4.[viral transport medium tube test principle]

On the basis of Hank’s, potassium chloride, magnesium chloride and calcium chloride are added to provide necessary nutrient ions for pathogenic bacteria to make it more specific. The preservation time is longer, the integrity of pathogenic bacteria morphology is preserved to a greater extent, and the extraction rate of pathogenic bacteria is improved.

8.[usage]

Firstly,before sampling, mark relevant information on the label of the sampling tube.

Secondly,use the corresponding sampling flocked cotton swab for sampling.

Then,after sampling, quickly put the cotton swab into the sampling tube, break the part higher than the sampling tube, and tighten the tube cover.

Finally,see the following for specific sampling methods.

a)Nasal swab: gently insert the sampling head into the nasopalatine part of the nasal catheter, stay for a moment, and then rotate it slowly to exit. Immerse the collected specimen into the liquid in the sampling tube, break the excess part and discard it, and tighten the sampling tube cover.

b) Pharyngeal swab: wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with sampling head. Soak the collected specimen in the sampling solution, break the excess part, discard it, and tighten the sampling tube cover.

 9.[precautions]

1. After collecting pathogenic bacteria samples, we should completely insert the disposable sampling flocked cotton swab into the preservation solution to retain pathogenic bacteria to the greatest extent.

2. The collected samples must be fresh and sent for examination in time to avoid the death of pathogenic bacteria.

3. Forbidden to use products with damaged packaging and expiration date to prevent pollution.

Note: For in vitro diagnosis. For virus sampling, transportation and storage.Including COVID-19.

Food can lead to serious events; It has certain irritation to eyes and skin. If it accidentally splashes into eyes, rinse with clean water.

DO you to know about the virus sample preservation solution

CM company take you to know the virus sample preservation solution.

Cell medical (Dongguan) Co, Ltd.,Take you to know the virus sample preservation solution.

Virus sample preservation solution,also known as disposable virus sampling tube.When we first came into contact with this term, we must be very curious.

However,what is  DNA / RNA virus sampling tube？

First of all, virus sampling tube is a liquid that protects the tested substance of the virus by immersing the sampling swab virus sample in the sampling tube. Currently, it is mainly used for the collection, storage and transportation of common virus samples such as COVID-19, HFMV and so on. Medical workers can take tissue samples from the throat or specific areas using throat swabs and nasal flocked swabs. Samplers then store the samples for subsequent clinical trials such as nucleic acid extraction or purification. The virus and related samples can be stored at -70℃ or liquid nitrogen for a long time.

Usually,we divide the virus storage solution into two kinds. the non-inactivated virus storage solution and the inactivated virus sampling tube. The non inactivated type can protect viral proteins and nucleic acids. Maintain virus activity and facilitate culture and detection. Although the inactivated type can make the virus no longer have physiological activity, lose infectivity and pathogenicity, and have the ability to reproduce. Inactivate the virus, eliminate secondary infection,and protect the safety of transportation and testing personnel.

About inactivated sample preservation solution.

There may be a small partner who will question whether the inactivated type will inactivate the virus? How do you check it? Don’t worry, the purpose of using inactivated virus sampling tube is to lyse nucleic acid and detect nucleic acid by subsequent RT-PCR.

After extraction with most commercial kits, the quality of DNA or RNA obtained is good and the yield is high. So,it can complete various gene detection and analysis experiments, such as PCR or qPCR, and save transportation costs.

It is suitable for COVID-19, hfmv and other common virus samples.

About inactivated sample preservation solution.

  • The virus preserved in non inactivated virus sampling tube has better integrity and higher detection rate. Researchers use it for scientific research, including nucleic acid testing.
  • Cryogenic storage without freezing, does not destroy the virus shell, easy long-distance transportation;
  • Application:H1N1 influenza virus and any other Virus swab sampling;
  • The antibiotics in the preservation liquid can effectively prevent bacterial and fungal infection;

    Nasal swab painful

    Nasal swab painful

    Posted on by

    People often feel scared during the sampling process using nasopharyngeal swabs. However, is it really painful to use a nasopharyngeal swab?

    It is certain that nasopharyngeal swab testing does not produce painful symptoms, but some patients may feel uncomfortable.

    The doctor used a medical flocked swab to enter the nasopharynx and then took a small amount of secretions. The hospital can isolate pathogenic bacteria through bacterial culture.

    During the operation of the sampler, the patient will have slight nausea and discomfort, which is generally within a tolerable range. The medical staff’s techniques are gentle and skilled, so there is no pain. We can check the bacteria that cause the infection through nasopharyngeal swabs, and select targeted drugs for treatment based on the results of the tests.

    Which is painful, nasal swab or throat swab？

    In contrast, nasal swabs are more painful. Pharyngeal swab is the behavior that doctors use a medical flocked swab to dip secretions from the throat for monitoring. During the collection of pharyngeal swab, the tested person may have symptoms of nausea and vomiting without other obvious pain. Nasal swab is to insert a cotton swab into the deep part of the nasal cavity to dip secretions for monitoring.

    Why nasopharyngeal swabs are better than oropharyngeal swabs

    • According to reports in the literature, the positive rate of nasopharyngeal swabs is higher than that of oropharyngeal swabs.
    • The patient has good tolerance and can basically take samples without anesthesia after skilled operation
    • The exposure risk of the sampler is lower than that of oropharyngeal swabs.

    FLOCKED SWABS_The most effective sample collection swab.

    Flocked tapered swab have outstanding sample collection and release capabilities, can quickly absorb trace amounts of samples, and release high efficiency, increase in the number of target cells.

    Material: ABS+Nylon flocking

    Flocked tapered swab

    Why flocked tapered swab great in Cells Specimen Collection?

    Flocked Swabs are ideal for collecting a large number of cells and rapid slution of the specimens instantly release the cells into the transport medium.

    It is well recognized and adopted by the diagnostic test kit manufacturers who produce reagents in molecular genetic, forensics, clinical laboratories sectors.

    Spray-on nylon swabs

    short perpendicular fiber strands create an absorbent thin layer open structure.

    Patient friendly

    multiple engineered designs and a custom swab fabrication program maximizes patient comfort and drives proficiency of analyte collection.

    High liquid absorbency

    strong apillary hydraulics between the strands of nylon draws up maximum liquid sample.

    Solid and semi-solid recovery-velvet

    the brush-like texture of flocked nylon helps dislodge, collect and transfer solid and semi-solid materials.

    Rapid automatic elution

    liquid and solid specimen samples are held close to the surface between the nylon strands and spontaneously drains when placed in liquid or onto solid media.

    Entire sample released

    flocked tapered swab no sample entrapment because there is no internal mattress core like traditional fiber wound swabs which disperses and ensnares the sample.
