As a pioneer in nucleic acid testing, disposable viral sampling tubes play an important role in nucleic acid testing. How much do we know about it? Today, take you through the following points to quickly understand the disposable virus sampling tube.
What is a disposable virus tube?
According to the relevant laws and regulations, virus sampling tubes belong to the medical device products, most domestic manufacturers according to a class of products for the record, few companies according to the second class products for registration. Moreover, in order to meet the urgent needs of epidemic prevention in various countries and regions around the world, most enterprises apply for Class I filing permits through "emergency channels". It is a set of centrifuge tubes for sampling and transporting viruses such as influenza virus and hand, foot and mouth disease virus, also known as specimen transport tubes. Now it has become a commercial product.
The use of disposable virus sampling tubes:
①For monitoring and sampling of infectious pathogenic microorganisms in the CDC part and clinical part. It is suitable for sampling viruses such as influenza virus, hand, foot and mouth disease virus, and mycoplasma, chlamydia and mycoplasma.
②For transporting nasopharyngeal swab specimens or site-specific aligned specimens from the sampling site to the testing laboratory for PCR extraction and testing.
③Used to preserve nasopharyngeal swab specimens or site-specific arranged specimens for necessary cell culture.
Precautions for use of disposable virus sampling tubes:
①Sampling with virus sampling tubes should be sent quickly for testing. They should be transported immediately after collection at a low temperature of 2~8℃. Virus samples can be placed at 2~8℃ for a short period of time for 48 hours. Long-term storage should be kept at a low temperature below -20°C, -70°C or -196°C.
②The collection of virus samples should be carried out in strict accordance with the sampling procedure, so that the sampling position is accurate and the sampling intensity is uniform and appropriate, otherwise the positive rate of virus isolation will be affected.
③Prohibit direct contact with the collected patient and prohibit sampling of the patient with a wet swab.
④Only used for sampling of virus samples, strictly prohibited for sampling of bacterial samples. The sampling solution itself contains antibiotics that can inhibit bacteria.
⑤ Do not use if the product has expired or the packaging is damaged.
⑥When viral sampling tubes being sampled are transported at inappropriate temperatures, they can cause bacteria and mold to multiply, and the antibiotics in the previous sampling solution will completely inhibit the microorganisms in the sample.
