Value of Serum Cholinesterase Activity in the Diagnosis of Septic Shock Due to Bacterial Infections.

Background: We aimed to investigate whether serum cholinesterase (SChE) activity can be helpful for the diagnosis of septic shock and to evaluate its usefulness in comparison with procalcitonin (PCT) and C-reactive protein (CRP).

Methods: A prospective single-blinded study conducted in an intensive care unit of university hospital. Patients were classified as having cardiogenic shock, septic shock, or hemorrhagic shock.
