Oral Antibody Tests
COVID-19 diagnostic testing conducted in conjunction with COVID-19 antibody testing is proving to be a very effective strategy in addressing the COVID-19 response challenges faced by workplaces, educational institutions, government agencies or wherever large congregate public gatherings occur.
For host organizations (employers, educational organizations, health providers, etc.) testing for antibodies is the next logical step to help guide decisions about moving forward in the response to the COVID-19 pandemic.
Test results play a critical role in the fight against COVID-19 by identifying who has detectable antibodies. Together with other clinical information and guidance from health authorities, these results can assist with decisions on ensuring the safety of employees and customers.
The world's first and only oral swab test.
Greenwarez Global is pleased to introduce a major breakthrough in COVID-19 testing with the game-changing CovAb™ and CovAbScreen™ rapid antibody test kits. These ground-breaking advances in technology are the world’s first and only oral swab rapid antibody tests capable of detecting all three immunoglobulin neutralizing antibody classes (IgA, IgG and IgM) produced as a result of a prior COVID-19 infection or by COVID-19 vaccination.
These non-invasive premium antibody tests require no need for blood draw, nasal swabs, lab work or lab instruments. With a simple swab of the mouth these rapid antibody test can detect the presence of COVID-19 antibodies within 15 minutes.
CovAb™ has received FDA Emergency Use Authorizations (EUA) for point-of-care use in the United States.
