Frequently Asked Questions

The AditxtScore technology platform provides a personalized, comprehensive profile of the immune system.
AditxtScore is supported by a combination of technologies that were invented by researchers at Stanford University and licensed by Aditxt, scientists at Aditxt’s R&D facility in Mountain View, CA, and scientists in Pearsanta’s clinical facility in Richmond, VA.

It is a blood test (i.e., assay) that measures your immune response to the SARS-CoV-2 virus or vaccination.

An immune response means that your body’s immune system has been exposed to, activated by, and prepared to mount a defense response to the SARS-CoV-2 virus. This response is measurable by AditxtScore. Click here to learn more about COVID-19 immunity in general.
Antigen testing by PCR is used to determine active infection status, while antibody testing determines one’s immune response to the virus or vaccination. As we move through this next phase of the pandemic, understanding one’s own immune status is also important. AditxtScore for COVID-19 provides a comprehensive evaluation of the immune response to the virus or vaccine, allowing individuals to know if prior infection or vaccination has generated the anticipated response. Talk to your healthcare provider about which test is right for you.

AditxtScore for COVID-19 assesses multiple antibody types against multiple SARS-CoV-2 antigens with speed and accuracy. It offers a view of multiple immune parameters in a single test, eliminating the need for multiple test runs.

AditxtScore for COVID-19 is also designed to measure levels of neutralizing antibodies, which block the path that SARS-CoV-2 uses to enter the cells. Levels of neutralizing antibodies have been used as an indicator of the effectiveness of antibodies to prevent the virus from infecting our cells. The AditxtScore platform utilizes a proprietary algorithm to analyze and translate clinical and serological data into meaningful and actionable information for individuals.

Our immune monitoring technology can help individuals make data-driven decisions on the timing of vaccines and boosters by answering*:

  • Have you developed an immune response based on past exposure to the SARS-CoV-2 virus and/or COVID-19 vaccine?
  • Is there evidence you have had a prior SARS-CoV-2 infection?
  • Have you developed a neutralizing immune response to original viral strains of SARS-CoV-2?
  • Have you developed a neutralizing immune response to the omicron variants?

*AditxtScore has not been authorized by the FDA to evaluate a person’s level of protection from COVID-19 or future SARS-CoV-2 infection.

It is performed through a standard blood draw. You do not need to fast. Just be well hydrated so that veins will be easier to find. It is recommended that you consume at least 12 oz of water in the hour before getting your blood drawn.

AditxtScore for COVID-19 is offered through authorized channel partners.

Please verify coverage with your local provider to determine coverage and costs.

AditxtScore for COVID-19 may be FSA/HSA eligible. Some FSA/HSA benefits coordinators, however, might deny reimbursement; consider checking with your benefits coordinator to see if your FSA/HSA covers the AditxtScore test before your appointment.

By assessing multiple antibody types against multiple SARS-CoV-2 antigens, AditxtScore for COVID-19 indicates whether you have been exposed to the virus or vaccine and generated an immune response likely to neutralize it. AditxtScore cannot guarantee you will not become infected in the future; however, a positive immune response suggests you can have increased resistance to infection if exposed to the COVID-19 virus again.

Individuals should not use the results from any test as an indication they can stop taking precautionary measures to protect themselves and others. We encourage you to follow CDC guidelines and local, state and federal rules and regulations.

AditxtScore immune monitoring can show whether vaccination has resulted in an immune response that is designed to protect you from the virus. Knowledge of your immune status may provide insight with respect to your future response to an exposure to SARS-CoV-2.

Please consult CDC guidelines and your healthcare provider regarding whether you should be vaccinated against SARS-CoV-2.

Immune status may change over time. Regular monitoring of your immune status every three to six months can help provide information about changes that may occur over time. Consult with your healthcare provider on appropriate testing intervals.

At this time, the duration of immunity from any of the COVID-19 vaccinations is unknown. Please discuss this topic with your healthcare provider.
