Nasopharyngeal Swab Sample (Nasal Swab)
The nasopharyngeal swab: A specimen collection tool used to collect cell samples from the nasopharynx (above the throat).
When a patient develops an upper respiratory tract infection, doctors can use the collected samples to detect it, especially when the patient still has a fever.
In the experiment, technicians can detect common sources of infection, including potential pathogens such as the new crown and swine flu.

Such tests can be uncomfortable for patients, but can quickly identify serious respiratory illnesses, especially those that require isolation or infection prevention measures to protect other patients.
Doctors can use cell cultures to determine the type of current infection. Factory-produced nasopharyngeal swabs cannot use natural substances such as cotton, as they may contain some impurities that will affect the detection.
Nasopharyngeal Swab materials
The nasopharyngeal swabs produced and sold by Cell Medical Company are flocked materials. Learn more about flocked swabs.

CellMedical flocked swabs are famous for their stable and reliable performance and excellent absorption and elution ability.
In general, a caregiver can place a sealed package (safety bag) next to the patient, and the caregiver places a sample container next to the patient, which contains a culture medium that maintains cellular and microbial viability for evaluation. This is the viral transport medium.
Laboratory technicians can detect the source of infection through nasopharyngeal swabs, and they should wear gloves and masks when collecting nasopharyngeal swabs.
Face protection is an effective measure to prevent patients from contracting respiratory diseases.
Nasopharyngeal swab collection
When taking the sample, gently insert the swab into the nose by hand, pushing it all the way to the nasopharynx. Patients often experience discomfort, convulsions, or spasms; for this, they sometimes need to suppress this response by leaning their heads against a wall or pillow.
When the nasopharyngeal swab is fully in, the caregiver can briefly swirl to collect the cell mixture, remove it, and place it in the specimen collection container. (Virus sampling tube)
After the sampler obtains the sample, he should immediately send it to the laboratory for PCR testing.
Waiting or not storing at low temperature may kill microorganisms that may be present in the sample, resulting in false-negative test results.
Patients usually get results within a day or two.
Inspection is capable of scanning for many common microorganisms.
When infectious diseases appear in epidemic areas, nasopharyngeal swabs and other microorganisms can be labelled to detect new crowns, swine flu and other microorganisms.
The doctor can try the test results to guide the patient’s treatment.
They can also help epidemiologists track the movement of diseases in the community, which is very useful for controlling disease outbreaks.
