Specimen Collection Swab
Disposable Specimen Collection Swab is suitable for the collection of microorganisms, which can assist hospitals or laboratories in virus detection or research virus sampling.
For disease detection in the human oral cavity or nasal cavity.
To collect oral epidermal cells of nasal virus samples, the cells or samples are stored in a collection tube and then transferred to a laboratory for testing.
Specimen collection swab how to use?
Step 1: Prepare the required materials to ensure that you do not have a cold or runny nose so as not to affect the test results, tear open the Cell medical flocked swab sampling kits, hold the handle and gently insert the sampling swab into the nasal cavity.
Step 2: Gently rotate the swab deep into the nasopharynx for 3-5 turns, and then take it out slowly. Be careful to handle it gently, and do not touch the head of the swab with your hands or other objects.
Step 3: Put the extracted sample into the sample collection tube, break the handle, seal the cover of the sample collection tube to ensure sealing.
And then complete the sampling at random.
What is a virus sampling swab kit?
The virus sampling swab set is a virus sampling and transfer product for virus nucleic acid detection.
Including a sampling swab (Specimen Collection Swab), a sampling tube and a virus preservation solution.
It can be used for nasopharyngeal and oropharyngeal covid-19 sampling swab sets, the virus preservation solution is also called virus transport medium (Viral Transport Media), referred to as VTM.
According to the composition and function of virus preservation solution.
Including non-inactivated type and inactivated type.
Non-inactivated virus sampling swab kits
In the non-inactivated new coronavirus sampling swab kit. The components of the virus preservation solution usually include nutrients (such as salts, proteins, glucose), bacteriostatic agents, buffers, phenol red indicator, etc. required for the survival of the virus.
This virus preservation solution can maintain the activity of the virus to the greatest extent and not only for virus detection but also for virus culture and isolation.
Inactivated virus sampling swab kits
In the inactivated new coronavirus sampling swab kit, the components of the virus preservation solution usually include buffers, virus lysing agents (usually guanidines), surfactants, etc. This preservation solution can directly lyse the virus to release nucleic acid, which is convenient for subsequent nucleic acid detection.
What we need to pay attention to is that whether it is an inactivated type or a non-inactivated type, the virus sampling tube is sterile.
There are no other microorganisms that could cause false detections due to viral breakdown or other influences after sampling.
After flocked swab sampling, if a collection tool or preservation solution of poor quality is used, it will affect the subsequent test results and even cause false positives for misdiagnosis.
Different types of preservation solutions have their advantages and disadvantages according to different situations.
Recommended using a virus preservation solution of good quality.
