Disposable virus sampling tube is mainly used for the collection and preservation of virus samples from throat or nasal secretions, and is one of the important consumables for new coronavirus detection. In response to the new situation of epidemic prevention and control requirements, the launch of disposable virus sampling tube solutions for large-scale nucleic acid testing "speed up".
Why choose special disposable virus sampling tubes, collection, transportation and storage of samples?
The quality of the collected samples is directly related to the subsequent testing. The viral load of the collected samples is not high and gradually decomposes with changes in the living microenvironment. If improper collection tools and preservation liquids are used, it is easy to cause wrong test results and difficult to diagnose
Conditions for excellent disposable virus sampling tubes need to be met.
①Sample validity aspects.
The activity of pathogenic infection factors need to be maintained ;
Meet the sample collection time in the laboratory test ;
To ensure the reliability of the diagnostic test, it is necessary to limit or prevent the proliferation of commensal microorganisms;
Maintaining the integrity of viral antigens and nucleic acids;
Ability to maintain viral activity at ambient conditions.
②Safety aspects.
Disposable virus sampling tubes are loaded with infectious substances, some of which are even highly pathogenic infectious substances. Therefore, the requirements for the packaging containers are very strict and have to meet the safety requirements.
Transport safety: to ensure that the sample does not leak during transport.
Preservation safety: to ensure that the sample does not leak during preservation.
Sampling methods.
1) Pharyngeal swab specimen: wipe the posterior wall and both sides of the tonsils with a special sampling swab and wipe moderately to avoid touching the tongue; dip the head of the swab quickly into the sampling solution, break the swab at the cut-off point where the sampling swab rod is easily broken, and abandon the tail.
2) Nasal swab specimen: gently insert the swab head into the epiglottis on the inside of the nasal cavity with a special sampling swab, stay for a while, and then slowly rotate and withdraw; dip the swab head quickly into the sampling solution, break the swab at the easy break point of the sampling rod, and discard the tail.
The operation can be repeated with another sampling swab if a double-sided sample needs to be taken.
YH-I, YH-II, YH-III preservation fluid preservation effect test YH-I, YH-II, YH-III preservation fluid preservation effect test Packaging form In the packaging form, the biological use of its own advantages, in line with GMP standards in the clean workshop for the preservation of the tube to fill the preservation fluid, and the use of disposable easy-tear package packaging, to avoid contamination, improve product quality and performance In addition, irradiation sterilization is also performed before the product leaves the factory to ensure that the factory product will not contaminate the sample and avoid affecting the final test. In the current epidemic, please pay attention to protection and reduce the gathering.
