The application effect of flocked swabs in nucleic acid testing is as follows

High – efficiency sample collection

• The special structure of flocked swabs gives them distinct advantages in collecting nucleic acid samples. The nylon fibers on the head of the swab form a fluffy structure through electrostatic flocking, which greatly increases the contact area between the swab and the sampling site. During the collection process, it can more effectively adsorb cells, viruses, and other pathogens, thereby increasing the amount of nucleic acid collected. For example, when conducting nucleic acid tests for COVID – 19, using flocked swabs can better collect cells containing viral nucleic acid from the nasal or throat regions, increasing the positive detection rate.
• Compared with traditional swabs, flocked swabs can reach into narrower and more concealed areas for sampling. For instance, when sampling from the nasal cavity, their fine fibers can better access the folds of the nasal mucosa, capturing more hidden viruses or bacteria and ensuring sufficient nucleic acid samples are collected, reducing the possibility of missed detections.

Good protection of nucleic acids

• When collecting nucleic acid samples, flocked swabs use a gentle adsorption method instead of the scraping or wiping method of traditional swabs. This approach can minimize damage to nucleic acids and maintain their integrity. Since nucleic acids are relatively fragile biological macromolecules, excessive scraping or wiping may lead to breaks in the nucleic acid strands, affecting subsequent test results.
• During sample transportation and storage, flocked swabs can also provide good protection for nucleic acids. Their fibers can stably adsorb nucleic acids, preventing degradation due to shaking or other factors in the preservation solution, ensuring the quality and activity of nucleic acids before testing, which is beneficial for improving the accuracy of nucleic acid testing.

Strong sample – release ability

• When the collected nucleic acid samples need to be released from the flocked swab into the testing reagents, flocked swabs demonstrate good sample – release capabilities. The adsorption force between the fluffy – like fibers and the samples is moderate. Under appropriate conditions, nucleic acids can be quickly and fully released from the swab and mix well with the testing reagents, ensuring that the nucleic acids can be accurately detected.
• In contrast, traditional swabs may have issues with incomplete sample release, causing some nucleic acids to be unable to participate in the testing reaction, thereby affecting the accuracy of the test results. Flocked swabs can effectively solve this problem, improving the sensitivity and reliability of nucleic acid testing.

High testing accuracy

• Due to the advantages of flocked swabs in sample collection, protection, and release, they can provide high – quality samples for nucleic acid testing. High – quality samples can ensure the accuracy of nucleic acid testing and reduce the occurrence of false – negative and false – positive results. During the COVID – 19 pandemic, the widespread use of flocked swabs provided strong support for accurate diagnosis and prevention and control of the epidemic.
• In addition, flocked swabs have good chemical stability and are unlikely to have chemical reactions with testing reagents, nor will they interfere with the nucleic acid testing process, further ensuring the accuracy and reliability of the test results.

Strong versatility

• Flocked swabs are not only applicable to COVID – 19 nucleic acid testing but can also be widely used in nucleic acid testing for other viruses, bacteria, and other pathogens. Whether it is the detection of respiratory infectious diseases, sexually transmitted diseases, or other infectious diseases, flocked swabs can play their advantages, providing a strong basis for disease diagnosis and treatment.
• At the same time, flocked swabs have good applicability in different testing scenarios and among different populations. Whether in professional medical institutions such as hospitals and disease control centers, or in community testing sites, customs ports, and other places, flocked swabs can be conveniently used for nucleic acid sampling, and they are suitable for people of different ages and physical conditions.

Flocked swabs have the advantages of efficient sample collection, good nucleic acid protection, strong sample – release ability, high testing accuracy, and wide versatility in nucleic acid testing. They are very suitable sampling tools for nucleic acid testing and provide important guarantees for the accuracy and reliability of nucleic acid testing.
