Marked serum procalcitonin level in response to isolated anaphylactic shock.

The objective of this study was to present a case report that highlights the limitation of serum procalcitonin levels greater than 10 ng/mL as being almost exclusively secondary to septic shock. Data source was a medical intensive care unit patient at the University of Louisville. Anaphylactic shock may cause elevations of serum procalcitonin to levels greater than 10 ng/mL.
