Is virus sampling with flocked swabs reliable? This article will give you the answer.
I. Introduction to influenza viruses.
Influenza (influenza for short) is an acute respiratory infection caused by the influenza virus and a highly contagious and fast-spreading disease. It is mainly spread through droplets in the air, person-to-person contact or contact with contaminated objects. The typical clinical symptoms are: acute onset of high fever, generalized pain, significant malaise and mild respiratory symptoms. The fall and winter seasons are usually its high season, and the complications and deaths caused are very serious. The disease is caused by the influenza virus, can be divided into A (A), B (B), C (C) three types, A virus often occur antigenic mutation, infectious, rapid spread, very easy to occur in a wide range of epidemics. Type A H1N1 is also a type A. The disease is self-limiting, but in infants and young children, the elderly and the presence of heart and lung underlying disease in patients prone to complications such as pneumonia and other serious complications resulting in death.
Influenza virus caused by the virus is not heat-resistant, 100 ℃ 1 minute or 56 ℃ 30 minutes inactivation, sensitive to commonly used disinfectants (1% formaldehyde, peracetic acid, chlorine-containing disinfectants, etc.) sensitive to ultraviolet light, resistant to low temperature and drying, vacuum drying or -20 ℃ below can still survive. Among them, influenza A viruses often occur antigenic mutations, highly contagious, rapid transmission, highly susceptible to widespread epidemics.
Second, can be used as a flocked swab swabs for influenza virus sampling product characteristics.
1. with extraordinary ability to absorb water washing, can be its table to collect the number of specimens from the traditional sampling swab 20% to 60%, collection of influenza virus, H7N9, H1N1, collection of human respiratory tract infection germs virus, influenza A virus infection collection sample analysis,
2. Over 90% release rate of collected specimens, thus ensuring high reliability of results
3. Different preservation solutions are used for different specimen types
4. Unique breakable design on the plastic rod for easy specimen transport
5. Ethylene oxide sterilization, independent packaging, equipped with virus sampling tubes, culture medium for easy transportation and storage at room temperature
Third, according to the characteristics of the swab we recommend that we sample in the nasal cavity
Package: Individually packaged
Place of origin: Shenzhen, China
Brand: huarikang
Manufacturer: Shenzhen Huarui Kang Biomedical Technology Co.
Uses: genetic testing sampling, molecular diagnosis, genetics, stomatology, cytology, disease science, laboratory, research institute. Forensic, public security system DNA, flu specimen collection, CDC, rapid flu antigen (nose or throat swab)
Details:This test provides a rapid check for signs of influenza A and B viruses in nose or throat secretion samples.
IV. Follow these steps when using the nasal swab MFS-96000BQ for influenza virus collection.
1. Select a swab with a flexible plastic handle and flocked tip.
2. Insert the swab directly into one nostril (not upward) and horizontally into the nasopharynx up to the measured distance on the swab handle.
3. Rotate the swab up to 5 times and hold for 5-10 seconds to collect the sample material.
4. Remove the swab and insert it into a vial containing 1-3 ml of virus transfer medium.
5. Break the swab handle at the scored breakpoint line.
6. Mark the vial with the appropriate patient information.
