Measuring Antibody Levels Allows You to
Better Understand an Individual’s Immune Response

 

ProterixBio offers testing services that measure levels of antibodies against the receptor binding domain (RBD) of the spike protein of the SARS-CoV-2 virus. We also offer a test that detects antibodies to the S1 domain of the spike protein of the SARS-CoV-2 virus. Antibodies to these antigens are associated with neutralizing activity.

  • SARS-CoV-2 antibody tests are intended for individuals that have had or suspect they have had COVID-19 but are no longer symptomatic. Typically, it takes at least 10 days after the onset of symptoms for IgG levels to be detectable.
