Colloidal Gold

According to the on-set time of disease, detection application site, clinical value requirements, users and target population, the reagents for COVID-19 detection include rapid test and routine test, of which the rapid test can be divided into serological and antigen tests, while the routine detection is generally PCR.

Genrui provides comprehensive solutions for COVID-19, including colloidal gold rapid test kit and routine tests.

There are two types of tests for COVID-19. Viral (antigen) test shows if you have a current infection, and antibody test shows if you've been previously infected. What's more, a new type of serological test aims to indicate the presence of specific antibodies against virus invasion - Neutralizing antibody (NAb). The NAb test is also available now, which will guide macro epidemic prevention procedures, as well as personal health protection in the near future.

Colloidal Gold FAQs

Q

What is the difference between the IgG Antibody test and the Spike Protein Antibody test?

IgG COVID-19 Antibody (Blood Test):

This was the first antigen test and antibody test developed for COVID-19 – it potentially identifies antibodies created by you in response to an infection in order to fight the COVID-19 virus. It does NOT test for antibodies made in response to COVID-19 vaccination.

Spike Protein COVID-19 Antibody (Blood Test):

This test potentially identifies antibodies created by you in response to vaccination against the COVID-19 virus. It can also detect antibodies made in response to a COVID-19 infection.

Q

What is the Spike Protein Antibody test?

A test for antibodies made against the spike protein of the COVID-19 virus.

Q

What does the spike protein antibody test detect?

It can also detect antibodies made in response to a COVID-19 infection. What does the Spike Protein Antibody test detect? - The body makes a class of proteins called antibodies which bind to organisms (i.e. COVID-19 virus) in order to fight off infection.

What is the Spike Protein Antibody test?

- A test for antibodies made against the spike protein of the COVID-19 virus.

Q

What does the Spike Protein Antibody test detect?

The body makes a class of proteins called antibodies which bind to organisms (i.e. COVID-19 virus) in order to fight off infection. Our bodies make multiple different antibodies which bind selectively to various components of the COVID-19 virus. We now have blood tests to detect two of these distinct antibodies, one of which is the Spike Protein antibody.

Q

What are neutralizing antibodies?

A neutralizing antibody (NAb) is an antibody that is responsible for defending cells from pathogens, which are organisms that cause disease. They are produced naturally by the body as part of its immune response, and their production is triggered by both infections and vaccinations against infections.

Neutralizing antibodies can result in lifelong immunity to certain infections and can be used to see if a person has developed immunity to an infection after they have recovered from it.

Q

How are neutralizing antibodies made?

Antibodies are made by B-cells in the bone marrow. When B-cells are created, they begin to produce antibodies that will bind to specific antigens.

Q

What is in the covid-19 RT PCR test kit?

The contents of the COVID-19 Nucleic Acid RT-PCR Test Kit are sufficient for 20 or 100 reactions.

The kit consists of a PCR reaction solution, an enzyme reaction mix, a positive control, and negative control.
