One Step Test for SARS-CoV-2 Total Antibody / Neutralizing Antibody (Colloidal Gold)

—— SARS-CoV-2 neutralizing antibody testing can be used as an aid in identifying individuals with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection, it should not be used to diagnose acute SARS-CoV-2 infection.

Basic Information

Intended Use

One Step Test for SARS-CoV-2 Total Antibody /Neutralizing Antibody (Colloidal Gold) is intended for in vitro qualitative detection of SARS-CoV-2 total antibody and circulating neutralizing antibody in serum, plasma or whole blood samples. The test is only used for professional and laboratory use, not for home testing.


In order to infect a human cell, SARS-CoV-2 utilizes S protein on its surface to bind to the human ACE2 receptor on the surface of human cells. Upon entry into the cell the virus replicates causing the immune system to respond by producing different types of antibodies. These include virus-neutralizing antibodies (NAbs) which are crucial to protect the human body from future infections.

Detection Method: Colloidal Gold

Sample Type: Serum, plasma or whole blood 

Reaction Time:  10-15 min
