Manufacturer for colloidal gold - COVID-19 IgG Lateral Flow Assay – Genobio

Product Introduction

Virusee® COVID-19 IgG Lateral Flow Assay is a lateral flow immunoassay used for the qualitative detection of Novel Coronavirus IgG antibody in human whole blood / serum / plasma samples in vitro. It is mainly used in the auxiliary clinical diagnosis of novel coronavirus pneumonia.

The novel coronavirus is a positive single-stranded RNA virus. Unlike any known coronavirus, the vulnerable population for Novel Coronavirus is generally susceptible, and it is more threatening to the elderly or people with fundamental diseases. IgG antibodies positive is an important indicator of novel coronavirus infections. Detection of novel coronavirus-specific antibodies will aid clinical diagnosis.

Background and principle

Coronaviruses are a large family of viruses that cause colds and more serious diseases. COVID-19 is caused by a novel coronavirus strain that had not previously been found in humans. Common signs of infection include respiratory symptoms, fever, shortness of breath, and dyspnea. In severe cases, infection can cause pneumonia, acute respiratory syndrome, kidney failure, and even death. There is currently no specific treatment for COVID-19. The main routes of transmission of COVID-19 are respiratory droplets and contact transmission.  Epidemiological investigations have shown that cases can be traced to close contact with individuals with confirmed infection.

Detection of microbe-specific IgM and IgG in circulating blood (a ‘serologic’ test) serves as a method to determine whether a person has been infected with that pathogen, either recently (IgM) or more distantly (IgG).

Various studies have also found that IgM and IgG detection may be a rapid, easy, and accurate way for detection of suspected SARS-CoV-2 cases. Diagnostic accuracy of COVID-19 might be improved by nucleic acid testing in patients with a history of epidemic disease or with clinical symptoms, as well as CT scans when necessary, and serum-specific IgM and IgG antibody testing after the window period.
