SARS-CoV-2 (COVID-19) IgM/IgG Antibody Fast Detection Kit (Colloidal Gold) is a newly launched fast diagnostic product for fast qualitative test of SARS-CoV-2 IgM/IgG antibody in human serum/plasma/whole blood.
This product has already completed the European In Vitro Diagnostic Medical Devices Directive (IVDD) compliance statement and registration in the European Union, and has been qualified for EU market access.
How it works?
SARS-CoV-2 (COVID-19) IgM/IgG Antibody Fast Detection Kit (Colloidal Gold) adopts colloidal gold-immunochromatography assay (GICA).
Antibody tests involve analysing a patient’s sample (usually blood) for the presence or absence of a particular antibody (qualitative) or for the amount of antibody that is present (quantitative). Antibodies are part of the body’s immune system. They are immunoglobulin proteins that help protect people against microscopic invaders such as viruses, bacteria, chemicals, or toxins.
Each antibody that is produced is unique. It is created to recognise a specific structure on an invading foreign cell or particle.
A nucleic acid test (NAT) is a technique used to detect a particular nucleic acid sequence and thus usually to detect and identify a particular species or subspecies of organism, often a virus or bacteria that acts as a pathogen in blood, tissue, urine, etc. NATs differ from other tests in that they detect genetic materials (RNA or DNA) rather than antigens or antibodies. Detection of genetic materials allows an early diagnosis of a disease because the detection of antigens and/or antibodies requires time for them to start appearing in the bloodstream.
Polymerase chain reaction (PCR) is a method widely used in molecular biology to rapidly make millions to billions of copies of a specific DNA sample allowing scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detail. PCR was invented in 1983 by Kary Mullis. It is fundamental to much of genetic testing including analysis of ancient samples of DNA and identification of infectious agents.
ZeroViurs portable sterilization bar is a newly virus-prevention tool, which exterminate the infectious bacteria, influenza virus and other harmful bacteria around us. In order to know how it works, let us study how virus infect us first.
How does the virus infect our body?
Let’s take the COVID-19 as an example. When the COVID-19 infects the human body, it enters the throat through the human’s nasal cavity and mouth, and further spread to the trachea and thinner bronchial tubes.
