An important tool to safeguard your health
Antibodies are protective proteins made by the immune system in response to natural infection or vaccination. Neutralizing antibodies (NAbs) are the subset of antibodies that block entry of a virus into the cell, preventing infection. Recent studies have shown that there is a strong correlation between NAb levels and protection against symptomatic SARS-CoV-2 infection.

How is the test performed?
DxTerity’s CLIA-certified and CAP accredited laboratory uses cutting-edge technology to measure neutralizing antibody levels and identify individuals most at risk, enabling employers to make informed decisions to reduce risk to employee health in the workplace.
How is the test report?
The test report shows a positive or negative result for the detection of COVID-19 neutralizing antibodies. If NAbs are detected, a measurement of an individual’s specific NAb level is also provided.
Test results can be downloaded and printed or downloaded onto a mobile device.

FAQ’s
| Why should employers choose DxTerity’s Neutralizing Antibody Test? |
|
|
As part of our commitment to helping the US get back to work safely, DxTerity is ready to support businesses of all sizes with simple solutions to evaluate and safeguard employee health and wellness. Our laboratory accreditations are based on a demonstration of our ability to provide quality, trusted results. Our secure results portal has been tailored to make it easier for businesses to review results and quickly identify infection risks so that proactive measures can be put in place to protect the workplace. |
| Is this a one-time test? |
|
|
While you can take this test one time to gain insight on your current antibody level to COVID-19, the CDC, FDA and vaccine manufacturers have all acknowledged they do not know how long protection to COVID-19 lasts. Taking DxTerity’s Neutralizing Antibody Test twice per year can give a better understanding of antibody levels as they decrease over time. |
| What if a Neutralizing Antibody Test result suggests that no neutralizing antibodies were detected? |
|
|
Antibodies can take 1–3 weeks to fully develop to a measurable level in a person who has been infected with COVID-19 or has been vaccinated. If the test did not detect neutralizing antibodies in the sample, it indicates that an individual, at the time of testing, did not have a measurable level in their blood. This could be because there was no exposure to COVID-19, no vaccination, not enough or too much time has passed since vaccination or infection, or the immune response could have been suboptimal due to a variety of risk factors. |
| If a Neutralizing Antibody Test results in a high level of neutralizing antibodies detected, does that mean a person is totally safe from contracting COVID-19? |
|
|
Irrespective of neutralizing antibody levels, there is always a risk of infection. There also continues to be several new COVID-19 variants (mutations) that reduce the efficacy of protection acquired by previous infection or vaccination. |
| How is employee health information protected? |
|
|
DxTerity is a California licensed, CAP accredited and CLIA certified clinical laboratory that adheres to all state and federal laws regarding the protection of personal health information (PHI). All data provided to DxTerity is fully encrypted bidirectionally in transit and at rest. |
