Why use sampling tools？
At present, the global New Coronavirus epidemic has reached a critical stage. The most reliable means of rapid diagnosis is still positive for nucleic acid detection. There has been a great breakthrough in the diagnosis of COVID-19, but clinicians, especially the laboratory doctors, still face the following serious problems:
1. Safety of specimens
The majority of “angels in white”, especially the laboratory doctors, are always facing the risk of virus infection.
Although there are various protective equipment, the risk of infection will increase if we can’t ensure the safety of specimens. Therefore, it is very important to ensure virus inactivation and the safety of collected samples.
2. False negative test results
The existence of false negative puzzles the clinic and affects the accuracy of diagnosis. The biggest problem is sample collection and preservation. The New Coronavirus infection prevention and control program (Fifth Edition) has been published to collect nasal swabs, throat swabs, sputum, lower respiratory tract secretions, blood and feces. The incorrect way of collecting and storing samples will lead to the degradation of viral RNA and directly lead to the false negative test results.

Sampling steps of new virus collection tube
1) The collection personnel shall be qualified through biosafety training and have corresponding experimental skills. Requirements for protective packaging of sampling personnel: N95 and above protective masks, goggles, one-piece protective clothing, double-layer latex gloves, waterproof boot covers, etc. in case of direct contact with the specimen, the protective equipment shall be replaced in time.
2) Sample type: pharyngeal swab and nasal swab.

Pharyngeal swab collection method: wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with a plastic rod swab with polypropylene fiber head
Nasal swab collection method: gently insert a plastic rod swab with polypropylene fiber head into the nasopalatine part of the nasal canal, stay for a moment, and then slowly rotate and exit. Take another plastic rod swab with polypropylene fiber head and collect the other nostril wall in the same way.
3) Specimen preservation: immerse the swab head into the tube containing virus preservation solution, discard the handle along the folding point of the sampling swab, and tighten the tube cover.
Notes
The tube containing virus preservation solution another name isvirus sampling tube.
Virus preservation solution is also called virus transport medium.VTM.
