Sterile Sampling Swab |Precautions for producing sterile sampling swabs

Disposable sterile sampling medical swab, referred to as sterile swab.

Usually, sterile swabs have a collection material on the stem or at the top of the stem, which can be natural or synthetic. Such as polyester, flocking, etc.

The sterile swab material produced and sold by cell medical (Dongguan) Co., Ltd. is flocking.

The proprietary flocked process optimizes collection and elution, and the breakpoint forming handle can better help break, which is in line with ergonomic design.

Usually, the user holds the stem and wipes the collected material on the surface to collect the sample.

Swabs are sterile to maintain the integrity of the sample.

Usually, there is a resealable sterile container or bag to preserve the integrity during processing and transportation to the laboratory.

Including Covid-19 sampling, sterile workers, food producers and crime scene investigators.

For virus collect samples.

The material, size and shape of the sterile swab head may be different, such as round or pointed.

Some users need to collect products aseptically.

They collect samples from people, animals, even plants and other organisms, while others collect samples from inert surfaces, including furniture such as crime scenes and food processing tables.

Many times, The type of sample required determines the type of sterile swab selected by the user.

Sterile swabs may contain sterile water, which is the only acceptable water for laboratory studies.

Sterile swab manufacturers provide dry and wet swabs.

Usually, they pack sterile swabs in sterile packaging, such as paper, plastic or plastic coated paper covers.

Many manufacturers provide packages that are gamma irradiated and sealed to protect the integrity of swabs.

Some swabs are tubular and may contain liquids such as sterile water, sterile saline, or sodium chloride.

The user should check with the laboratory preparing to process the sample to know what type of swab or solution to use. For many applications, maintaining sample integrity is as important as using sterile swabs.

Many places use sterile swabs to monitor the environment or work area, control infection and its transmission, and monitor health management plans.

These include hospitals and medical institutions, food and drug processing facilities, and animal care facilities, such as veterinary clinics and zoos.

Materials for nasopharyngeal sampling swabs – manufacture

During the sampling process of the COVID-19, the pharyngeal swab is in direct contact with the sampling site, and the material of the sampling head is closely related to the subsequent detection.

The sampling swab head: made of flocked swab or artificial fiber.

Prohibited :calcium alginate sponge swab (including bamboo swab) .

Cotton products can not be used for the head of the swab, because the cotton fiber has strong adsorption on protein and is not easy to elute into the subsequent preservation solution;

The broken wooden stick or bamboo stick containing calcium alginate and wooden components will also adsorb protein and even inhibit the subsequent PCR reaction.

Recommended:PE fiber, polyester fiber, polypropylene fiber and other synthetic fibers  as the materials for manufacturing the swab head.

It is not recommended to use natural fibers such as cotton or nylon fibers, because nylon fibers (similar to toothbrush heads) have poor water absorption, which will lead to insufficient sampling and affect the initial inspection rate.

Pharyngeal swab material: prohibited! calcium alginate sponge.

Viral Transport Medium Tube

Whether nucleic acid detection or virus detection, Viral Transport Medium Tube and Sampling Swab play a great role.

Sampling swab is used to collect virus samples, while virus preservation solution plays the role of preserving these virus samples.

Which not only ensures the integrity of nucleic acid virus, but also facilitates the later detection accuracy.

How many virus preservation solutions are there? What are the functions and differences?

At present, there are two kinds of virus preservation solutions on the market, namely inactivated virus preservation solution and non inactivated Viral Transport Medium.

Non-inactivated  Viral Transport Medium can protect the protein and nucleic acid of the virus.

Inactivated Viral Transport Medium usually contains the cleavage salt of inactivated virus to cleave the protein and protect the nucleic acid.

Specific uses of virus sampling tube:

1. The virus sampling tube is generally used for nucleic acid extraction and later virus isolation of influenza virus, hand, foot and mouth virus and rubella virus in clinical patients. The amount of liquid required is usually 35m or 5m. (with nucleic acid detection kit and spore culture medium)

2. For the collection and short-term transportation of avian influenza virus in the external environment. The amount of liquid required is usually 6ml.

