Respiratory Swab Collection

1. Importance of Flocked Nasopharyngeal Swabs in Pertussis Detection

Early diagnosis of pertussis relies heavily on respiratory specimen collection and testing, with flocked nasal swabs playing an indispensable role in the sampling process.

1.1 Precise Sampling Ensures Accurate Detection

Bordetella pertussis colonizes the ciliated epithelial cells of the respiratory tract, making the collection of nasopharyngeal secretions essential for obtaining reliable samples.

Nasopharyngeal sampling sticks, made with specialized materials, feature a flocked design that significantly improves secretion collection, especially those containing Bordetella pertussis.

Compared to traditional throat swabs, nasopharyngeal collection tools conform better to the nasopharyngeal region, achieving higher positive isolation rates and improving sample quality. This reduces detection errors and provides stable results for subsequent PCR testing or bacterial culture.

1.2 Compatible with Multiple Detection Methods

Collected samples can be used for various detection techniques, including:

  • PCR Testing: Fast and sensitive, providing results within hours and suitable for early-stage diagnosis.
  • Bacterial Culture: Though time-consuming, it offers detailed analysis of bacterial characteristics, aiding further treatment.

The combination of these methods enables a comprehensive assessment of pertussis progression, laying a foundation for precise treatment.

Flocked Swabs For Sample Collection

Flocked swabs have spray-on nylon flocked fibre technology allowing for improved collection and release of the patient samples.

2. Design Advantages of Flocked Nasopharyngeal Swabs

2.1 Efficient Sample Collection and Release

The core advantage of nasal cavity swabs lies in their unique flocked structure, which ensures secure adhesion of secretions upon contact with the nasopharyngeal area. During laboratory testing, these swabs easily release the collected samples, preserving sample integrity and minimizing loss.

2.2 Soft and Comfortable Design

Since the sampling site is sensitive, swabs must balance efficiency and comfort.

Deep nasal swabs use flexible materials and a soft, slender design, reducing discomfort during sampling. This makes them particularly suitable for sensitive groups, such as infants.

2.3 Safe and Hygienic Packaging

To ensure hygiene and safety, flocked nasopharyngeal swabs are typically packaged in individually sealed paper-plastic bags or tube transport containers. These designs effectively prevent external contamination. Additionally, irradiation sterilization minimizes infection risks, ensuring sterile sampling.

3. Broad Applications of Flocked Nasal swabs

Flocked swabs for sample collection

The flocked swab deposits nylon fibers on the surface of the medical ABS rod in order in a certain direction through the electrostatic field to form a brush layer. The layers are fully parallel and perpendicular to the surface of the internal rod.

The brush head can be used for Virus cell collection.

It can be used for sampling the natural cavities of the human body such as oral cavity, nasopharynx and laboratory detection.

Why flocked swabs?

The flocking swab deposits nylon fibers on the surface of the medical ABS rod in order in a certain direction through the electrostatic field to form a brush layer. The layers are fully parallel and perpendicular to the surface of the internal rod. The brush head can be used for DNA collection. It can be used for sampling the natural cavities of the human body such as oral cavity, nasopharynx and laboratory detection.

So that there is no absorption hole in the sampling area of the whole sampling swab.

And the sampling sample will not be dispersed and retained in the fiber, which is conducive to faster and more efficient elution.

Traditional cotton swabs can not completely collect and elute samples, while flocking swabs can elute 95% of samples.

Therefore, the use of flocking swabs has great advantages for various sample collection applications.

Nasopharyngeal flocked swab;

Flocked swabs have some advantages;

1. Sampling is comfortable and easy to use;

Flocking swabs now basically use “spray technology”, which vertically attaches millions of nylon fibers to the head of medical ABS swab rod through the flocking process of electrostatic charge.

The function of the vertical nylon fiber is similar to that of a soft brush. The use of this soft brush in the sampling process makes the user feel free of foreign objects. At the same time, the flocking swabs used in different parts adopt different breaking points, and the rod adopts different thickness to make the softness different.

For example, the nose swab is thinner and softer at the upper end of the rod, and the breaking point is longer, which fully conforms to ergonomics.

