How is the diagnosis of covid-19 carrier?

The novel coronavirus infection cases of pneumonia are newly diagnosed every day. The new data of the confirmed and suspected cases and the judgement of the epidemic situation have become the common behavior of people during this Spring Festival holiday. So, how is each new confirmed case confirmed?

 

The novel coronavirus, influenza virus, hand foot and mouth disease virus and other common virus samples are collected, preserved and transported. Pharyngeal swab, nasal swab or tissue samples of specific parts can be collected, and the stored samples can be used for subsequent clinical trials such as nucleic acid extraction or purification.

Virus preservation solution (inactivated)

[collection method]

1. Pharyngeal swab: wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with two plastic swabs with polypropylene fiber heads at the same time, immerse the swab head into a tube containing 3ml virus preservation solution (isotonic salt solution, tissue culture solution or phosphate buffer solution can also be used), discard the tail, and tighten the tube cover.

 

2. Nasal swab: gently insert a plastic rod swab with polypropylene fiber head into the nasal cavity and palate in the nasal meatus, stay for a while, and then slowly rotate to exit. The other side of the nostril was collected with the same method. Immerse the two swabs into the same tube containing 3ml of sampling solution, discard the tail and tighten the tube cover.

 

3. Nasopharynx extract or respiratory tract extract: extract mucus from nasopharynx or respiratory tract secretion from trachea with collector connected with negative pressure pump. Insert the collector's head into the nasal cavity or trachea, connect the negative pressure, rotate the collector's head and exit slowly, collect the extracted mucus, and flush the collector with 3ml sampling solution once (or connect a pediatric catheter to a 50ml syringe to replace the collector).

 


[product advantages]

The system contains high-efficiency virus lysate, which can inactivate the virus immediately after sampling and effectively prevent the risk of secondary infection.

 

It contains RNase inhibitor, which can protect the viral nucleic acid from degradation to the maximum extent and greatly improve the efficiency of nucleic acid extraction.

 

The product can be stored at room temperature for 12 months before sampling, and for one week after sampling. It has good tightness, convenient storage and transportation, and saves transportation cost.

 

The product is equipped with two sampling rods to improve the sample collection quantity and effectively avoid insufficient sample collection and low concentration sample missing

 

The 5ml centrifuge tube can avoid the contamination of the pipette during the later sample transfer.