3.  For daily monitoring and sampling of poultry, pigs and other animals. The amount of liquid required is usually 15m.

4. For short-term preservation of virus samples. (2-8 ℃ for 48 hours) for necessary cell culture.

5. Used for long-term preservation of virus samples (- 70 ℃ – 196 ℃ for one year) for necessary cell culture.

6. To collect clinical respiratory virus rapid detection kit.

7. To collect clinical samples of mycoplasma, chlamydia and Ureaplasma.

8. To transport tissue samples from the sampling site to the detection laboratory for necessary cell culture.

COVID-19 Swab Test |One Minute to Learn about Nucleic Acid Test

So far, the number of confirmed cases of the global epidemic has exceeded 237 million, followed by the recurrence of the epidemic. We must do a good job in COVID-19 testing and strive to defeat the virus at an early date.

1. Why a nucleic acid test? What does it test for?

Nucleic acid swab detection is the direct evidence to find the existence of virus. The novel coronavirus pneumonia virus nucleic acid test positive, indicating that the presence of virus in the subjects, may be infectious.

If the patient has fever, respiratory symptoms or other clinical features of NCP, the patient can be diagnosed as NCP when combined with positive nucleic acid test; if there are no clinical symptoms, the nucleic acid test result is positive, can be judged as asymptomatic infection.

Novel coronavirus pneumonia is a diagnostic standard for new crown pneumonia.

2. Nasopharyngeal swab test and oropharyngeal swab test, which test method is better?

As we all know, nucleic acid detection generally adopts pharyngeal swab detection. Pharyngeal swab testing includes nasopharyngeal swab testing and oropharyngeal swab testing. The difference between the two lies in the different sampling positions, but there is no essential difference. Most medical institutions use oropharyngeal swab detection, because this detection method has less discomfort and is more convenient for sample collection.

3 .what are the precautions before and after COVID-19 Swab Test?

Before testing;

Get your ID card ready before you go out!

Wear masks correctly without fasting;

Try to avoid eating in the first 2 hours to avoid vomiting and other discomfort;

Try not to drink water, drink, smoke, drink or chew gum in the first 30 minutes;

When sampling, reduce swallowing action, swallow less saliva and don’t clear throat;

We should inform the testing personnel in advance whether they have a history of nasal surgery, bending of nasal septum, blood diseases, throat diseases or taking anticoagulants;

Before testing, remove the mask after the medical personnel give a signal, wear it immediately after sampling, and prepare a spare mask for easy replacement at any time after pollution.

Testing;

Consciously queue up and keep a distance of more than one meter;

When collecting oropharyngeal swabs, tilt your head back, relax as much as possible, breathe deeply, and open your mouth to make an “ah” sound, which is helpful to complete the sampling quickly;

The nose may be itchy during the collection of nasopharyngeal swabs. If you sneeze, cover your mouth and nose with paper towels or elbows immediately;

During the detection, try not to touch the detection platform and other articles, and do not touch the protective clothing of the collection personnel.

After detection

Leave the site immediately after sampling, and do not spit or throw garbage at the collection point and surrounding areas;

The inspectors shall pay attention to hand hygiene before and after the test. They can wipe their hands with hands-free disinfectant, hands-free alcohol, disinfection cotton, etc.

4 How can nucleic acid detection alleviate the discomfort of sampling?

Nasopharynx swab sampling and oropharyngeal swab sampling will make the sampled person feel slightly uncomfortable, which can be relieved after a short rest. Therefore, during the sampling process, the sampled person shall cooperate with the sampling personnel as much as possible, relax as much as possible, and do not over move the head to avoid scratching the mucosa with the sampling swab.

Mouth Swab VS Nasal Swab

Mouth Swab VS Nasal Swab

Mouth Swab VS Nasal Swab

Recently, COVID-19 is prevalent worldwide.

It is one of the most serious public health problems in the world.

The diagnosis of COVID-19 requires the combination of epidemiological history, clinical manifestations and laboratory examination, especially the examination of pathogenic pathogens.

It is an important basis for the diagnosis of New Coronavirus disease.

The diagnosis of COVID-19 needs to be checked by nucleic acid. If we can detect the virus, we can diagnose the disease.

The new crown vaccine is mainly used for the examination of the secretion. The most common method is to check the nasal swabs and mouth swabs.

The secretion of nasopharynx is used for nucleic acid detection. If there are positive findings, we can diagnose the disease.

There are certain differences between Mouth Swab VS Nasal Swab.

