Classified by tip raw materials, our core swab lineup includes flocked swabs, sponge swabs, polyester fiber swabs and ATP detection swabs, each engineered with exclusive material advantages to match diverse testing demands. Electrostatic flocked swabs adopt vertical nylon fiber flocking technology without inner fiber cores, featuring ultra-high cell capture rate and over 95% specimen elution efficiency, perfectly compatible with PCR, antigen detection and molecular diagnostic workflows. Open-cell medical sponge swabs boast strong liquid absorption, soft contact and low irritation, ideal for collecting abundant mucus and body fluid samples. Polyester fiber swabs are free of inhibitory substances for nucleic acid testing, lint-free and stable during long-term storage, widely applied in routine microbial culture sampling. ATP swabs are tailor-made for rapid surface hygiene monitoring, capable of efficiently capturing residual microorganisms to support instant sanitation assessment in medical, catering and pharmaceutical workshops.

By clinical sampling sites, we supply a comprehensive spectrum of human specimen collection swabs: throat swabs, nasal swabs, oral swabs, oropharyngeal swabs for respiratory virus screening; cervical swabs and gynecological swabs for women’s health cytology and HPV testing; rectal sampling swabs for enteric pathogen and multi-drug resistant bacteria screening. All human body sampling swabs come with optional break-point shafts, flexible soft tips and single sterile packaging to reduce patient discomfort and cross-contamination risks during sampling.

For laboratory and industrial testing scenes, Huachenyang provides environmental sampling swabs, DNA sampling swabs and universal sterile swabs. Environmental sampling swabs are designed for surface microbial collection on equipment, countertops and public facilities, supporting food safety and hospital environmental disinfection monitoring. Our DNA swabs optimize epithelial cell collection from oral mucosa and skin, meeting strict standards for paternity testing, forensic human identification and gene sequencing experiments. Every sterile swab undergoes strict ethylene oxide sterilization, batch traceability inspection and biocompatibility testing before delivery, eliminating interference to test reagents and guaranteeing accurate, repeatable experimental results.

All Huachenyang swabs comply with international medical device quality standards, supporting customized shaft lengths, tip sizes, independent peel pouch packaging and OEM private labeling services. From routine clinical diagnosis, women’s health screening, respiratory infectious disease testing to food hygiene monitoring, forensic DNA extraction and industrial surface ATP testing, our full-range sampling swabs form a one-stop supply solution to satisfy global customers’ diversified procurement needs. With mature manufacturing capacity and rigorous quality control systems, Shenzhen Huachenyang Technology Co., Ltd. persists in developing stable, cost-effective sterile sampling swabs to serve global medical and bioscience industries.

Anterior Nasal Swab

The anterior nasal method is done with a swab to collect specimen from the nasal membrane. Insert the anterior nasal swab into the nostril about 0.5-0.75 inch deep and rotate for 10-15 seconds while touching the sides of the nasal wall.

while touching the sides of the nasal wall is rotated for 10-15 seconds in one nostril, then with the same swab, collected the same way in the other nostril. Because this method is less invasive, it is usually more comfortable for the patient—and also the method used when self-testing.

Swabs used for nasal sampling typically have a medium-sized tip made of an absorbent substance, most regularly flocked fibers, spun polyester, or medical-grade foam. Typically, ABS is used for the nasal swab handle.

Nasopharyngeal Swab

The nasopharyngeal collection method collects a sample from the nasopharynx (upper part of the throat behind the nose). The healthcare practitioner gently supports the patient’s head while using nasopharyngeal swab as it slowly and carefully insert rearward into the nostril to prevent scratching and bleeding. Gently rotate and slowly withdraw the swab once it has touched the posterior wall of the nasopharyngeal. It might not be necessary to take a sample from both nostrils if the tip of the swab is fully saturated with the specimen. This method tends to be less comfortable for the patient and should only be performed by a healthcare practitioner.

A swab used for nasopharyngeal is one designed with a miniature tip made of an nylon flocked material and one with a thin, flexible handle usually made of soft plastic or wire.

It should be noted that nasopharyngeal swab sampling should be avoided in patients with moderate allergic rhinitis, nasal malformations (such as a curved nasal septum), recent nasal bleeding symptoms, within three months of a recent nasal surgery, blood diseases, long-term anticoagulant medications, and other relevant medical histories and risk factors.

Since the pharynx is more susceptible to external bacterial infestation when the body’s systemic or local resistance decreases, it can lead to infection and eventually lesions. This is when doctors need to use oropharyngeal swabs to collect cells and viruses from pharyngeal samples for testing to understand the patient’s health condition.

In recent years, oropharyngeal swabs have also been widely used for COVID-19 nucleic acid testing.

The advantages of flocked oropharyngeal swabs

• GMP factory production, clean and odorless
• Using the latest flocking technology, the fiber is firm and uniform
• Flocked swabs have strong sample collection ability and high release rate
• Flocked sampling head is soft and will not make the subject feel uncomfortable
• Designed with break points to help staff handle and store samples more easily
• Sterile disposable packaging to ensure product safety

Proper use of oropharyngeal swabs

1. Check that the packaging of the oropharyngeal swab is intact
2. Clean hands, then tear the package, avoiding touching the swab sampling head
3. The subject looks up and opens the mouth wide to expose the pharynx
4. The sampler will take the oropharyngeal swab deep into the mouth and wipe the pharyngeal and palatal arches or tonsillar region with gentle movements
5. Remove the flocked swab and quickly place the swab into the virus transport medium, breaking the swab at the point of fracture
6. After tightening the cap, store the virus sampling tube at the prescribed temperature and send it for testing as soon as possible.

Top 5 advantages of nylon flocked swabs

1. Flocked swabs can collect a large number of samples

Nylon flocked swabs are the best choice for rapid diagnostic tests because they provide better collection of cells or organisms.

2. Enhanced diagnostic sensitivity

Patented flocking technology turns each strand of fiber into a velvety brush, thus allowing the swab to create hundreds of thousands of contact points for better sample collection and release. The increased number of target cells (compared to non-flocked swabs) helps improve the sensitivity of rapid diagnostic tests.

3. High sample release rate of flocked swabs

Huachenyang’s flocked swabs are tightly bonded to the handle and do not contain an internal fabric or other inner core that absorbs the specimen, enabling a greater volume of specimen to be collected and retained. This not only provides more specimens, but also allows for a more rapid and complete release of the specimen into the liquid medium.

4. Proprietary multi-length flocked fibers

The flocked swab’s proprietary multi-length lint fibers form a web-like structure that allows for the collection and retention of more specimens than traditional cotton swabs, polyester swabs or rayon swabs. In contrast, the inner core of a regular swab will tend to lock up the specimen, making it difficult to elute the specimen into the media.

5. Easy handling, preservation and transport

Most oral, oropharyngeal, and nasopharyngeal flocked swabs have pre-made break points so you can easily break the handle before placing the swab in the tube. Sterile flocking swabs will also come with transport materials such as dry transport tubes and media-filled transport tubes. After sampling, it can be easily completed for storage and transport.

In short, flocked swabs can better meet the sample collection needs of various laboratories, hospitals and other institutions, and are the preferred tool for specimen collection and elution.

Intertek’s organization code under the MDD directive is 0413 (MDD is the old CE directive, and the new MDR regulation has been mandatory since 2021-5-26), and the organization code under the new MDR regulation is 2862.

Products that have obtained CE certification can be listed in European countries and can be sold in countries that recognize the EU CE certification.
