Get and stay in front of Covid-19 with Promus Diagnostics’ High Complexity Quantitative Neutralizing Antibody Test – qNAT

Promus Diagnostics’ qNAT (Quantitative Neutralizing Antibody Test) detects the key immune response antibodies that shield the cells from the virus preventing infection propagation.

Many different antibodies are elicited from SARS-CoV-2 (COVID-19) immune response or vaccination, but only a subset handcuff the virus so it can’t take control of the cells and spread.

COVID-19 (SARS-CoV-2) Infections Facts:

  • For the virus to invade the human cells, it needs to attach to the ACE2 receptor with the receptor binding domain (RBD) of the Spike protein.
  • If this interaction is blocked, with a Neutralizing/blocking antibody, the virus can not invade the cell.
