Analysis of platelets adhesion to fibrinogen. Quantification (upper panel) and representative bright field microscopic images (lower panel) of adherent platelets in the presence of sera from healthy control or ICU control and ICU COVID‐19 patients with and without pretreatment with the AKT (BAY) and the PI3K (BYL) inhibitors (scale 10 µm). Activation with TRAP‐6 served as positive control. The % of adherent activated platelets per field was determined from five different microscopic fields. The data are presented as mean ± standard error of mean *p < .05
