Aditxt Submits Two Requests for Emergency Use Authorization to FDA for AditxtScore™ for COVID-19 Tests Which Measure the Quantity and Quality of Antibodies Against COVID-19 and its Variants Including Omicron

Aditxt, Inc. has submitted two EUA applications for AditxtScore™ for COVID-19. This lab-developed blood test provides a more comprehensive profile of the body's immune response to COVID-19. AditxtScore™ for COVID-19 not only indicates levels of protective immunity against the virus, but also seeks to map out the difference in response to its common variants, including Omicron.

Aditxt's EUA submissions are for tests designed to, among other things: (i) reveal levels of antibodies neutralizing COVID-19; and (ii) quantify the level of antibodies that attack various targets of the virus, including the spike and nucleocapsid proteins. The granularity of AditxtScore™ for COVID-19 is of crucial importance as spike protein antibodies are generated in response to the vaccine and natural exposure to the virus. Antibodies to the nucleocapsid protein are, in contrast, only produced in response to exposure or infection by COVID-19.
