invasive stratification of hepatocellular carcinoma risk in non-alcoholic fatty liver using polygenic risk scores,

Berzuini et al report the observation that nearly half of patients with COVID-19 tested at their blood center had a positive direct antiglobulin test (DAT). However, eluates did not react with any test cells but did react with red cells from other patients with COVID-19 that were DAT negative. This suggests that COVID-19 may modulate the red cell membrane and present novel antigenic epitopes.
