Use skills and introduction of virus sampling tube

Use skills and introduction of virus sampling tube:

Virus sampling tube-suitable for collecting and transporting new coronavirus, influenza virus, avian influenza (such as H7N9), hand, foot and mouth virus, measles and other virus specimens, as well as mycoplasma, ureaplasma and chlamydia specimens.

② The virus sampling tube must be transporte within 48 hours under refrigeration (2-8°C).

Long-term storage of viruses and relate samples in -80°C or liquid nitrogen environment.

Sampling method for collecting virus through virus sampling tube:

①. Measure the distance from the tip of the nose to the earlobe with a cotton swab and mark it with your fingers.

②. Insert the sampling cotton swab into the nasal cavity in the direction perpendicular to the nose (face).

③ The distance between the swab should be at least half the length of the earlobe to the tip of the nose.

④. Leave it in the nose for 15-30 seconds, gently rotate it 3-5 times, and then take out the swab.

It is not difficult to see from the method of use that sampling is a technical task,

which is difficult and easy to contaminate.

The quality of all collected samples is directly related to subsequent testing.

Requirements for sampling swabs:

If the viral load of the collected sample is low, it is easy to cause false negatives and difficult to diagnose.

Some sampling swabs have low viral load, improper break points, and the operator is not easy to break.

This not only limits the sampling efficiency, but also It is easy to cause false negatives in nucleic acid testing.

Therefore, the sampling cotton swab head should use synthetic fiber flocking instead of cotton or calcium alginate sponge;

the material of the cotton swab handle is recommend to use hollow polystyrene (PS) extrusion tube or polypropylene (PP) injection molding indentation tube instead of using Wooden sticks or bamboo sticks.

Why can’t we use wooden sticks or bamboo sticks as swab sticks?

Because wooden sticks or bamboo sticks containing calcium alginate are broken and place in the preservation solution, they will absorb protein and even interfere with subsequent tests.

Contraindications of sampling swabs:

① Cotton fiber has strong adsorption power to protein and is not easy to wash.

② The length of the swab should not be too short, and the breaking position should not be too close to the head of the swab,

so as not to contaminate the patient’s body fluids during the operation;

③ The location of the breakpoint should be reasonable,

and the sampling pipe should be broken to avoid contamination caused by the overflowing liquid in the pipe.

④ The virus protection function of the virus sampling tube can keep the virus activity in a lower temperature range.

⑤ Reduce the speed of virus decomposition and increase the positive rate of virus isolation.

What is a throat swab

What is a throat swab
A throat swab is a swab used to check whether the throat is diseased and to sample the throat. It can be say to be a detection method to understand the patient’s condition, oral mucosa, and pharynx infection.

Because the pharynx is affected by infections caused by external bacteria when the body’s body or local resistance is reduced,

the doctor needs to collect some cells or viruses for observation when we seek medical treatment, so as to understand the patient’s disease. Illness.

How are throat swabs collected?

When sampling a throat swab:

  1. First, check personal information with the subject.
  2. Then tear off the outer packaging of the sampling swab and take out the sampling swab.
  3. Let the subject open his mouth to make an ah sound, exposing the throat, and if necessary, press the tongue down with a tongue depressor (lightly press the front 2/3 of the tongue and the back 1/3).
  4. Take out the sterile swab, gently and quickly wipe the bilateral pharyngeal tonsils and the back wall of the pharynx 3 times, and put the swab head into the preservation solution.
  5. At the mouth of the preservation tube, fold off the tail of the swab firmly, discard the tail, tighten and cover the tube cap (strictly perform aseptic operation).
  6. Check the patient’s name again after sampling.
  7. Put it into a sealed bag and a special transfer box, and quickly send the sample to the laboratory for inspection.

The advantages of throat swab products:

  1. The collected samples have a release rate of more than 90%.
  2. It can be operated with one hand to avoid pollution and is convenient to use.
  3. Ethylene oxide sterilization, independent packaging.
  4. Unique craftsmanship increases the comfort of the collected person.
  5. Under normal temperature conditions, samples can be store for 12 months.
  6. Pharyngeal Swab The swab set is a combination of swab and preservation solution,
  7. which cooperates with one time/person to collect swab samples.

Advantages and collection methods of nasal swabs

Advantages and collection methods of nasal swabs

Advantages of nasal swabs:

1.The nasal swab adopts the spray-type implanted nylon fiber technology, which is first-class in the domestic and foreign markets.

This material can absorb more samples, effectively increasing the collection and release rate of cell and virus samples, and The sample is easier to fall off, so that the final analysis result can be more accurate.

