Diagnostic accuracy of sTREM-1 to identify infection in critically ill patients with systemic inflammatory response syndrome.

Objectives: To assess the accuracy of plasma levels of soluble Triggering Receptor Expressed on Myeloid cells (sTREM)-1 to diagnose infection in critical patients with systemic inflammatory response syndrome (SIRS).

Design And Methods: We prospectively studied 114 patients with SIRS criteria. The patients' plasma levels of sTREM-1 were measured within 24h of admission to the intensive care unit.
