Neutralizing antibody (NAb) is antibody that protect cells from pathogens (disease-causing organisms). They are part of the body’s natural immune response, and their production is triggered by infections and vaccines against infections. Neutralizing antibodies can lead to lifelong immunity to certain infections, and can be used to see if the body have developed immunity to infections after they have recovered from the infection.

INTERPRETATION OF RESULTS -Positive sign (+): Only C line is displayed, or T line is equal to or weaker than C line. This indicates the presence of SARS-CoV-2 neutralizing antibodies in the sample. -Negative sign (-): When the intensity of T line is stronger than C line, both T line and C line will appear. This indicates that there is no SARS-CoV-2 neutralizing antibody in the sample, otherwise the titer of SARS-CoV-2 neutralizing antibody is very low.