First, there are certain differences in the methods and parts adopted. Nasal swabs generally enter from the nasal cavity and take the secretions at the back of the nasopharynx, while pharyngeal swabs enter from the mouth to the throat and take local secretions for inspection, that is, the two enter in different ways.

Secondly, there are certain differences in the impact of nasal swabs and pharyngeal swabs on patients. Relatively speaking, nasal swabs are not easy to be accepted by patients. After entering the nasal cavity, they often need to enter a certain depth before they can effectively take samples. For patients, it may cause local discomfort. Pharyngeal swabs enter from the mouth and take secretions from the throat, It may also cause irritation such as nausea.

In addition, the positive rate of samples taken from pharyngeal swabs and nasal swabs is generally not much different, but for pharyngeal swabs, there may be some differences due to the influence of some oral factors.

However, at present, pharyngeal swabs are more widely used in clinic, and even some samples need to be collected together with pharyngeal swabs and nasal swabs, There is a certain possibility to improve the positive rate.

Oral Swab Stick

Oral Swab Stick

Oral Swab Stick-Oropharyngeal sampling swab.

COVID-19 Oral Swab test is an important reference for diagnosis and evaluation of curative effect of new crown pneumonia.

Nucleic acid screening samples mainly come from deep cough sputum or pharyngeal swabs.

Pharyngeal swabs include nasopharyngeal swabs and oropharyngeal swabs.

The results of COVID-19 nucleic acid test are also useful.

What is the key to the collection of nucleic acid test specimens from pharyngeal swabs?

Whether collecting nasopharyngeal swabs or oropharyngeal swabs, the collection depth is the key.

For example, if the nasopharyngeal swabs are not collected deep in the nasal cavity, most of the cells that may be collected are virus-free cells, which may cause “false negative”.

What is the difference between Oral Swab Stick and Nasal Swab?

Pharyngeal division includes nasopharynx, oropharynx and laryngopharynx. The mucosa of the three is continuous and belongs to the area of upper respiratory tract. The sampling path of nasopharyngeal swab and oropharyngeal swab is different. Oral sampling is oropharyngeal swab and nasal sampling is nasopharyngeal swab.

What are the advantages of nasopharyngeal swabs?

It can stay in the pharynx for a long time in order to obtain more sufficient specimens; The exposure risk of the sampler is lower than that of the oropharyngeal swab, because the sampler can stand behind the patient’s side during sampling, and the patient is required to pull down the mask to expose only the nostrils and cover the mouth without looking directly at the patient’s mouth, and there is basically no pharyngeal reflex. A few patients may have sneezing reflex after sampling, and the patient can be covered with elbows or paper towels, And because the sampler is not directly in front of the patient, the exposure risk is quite low, so the psychological pressure of the sampler will not be so great.

Can a positive oral swab stick confirm COVID-19?

The novel coronavirus novel coronavirus infection can be diagnosed by the new swab positive guide for new coronavirus infection, but it does not necessarily indicate pneumonia.

After infection with COVID-19, the old person may show two different infections, including fever, dry cough, weakness, and asymptomatic infection.

Patients with positive nucleic acid test of new crown must be isolated and treated.

Only when nucleic acid is negative for more than 24 hours, body temperature is normal and pneumonia symptoms disappear can isolation be lifted according to the situation.

How to sample oropharyngeal swabs?

First collect the oropharynx, gently and repeatedly wipe it for more than 3 times, and then collect the depth of the throat wall for more than 3 times.

The whole process takes about a few seconds. It may be a little disgusting, but there won’t be too many reactions. It’s more acceptable.

According to the personal experience of colleagues: slightly disgusting, but completely acceptable

The site experienced the collection of oropharyngeal swabs. The whole sampling process is only a few seconds and there is almost no discomfort.

How to Obtain a Nasopharyngeal Swab Specimen

As a non-invasive operation, nasopharyngeal swab sampling is the first choice for diagnosis, monitoring and differential diagnosis of New Coronavirus pneumonia. Its sampling randomness is high. However, the sampling personnel may have false-negative test results due to the different location, strength and time of scraping samples, which may have an adverse impact on the epidemic prevention and control. During the operation, the patient choked and splashed to produce an aerosol, which is very easy for medical staff to have occupational exposure.