2.The nasal swab adopts a medical ABS plastic rod with a breakable design to facilitate the transportation of specimens.

3.Excellent quality can double the collection effect of swabs, from the 20% sampling and release rate of traditional swabs to the current 95% collection and release rate,

thus ensuring high results reliability.

4.Ethylene oxide sterilization, independent packaging, equipped with virus sampling tube,

convenient transportation of culture medium, and storage at room temperature.

Advantages in nasal swab sampling:

1.It can stay in the pharynx for a longer period of time in order to obtain more sufficient samples.

This is also the reason why the positive rate is higher than that of oropharyngeal swabs reported in the literature.

2.The patient is well tolerated, and can basically take samples without anesthesia after proficient operation,

but the surface anesthesia and contraction of the nasal mucosa can be performed at the beginning.

3.The exposure risk of the sampler is lower than that of the oropharyngeal swab, because when sampling,

we can stand behind the patient and ask the patient to pull down the mask to expose only the nostrils and cover the oral cavity without directly facing the patient’s oral cavity.

And almost no pharyngeal reflex, a few patients may have sneeze reflex after sampling, the patient can be covered by elbow or tissue,

and because the sampler is not in front of the patient, the risk of exposure is lower, so the sampler’s heart pressure will not be so great .

Advantages and collection methods of nasal swabs

Nasal swab collection method:

1.Please keep the patient’s head still and remove the secretions on the surface of the anterior nasal cavity.

2.Use a swab or other tool to measure the distance from the nostril to the base of the ear and mark it with your finger.

3.Gently and slowly insert the swab through the nasal cavity.

4.Swab to the finger mark or stay for a few seconds after encountering resistance to absorb secretions

(usually stay for 15-30 seconds, then gently rotate 3 times).

5.Rotate gently to take out the swab and place it in the virus sampling tube (in the transfer medium);break off the tail rod of the swab along the breaking point to completely place it in the tube. Tighten the cap of the tube.

6.If you need to collect from two nostrils, another swab should be used.

7.Note the information of the person being collected and send it to the inspection room for inspection as soon as possible.

What conditions must a good virus sampling tube meet?

What conditions must a good virus sampling tube meet?

The virus sampling tube is used for the collection, storage and transportation of new coronavirus,

influenza virus, avian influenza (H7N9, etc.),

measles and other virus specimens, mycoplasma and chlamydia specimens.

Why choose a professional and excellent virus sampling tube?

Because the quality of the collected samples is directly related to the follow-up inspections,

if you use bad sampling swabs and virus preservation solutions,

the collected samples will not contain high levels of virus.

As the small living environment changes, the phases will decompose,

which is easy Affect the test results, it is difficult to confirm the diagnosis or easy to be misdiagnosed.

Therefore, by using a professional virus sampling tube, the effectiveness of the sample can be guaranteed,

and false negative and misdiagnosis of the virus can be reduced!

What conditions must a good virus sampling tube meet?


The biggest feature of an excellent virus sampling tube is that

Whether it’s the number of samples collected or the number of viruses released,

Are much higher than ordinary virus sampling tubes,

and it ensures the activity and integrity of virus particles, providing the primary guarantee for subsequent virus isolation and nucleic acid detection .

(1) Sample validity:

The non-inactivated virus preservation solution must maintain the activity of the pathogenic infectious agent,

and it is best to maintain the activity of the virus at room temperature. Meet the time from sample sampling to laboratory testing.

It is necessary to limit and prevent the reproduction of symbiotic microorganisms to ensure the reliability of diagnostic tests

The inactivated virus preservation solution needs to inactivate the virus but maintain the nucleic acid of the virus.

(2) In terms of safety:

Because the virus sampling tubes are basically all infectious materials, and some are highly pathogenic infectious materials,

the requirements for packaging containers are very strict, and they need to meet safety and ensure that the liquid does not leak during transportation.

How to Collect a Nasopharyngeal Swab for Testing

Choose Huachenyang’s professional CY-96000 nasopharyngeal swab with individual packaging. Wash your hands and wear sterile gloves before you grab the stick. Have the patient’s head backward nearly 70 degrees. Then the nasal swab would go down horizontally to the posterior nasopharynx.
Insert the tip into one of the nostrils slowly. Take care not to hurt the vulnerable nasal wall. Undoubtedly, it would be a little uncomfortable but not painful. Actually, the fine flocking tip would help to make it easier.
When reaching to the postal nasopharynx, rotate the stick 2-3 times to make the flocking tip absorb enough target sample.
Remove the swab out slowly and place it into the sterile VTM tube as soon as possible. Break the plastic handle according to the breakpoint before you screw the cap.
