ALB and acute kidney injury: Patients in the group with ALB above the optimal cut-off value (33.45 g/L or 27.85 g/L) had lower mortality, faster decline in inflammatory markers, and decreased incidence of septic shock and AKI, so we suggest that 33.45 g/L as the ALB infusion target within 14 days and 27.85 g/L as the ALB infusion target on day 7 after admission.
