on the surface of the swab. Therefore 95% of the sample can be releas, which can be regard as almost all samples can be wash off.

Why flocking swabs are more beneficial for micro-DNA collection

1.The top of the traditional cotton swab is make of cotton fiber entangl internal structure. When sampling, the fiber clusters will be scatter and retain on the fibers. As a result, the precipitation efficiency of the original low-content DNA is reduc.

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.

What are the uses of disposable sampling swabs you should know

Disposable sampling swabs, also called single-use sampling swabs, are the most commonly used detection tools for nucleic acid testing. They are use to collect oral mucosal cells,

oral microorganisms, surface microorganisms, surface bacteria, virus sampling and transportation, and DNA , RNA collection, throat sampling, cervical sampling, nasopharyngeal sampling.

Paternity test DNA collection, transportation and storage, virus microbes, influenza sample collection, storage, transportation and extraction solutions.

Use of disposable sampling swabs

Disposable sampling swabs are suitable for the collection of microorganisms, which can assist hospitals or laboratories to detect viruses or research virus sampling,

and are use for biological samples from the natural cavities of humans or animals, such as throat, nasal cavity, oral cavity, vagina, etc.

It can also be use for human oral or nasal disease detection.

A sampling swab is needed to collect oral epidermal cells or nasal virus samples, and the cells or samples are store in the collection tube, and then transferre to the laboratory for testing.

Features of disposable sampling swabs

The disposable sampling swab adopts the flocking method of spray and electrostatic charge,

so that millions of nylon microfibers are vertically and evenly attach to the end of the handle.

The capillary action between the nylon fiber bundles is conducive to the strong hydraulic absorption of liquid samples.

Compare with traditional twiste fiber swabs, most of the samples collecte by traditional twisted swabs are trappe in the fiber matrix at the end of the swab,

and only a small amount of 20-30% of the collect samples can be releas, while flocking swabs can remove microorganisms.

The sample remains on the surface of the fiber, and the rapid elution is greater than 95% of the original sample,

which easily improves the sensitivity of detection.

Sampling swabs are certify to be free of ribonuclease (RNAse), deoxynucleic acid (DNAse) and human deoxyribonucleic acid,

and no PCR inhibitors.

1.It is make of non-inhibitory DNA amplification materials, which has been verifi by direct PCR amplification,

eliminating the need for extraction steps.

2.It adopts single and independent packaging to avoid pollution.

3.Strict process conditions, no DNase and amplifiable human DNA.

4.The tube body is transparent, and the inspection materials are intuitively visible.

5.The unique casing design ensures the air circulation in the casing, prevents the sample material from being mildew due to the damp and seal environment,

and at the same time avoids the contamination of impurities in the outside air,which will affect the quality of the inspection.

Introduction and function of throat swab

Introduction and function of throat swab

Throat swab is a swab used to check whether the throat is diseased and for throat sampling. It can be said to be a detection method to understand the patient’s condition,

oral mucosa and pharynx infection. Because the pharynx is more susceptible to disease caused by infection caused by external bacteria when the body’s body or local resistance is reduced,

so when we seek medical treatment,

doctors need to collect some cells or viruses for observation to understand the patient’s disease Happening.

In appearance, our throat swab should be straight, neat, smooth, uniform in color,

free of burrs, mildew, scars, scratches, cracks and other defects. As a qualified swab, it should be very good.

Clean, odorless, and soft to the touch, without maculas, stains, or foreign objects.

In terms of performance, the swab should be able to withstand 4N static pressure perpendicular to the axial direction for 15 seconds without permanent deformation or breaking.

The breaking force of the depression at the sampling tip should be no less than 2N.

When using a throat swab, be aware that the flocking has a very light tingling sensation on the skin,

so before use, people who are allergic to flocking should first place the swab

on the sampling part and gently perform an allergy test Later,

it is used for sampling.

Throat swabs are generally used to check for what disease

Throat swabs are generally use to check for what disease

If we are sick, it is very important to seek medical treatment in time. When we arrive at the hospital, in addition to listening to our description of the medical history, the doctor also needs to perform corresponding examinations. Only through medical history consultation and laboratory examinations can we diagnose the disease and its medication plan.

When we go to the hospital for physical examination, the items include blood test, urine test, stool test, etc. What we are going to mention today is a test call throat swab culture. I believe that this kind of test is familiar to everyone this year, and everyone should have been expose to it. So what kind of disease do throat swabs usually check? Next, I will give you a specific description of this issue.

Throat swab inspection is to take secretions from the throat, conduct bacterial culture, and then conduct a drug susceptibility test based on the infected bacteria. The results of the throat swab examination can provide an important basis for the accurate medication of the clinician.

Throat swabs are generally used to check upper respiratory diseases, such as acute suppurative tonsillitis, acute pharyngitis, diphtheria and other respiratory diseases.

After taking out the secretions and performing corresponding examinations,

it can be known which bacteria are the main infections of the patient. Finally, the doctor will use the susceptibility results of the cultur bacteria as an important basis for clinical medication.

Note that when undergoing a throat swab examination, there may be mild neural reflexes, so everyone must hold back.

What to pay attention to when sampling nasal swabs

What to pay attention to when sampling nasal swabs

The following are the things we need to pay attention to when we go for a nasal swab.

Precautions for samplers:

1. The sampler stands on the side of the subject and takes the sample.

2.Subjects were asked to pull down the mask to reveal only their nostrils.

If the subject has a sneezing reflex, the subject can block it with an elbow or a tissue. This will not be directly in front of the subject and can reduce the risk of exposure.

3. If the subjects turbinate hypertrophy, nasal passages are narrow, and the nasal swab insertion feels resistance, you can try to change one side of the nasal cavity or directly change to oropharyngeal swab collection.

4. People with nasal allergies may easily induce sneezing. It is recommended to use an oropharyngeal swab for sampling.

5. Remember to wear a protective mask/face screen. For individuals who are highly suspecte or basically diagnos, or have severe coughs and hiccups, they should wear protective clothing.

6. After sampling, it is necessary to change gloves, perform hand hygiene and disinfection, and spray disinfectant on the contact area.

Precautions for the subject to do nasal swabs:

1. Do not take antibiotics for a few days before using the nasal swab. This will affect the test results.

2. In the few hours before the nasal swab is wipe, do not use disinfectant mouthwash or apply the topical area.

3. You cannot eat, smoke or drink for several hours before the nasal swab is wipe.
