Novel Coronavirus (2019-nCoV) Detection Kit

Summary and explanation

Respiratory infections caused by viruses appear mainly in children, the elderly and immunosuppressed patients. The main viruses of respiratory infections are known as influenza viruses, parainfluenza viruses (PIV), Respiratory syncytial virus (RSV), enterovirus, adenovirus, etc. In recent years, respiratory infections of Rhinoviruses, coronaviruses and metapneumoviruses (MPV) have increased, and Bocavirus has been included in the main respiratory virus tests.

The coronavirus is a virus that can infect animals and humans. There are six known coronaviruses that can infect humans. Four of them are known as viruses that cause illnesses like the common cold, and the other two are MERS-CoV (Middle East respiratory syndrome coronavirus) and SARS-CoV (severe acute respiratory syndrome) Coronavirus Syndrome), which have been fatal to humans.

SARS-COV-2, which originated in Wuhan, China in 2019, is transmissible between humans, with up to 14 incubation days, and has been reported to have a lower mortality rate and a higher incidence than SARS-CoV or MERS-CoV. Sequencing of the virus revealed that SARS-CoV-2 was 89.1% homologous to SARS (severe acute respiratory syndrome) derived from shakes, such as coronaviruses, bat-SL-CoVZC45, bat-SL-CoVZXC21), and 79% homologous to SARS-CoV. It is also very important to accurately diagnose COVID-19, as it has sequences similar to viruses of the same genus.

Respiratory virus testing requires the selection of appropriate test methods based on the characteristics of the hospital patient population and laboratory conditions. Antigen test, virus culture and molecular. Biological methods have been used to detect viruses. Among them, the molecular biological method that uses reverse transcription-polymerase chain reaction (RT-PCR) is analytically very sensitive and is recognized as a standard method for detecting viruses that cannot be cultured or that exist in low concentrations.

Recently, One-step RT-PCR, in which reverse transcription and polymerase chain reaction (PCR) amplification can be performed in a tube, allows the precise identification of many viruses. The DiaPlexQ ™ Novel the Coronavirus (2019-nCoV) Detection Kit is a real-time RT-PCR test intended for the qualitative detection of SARS-CoV-2 nucleic acid extracted from nasopharyngeal swabs, oropharyngeal (throat) swabs, anterior nasal swabs, middle turbinate nasal swabs, nasal aspirates, nasal washes, bronchoalveolar lavage fluid (BAL) and sputum.
