It uses a lateral flow test to determine whether a person has IgG antibodies to the SARS-CoV-2 virus that causes COVID-19. The test uses a single drop of blood obtained from a finger prick ...
It also received EUA for its m2000-based laboratory nucleic acid test for COVID-19. [2] In April 2020, Abbott received EUA for its ARCHITECT IgG laboratory antibody test for COVID-19.
