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