The saliva swab collection kit is a professional tool used for collecting saliva samples from the human body, and it is widely used in the fields of medical testing, disease diagnosis, scientific research, etc. Here is a detailed introduction:

Saliva collection swab: Usually made of materials such as polyester fiber and nylon, it has good water absorption and softness, and can effectively adsorb cells, viruses, bacteria and other components in saliva, and has little irritation to the oral mucosa. The shape of the swab head is designed in various ways, such as round and flat, to adapt to different oral structures and collection needs.
Collection tube: Generally made of plastic, and the tube usually contains preservation liquid. The main components of the preservation liquid include buffer, protein stabilizer, antibiotics, etc., whose function is to maintain the stability of biological components in the sample, prevent microbial contamination and degradation.
Auxiliary tools: Such as disposable gloves, tongue depressors, instructions, etc. Disposable gloves are used for the protection of collectors to avoid cross-infection; tongue depressors can help collectors better collect saliva samples, especially when the collectors’ oral cavity is sensitive or uncooperative; the instructions detail the use method and precautions of the collection kit.

Preparation work: Before collection, the operator needs to wear disposable gloves, check whether the collection swab, collection tube, etc. are intact, and ensure that the preservation liquid in the collection tube is sufficient.
Collect saliva: The collector first rinses the mouth with clean water to remove impurities such as food residue in the mouth. Then, put the saliva collection swab into the mouth, gently wipe or rotate in the areas such as the inside of the cheek and under the tongue to collect enough saliva samples. During the collection process, attention should be paid to avoiding the swab from contacting the teeth, gums and other parts to avoid affecting the sample quality.
Sample preservation: Put the collected saliva swab into the collection tube, ensure that the swab head is completely immersed in the preservation liquid, break the excess part of the swab, and close the lid of the collection tube.
Sample marking and recording: Mark the relevant information of the collector on the collection tube, such as name, gender, age, collection time, etc., and make corresponding records for subsequent tracing and identification.

Non-invasive collection: Compared with methods such as blood collection, saliva swab collection is a non-invasive operation, which will not cause trauma to the collector, and the collection process is relatively comfortable and easy to be accepted, especially suitable for special groups such as children and the elderly.
Simple operation: The whole collection process is simple and easy to understand, and does not require professional medical equipment and technology. It can be operated after simple training, and can be carried out in various places such as homes, communities, and schools.
Good sample stability: The preservation liquid in the collection tube can effectively protect the biological components in the saliva sample to keep it stable within a certain period of time, which is convenient for transportation and storage, and provides a reliable sample for subsequent detection and analysis.

Medical testing: It is used for the diagnosis of various diseases, such as the diagnosis of infectious diseases such as COVID-19, influenza virus infection, and AIDS virus infection, as well as genetic testing of some hereditary diseases.
Drug testing: In the process of drug research and development, saliva samples can be collected to detect the metabolism of drugs in the body, providing a basis for drug efficacy evaluation and dose adjustment.
Oral health research: It is used to detect the microbial community such as bacteria and viruses in the oral cavity, evaluate the oral health status, and study the pathogenesis and prevention and treatment methods of oral diseases.
