What is the difference between a nasal swab and a throat swab

What is the difference between a nasal swab and a throat swab

The accuracy of detecting nasal swabs and throat swabs is usually the same. The main difference lies in the sampling method and sampling site. For nasal swabs, the nasal swab is mainly use to dip the secretions on the surface of the nasal mucosa inside the nasal cavity for detection. In fact, pharyngeal swabs are collect from the oropharynx for testing to determine whether the sampler is infect with the new coronavirus.

Under standardized operations, throat swabs and nasal swabs are two methods for collecting specimens. There is no difference in essence. Both are for collecting specimens from the pharynx. The difference is that one enters from the oral cavity, and the other is from the mouth. Enter the nasal cavity.

For throat swabs, the sampler can see the sample site, but it may cause nausea, vomiting, and other reactions, and because the pharyngeal virus content is affect by diet, drinking, and swallowing actions, it will affect it to a certain extent Throat swab detection rate.

When collecting nasal swab specimens, the swab will enter the nasal cavity. If the operation is standardize, it will cause less irritation to the mucous membrane. However, because the pharynx sampling position cannot be seen, the main reliance is on the sensory resistance of the hand. For those who require more technology, the tools use are more complex. If the operation is improper, it will cause some irritation to the nasal mucosa. Therefore, it is not recommended to do nasal swabs for patients with sinusitis and allergic rhinitis to avoid damage to the nasal cavity.

What should I pay attention to when using nasal swabs?

Pay attention to the use of nasal swabs:

1. Sampling objects should be patients with fever ≥38℃ within 3 days of onset of illness.

2. The volume of the sampling tube should be about 10mL, not too large, so as not to affect the post-processing of the specimen.

3. In fact, the nasopharyngeal swab is best to use a slender swab, about 75mm~80mm in length, which is convenient for sampling.

4. The head of the nasopharyngeal swab should be make as small as possible to avoid discomfort to the patient during sampling

5. Do not use too much solution in the sampling tube, so as not to dilute the sample and affect the post-processing of the sample

6. Therefore, if necessary, two nasal swabs can be used as parallel samples.

7. It is best to store the collected specimens in the refrigerator, and transport them to the laboratory or a place where they can be tested within 24 hours in a refrigerator.

8. If it cannot be sent to the laboratory for testing in time, it needs to be stored at -70°C.

Correct use of Huachenyang nasopharyngeal swab

Correct use of Huachenyang nasopharyngeal swab

Nasopharyngeal swabs are made of special plastic or metal with a long and flexible long handle. The top is make of polyester fiber, rayon and mold nylon.

Sampling of nasopharyngeal swabs is a very common clinical task, which did not appear after the outbreak. Nasopharyngeal swab sampling can be use to assess whether there are respiratory viruses or bacterial infections in adults and children, and is of great significance for the diagnosis of respiratory infections. There are also many influencing factors in the sampling process. If the operation is improper, it will directly affect the inspection results and even lead to misdiagnosis.

Instructions

When sampling a nasopharyngeal swab, the direction of the swab should be parallel to the upper palate, and the tip of the swab should face the direction of the earlobe, not the top of the head. If the swab encounters resistance when passing through the nasal passage, you need to back the swab and try Change the angle and re-enter.

1. The subject’s head is tilted back (approximately 70°) and stays still.

2. Use a swab to estimate the distance between the root of the ear and the nostril.

3. Insert from the nostril straight to the face, and the deepening interval should be at least half the length of the earlobe to the tip of the nose. After encountering resistance, you should reach the nasopharynx, stay for a few seconds to take secretions (generally 15~30s), and rotate the swab 3~5 times.

4. Rotate gently to take out the swab, and put the swab head into the sampling tube containing the virus preservation solution or the cell preservation solution containing RNase inhibitor.

5. Break off the sterile swab rod at the top, discard the tail, screw the cap of the tube tightly and close it with a parafilm.

Precautions:

1. Please do not take antibiotics a few days before the nasal swab.

2. Do not rinse your mouth with disinfectant or smear the local lesion a few hours before the nasal swab.

3. You can’t eat, smoke, or drink a few hours before the nasal swab.

What are the advantages of Huachen Yang nasal swab

What are the advantages of Huachen Yang nasal swab

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 of 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 report in the literature.

2. The patient is well tolerate, and can basically take samples without anesthesia after proficient operation, but the surface anesthesia and contraction of the nasal mucosa can be perform at the beginning.

3. The exposure risk of the sampler is lower than that of an oropharyngeal swab, because we can operate the sampler from behind the patient when sampling, and the patient is required to pull down the mask to expose only the nostrils and cover the oral cavity without directly facing the patient’s oral cavity. , And basically 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 directly in front of the patient, the exposure risk is lower, so the sampler’s heart pressure will not be so great .

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.

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.