2. Flocked swab samples release more;

The capillary action between nylon fiber bundles promotes the strong hydraulic absorption of liquid samples. The sample is kept on the surface to make elution easier. It is much larger than the traditional winding cotton swab. The experimental research shows that the collection and release of flocking swab can reach 95% of the sample, while the cotton swab is only about 20%.

Because most of the samples collected by the cotton swab are easy to be intercepted in the fiber matrix layer of the head during release, it is not easy to release or release a small amount.

3. Flocking swab has biocompatibility and is an ideal choice for PCR;

In order to limit the damage to the sample and improve the accuracy of detection, while the flocking swab is PCR compatible and does not contain RNase and DNase.

Operation method of flocked nylon swab:

Take the sampling method of oropharyngeal swab as an example;

1. First, ask the patient to sit down, then let the patient tilt his head back, open his mouth, and make an “ah ~” sound.

2. The sampler fixed the patient’s tongue with a tongue depressor, and used a flocking swab to cross the root of the tongue to the posterior pharyngeal wall, tonsil recess, lateral wall, etc.

3. Wipe repeatedly for 3 ~ 5 times to collect mucosal cells.

4. Slowly take the swab out of the mouth, vertically put it into the virus preservation solution, break the tail of the swab, and tighten the sampling tube to avoid leakage.

5. Send to the laboratory for testing as soon as possible.

Swab flocked matters needing attention:

1. The swab shall be placed vertically in the sampling tube, and shall not be wiped to the bottle mouth to avoid pollution.Viral Transport Medium.flocked swab copan.

2. It is best to send it or send it to the laboratory for inspection on the day of sampling.

3. Before submission for examination, it must be verified that the specimen is consistent with the submission form. The appearance of the sampling tube must clearly write the patient’s name and basic information.

4. The submitted samples must submit (or submit the electronic version in advance) screening information form, inspection form and other materials.

how to collect nasopharyngeal swab?

After several times of nucleic acid sampling and testing, citizens wondered: why do some people require nasopharynx swabs and some people can collect oropharyngeal swabs?  Today, experts from cell medical will explain to you.

What is a sampling swab?

At present, except for special diseases, COVID-19’s nasopharyngeal swabs and oropharyngeal swabs are the most common ways of collecting.

Studies have shown that nasopharyngeal swabs have higher detection rate of COVID-19 nucleic acids than oropharyngeal swabs. Because the nasopharyngeal cavity is relatively closed and the virus is easier to accumulate. However, whether it is oropharyngeal swab or nasopharyngeal swab, the key is that the collection action must be standardized, in place and meet the standards. As long as the acquisition is standardized, both methods can achieve the expected detection purpose.

1. The patient’s head tilts back (about 70 degrees) and persists. 2. Use a swab to estimate the interval from the ear root to the nostril. 3. Insert from the nostril pen to the face. The deepening interval should be at least half of the length from the earlobe to the tip of the nose. Reach the posterior nasopharynx after encountering resistance, stay for several seconds to absorb secretions (generally 15 ~ 30s), and rotate the swab for 3 ~ 5 times. 4. The swab should be gently rotated and taken out, and the swab head should be immersed in a collection tube containing 2ml lysate or cell preservation solution containing RNase inhibitor. 5. Break the sterile swab rod at the top, discard the tail, tighten the tube cover and close it with sealing film.

1. Ask the patient to gargle with normal saline or clear water first.

2. Wet the flocked swab in sterile normal saline.

3. The patient sat down with his head tilted back and his mouth open, accompanied by an “ah” sound.

4. Fix the tongue with a tongue depressor, and the swab jumps over the root of the tongue to the posterior pharyngeal wall, tonsil recess, lateral wall, etc.

5. The bilateral pharyngeal tonsils should be swabbed back and forth with moderate force for at least 3 times, and then the posterior pharyngeal wall should be swabbed for at least 3 times, 3 ~ 5 times.

6. Remove the swab to prevent touching the tongue, pituitary, oral mucosa and saliva.

7. Immerse the swab head into the preservation solution containing 2 ~ 3ml virus.

8. Break the sterile swab rod near the top, discard the tail, tighten the tube cover and close it with sealing film.
