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.

Neutralizing antibodies1 are like the “special forces” of the immune response disarming the virus at just the right point before it can attack our cells.

The immune system does not know how best to attack SARS-CoV-2, so it generates different types of antibodies in an attempt to stop the infection. Similar to throwing darts at a dart board, many antibodies don’t hit the bulls eye. The QNAT measures the bulls eye antibodies that stop the virus from binding to cells and propagating infection.

SARS-CoV-2 Vaccines and active immune response generate Neutralizing antibodies. The QNAT specifically quantifies the presence of Neutralizing antibodies contained in the patient’s blood sample

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.

1) Neutralizing antibodies have been shown scientifically to block the mechanism of infection.
