one aspect of the study involved using remnant blood samples from patients who visit UAMS clinics, including three regional campus clinics, and have their blood drawn for health reasons other than COVID-19. The samples, which would be discarded otherwise, are being collected and shipped to UAMS from across the state for the antibody test, which was developed in the laboratories of Boehme and Forrest.
Of 1,220 adult blood samples tested so far, 43 were positive, or 3.5%. From this analysis, samples were collected in July and August 2020. While low overall, Kennedy said, there are noteworthy differences across racial and ethnic groups:
Hispanic (13 of 73 positive = 17.8%)
Black/African American (21/501 = 4.19%)
White/Caucasian (7/550 = 1.27%)
