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.

Introduction and characteristics of sterile swabs

Introduction and characteristics of sterile swabs

Sterile swabs, full-name disposable sterile sampling swabs, not only for bacteriological sample processing, COVID-19, nasal swab sampling, throat swab sampling, oral swab sampling, but also for virus cell culture , DFA detection, rapid direct detection, enzyme immunoassay, polymerase chain reaction based on molecular diagnostic tests and forensic identification are ideal choices.It can also be use for throat sampling of respiratory viruses such as influenza, swine flu, avian flu, hand, foot and mouth.

Scope of application

The best tool for skin surface sampling, DNA collection, oral cells, physical surfaces, microorganisms, bacteria and viruses testing and sampling. The disposable aseptic sampling swab CY-98000, with a break point of 3cm, is superior in that it is better than traditional swabs, The collection and release volumes are large and can be broken. The traditional swabs need to be cut by the laboratory staff with scissors, which is too troublesome and too time-consuming. Our new flocking disposable sampling swab greatly reduces the time cost.

Features

  1. It not only has excellent water absorption capacity, but also can increase the number of specimens collected on the watch from 20% of the traditional sampling swab to 60%.
  2. The release rate of the collecte specimens exceeds 90%, thus ensuring the high reliability of the results.
  3. Different preservation solutions are selecte for different types of specimens.
  4. The unique easy-to-break design on the plastic rod is not only convenient for transporting specimens, but also particularly suitable for preservation
  5. We not only use ethylene oxide for sterilization, but also for irradiation sterilization, but also individually packaged.

DNA aseptic flocking swabs are suitable for humans and animals, and have advantages over other DNA test samples in design. Its unique test sample matrix and rapid release interface are more conducive to efficient cell collection and maximize DNA yield. The test piece has been sterilize with ethylene oxide and passed the test for human DNA contamination.

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.
