However the reliability of these measures may be jeopardized by the effects of therapy. Moreover in critical illness what is normal is not necessarily optimal. Procalcitonin a putative marker of occult infection is emerging as a valuable diagnostic marker in the ICU. Although questions remain regarding its specificity an increasing body of work suggests that it is reliably elevated in the setting of infection. As demonstrated by Level and colleagues in this issue of Critical Care its utility as a diagnostic marker is not affected by concomitant hemodialysis. Keywords continuous venovenous hemodialysis critical illness intensive care unit measure procalcitonin Measurement is the currency of critical care. Illness in the intensive care unit is defined not by pathologic changes in a particular tissue or by structural changes in a specific organ but by a constellation of quantifiable changes in physiological and biochemical measures. To round in an intensive care unit is to be exposed to a cacophony of numbers - the pH the Glasgow Coma Scale the fibrinogen level. To be an intensivist means to take this chaotic melange of digits and to transform them into a clinical profile that will support a therapeutic decision. An uninitiated visitor to a contemporary intensive care unit could be forgiven for .
