Content Description: This course discusses sepsis and the laboratory tests used to detect and intervene in its progression to severe sepsis and septic shock. It covers the usefulness and limitations of C-reactive protein, procalcitonin, and lactic acid concentration. Novel biomarkers that may prove useful as methods for early detection of severe sepsis in the near future are also discussed.