This paper mainly explains in detail the protection of medical staff when collecting nasopharyngeal swabs, the collection, packaging and transportation of nasopharyngeal swabs, as well as the patient’s body position, operation methods, collection parts and precautions during specimen collection.

Effective communication and nurse-patient cooperation help the successful collection of nasopharyngeal swabs.

Before the operation, the degree of cooperation of patients should be effectively evaluated. Inform the patient of the collection purpose and precautions in advance.

Clinicians should be cautious if the patient has recent nasal trauma or surgery, a significant deviation of the nasal septum, or a history of chronic obstructive nasal patency or severe coagulation disease.

Standard protection is the foundation of successful nasopharyngeal swab collection

Operator preparation: first, wear protective clothing, wash hands with soap and water (or alcohol), and wear a pair of non-sterile gloves. Then, according to the recommendations of the Centers for Disease Control and prevention, wear an N95 or higher protective mask. Finally, wear a face mask to protect your face and eyes.

Swab Nasal Covid Sampling preparation: operating platform; Sampling materials, including nasopharyngeal test swab, VTM kits, inspection sheet and bar code, transport bag and hand disinfectant, to ensure the sterilization effect and validity period.

Nasal swab specimen collection method.

(1) Wet the flocked swab in normal saline.

(2) Measure the distance from nostril to ear root with a swab and mark with your fingers.

(3) Insert the swab into the nostril in the direction perpendicular to the nose (face) until the finger touches the nose, keep the swab in the nose for 15-30 seconds, and then rotate it gently for 3 times.

(4) Put the swab into the virus delivery medium, break the swab rod and place it completely in the tube.

(5) Tighten the tube cover, mark it, put it into the specimen bag and seal it.

(6) If it is necessary to collect from two nostrils, one swab should be used respectively.

(7) Store at 4 C or on ice (short term storage).

CDC recommends that all patients suspected of infection with COVID-19 use masks.

Ask the patient to take off the mask and wipe the nose with a paper towel to remove excessive secretions from the nasal cavity.

Remove the cotton swab from the package. Tilt the patient’s head back slightly so that the nasal tract is more accessible.

Let the patient close his eyes to reduce the slight discomfort caused by the operation.

Gently insert the swab into the nasopharynx along the nasal septum until resistance is felt.

Tips for nasopharyngeal swab sample collection.

The nasopharynx swab is inserted quickly. Do not hesitate. Some patients are intolerant to the operation of probing the nasopharyngeal swab into the nasal cavity, resulting in tears, foreign body feeling, etc. before the operation, ask the patients to inhale deeply in order to avoid choking and coughing.

When the cotton swab reaches the expected depth, do not continue to go deep, so as not to cause nasal mucosal damage and bleeding. During the stay, use finger strokes with the patient to read the seconds. It can distract attention, eliminate tension and motivate patients to ensure successful collection.

Never allow the patient to fully raise his head and bend the swab, which will lead to incorrect retention position of nasopharyngeal swab head and ultimately affect the accuracy of specimen collection results.

The operator can select the left / right side of the operator according to his left and right hands, and stand on the patient’s head and shoulder for operation. The patient’s head does not need to be biased to the opposite side. It is difficult to control the entry angle of the flocked swab when facing the side head, which may cause mucosal irritation. For patients with excessive tension, the operator can hold the patient’s hand and give comfort.

viral transport medium with swab | COVID-19 sampling and collection kits

The epidemic has disrupted the whole world and affected many industries.

During the outbreak of  COVID-19, people were paying close attention to the epidemic situation while doing personal protection. Novel coronavirus pneumonia and influenza were the most frequent period of communication in winter and spring. The most important way to control the epidemic is to select new patients with new crown pneumonia from many respiratory patients.

About viral transport medium with swab.

Swabs and virus transport media are a transport and collection system for long-term freezing, transport and collection of clinical specimens containing viruses.

The main species of organisms usually transported through this medium include chlamydia, urea plasma organisms and mycoplasma.

With the outbreak of COVID-19 pandemic, swabs and virus transport mediums were used to freeze and collect SARS-CoV-19 virus samples.

Rub a swab on the skin or vesicles to collect virus samples. The collected samples are then sent to the laboratory with transport media.

Why do swabs need virus transport media？

After virus collection, the traditional method can not be detected by PCR immediately. The virus itself will quickly dissolve in vitro and affect subsequent tests.

viral transport medium with swab -vtm kits
