The SARS-CoV-2 Neutralizing Antibody Rapid Test (COVID-19 Ab) is a rapid chromatographic immunoassay for the qualitative detection of neutralizing antibodies to SARS-CoV-2 in whole blood, serum, or plasma. 

Fast results in 15-30 minutes Rapid antigen MSLRDT120  PRINCIPLE 
The SARS-CoV-2 Neutralizing Antibody Rapid Test (COVID-19 Ab) is for detection antibodies to SARS-CoV-2 or its vaccines. The cell surface receptor angiotensin converting enzyme-2 (ACE2) are coated in the test line region and the recombinant receptor-binding domain (RBD) conjugated with the indicate particles. 

During testing, if there are SARS-CoV-2 neutralizing antibodies in the specimen, it would react with the protein RBD-particle conjugate and not react with the pre-coated protein ACE2. The mixture then migrates upward on the membrane chromatographically by capillary action and would not captured by the pre-coated antigen. The SARS-CoV-2 Neutralizing Antibody Rapid Test (COVID-19 Ab) contains protein RBD-coated particles. The protein ACE2 are coated in the test line region.
