Evaluation of Function and Biochemical Parameters of Platelet Concentrates (<scp>PCs</scp>) Prepared From Blood Donors With a History of <scp>COVID</scp>‐19 During the Platelet Storage

PC from donors recently recovered from COVID-19 exhibited a decline in aggregation in response to both collagen and arachidonic acid; however, the reduction in arachidonic acid-induced aggregation was particularly significant, indicating a selective impairment in platelet function following infection. Biochemical markers did not show significant differences between groups. Further studies with larger cohorts and clinical efficacy assessments are essential to comprehensively evaluate the safety and effectiveness of transfusing PC from donors recently recovered from COVID-19.
