In Critically Ill Patients, Serum Procalcitonin Is More Useful in Differentiating between Sepsis and SIRS than CRP, Il-6, or LBP

Table 3

Test results using the highest value of the biomarkers within the first 24 hours of admission on the ICU.

		Sepsis	No sepsis	All
CRP (cut-off value 50 μg/mL)	Test +	28	34	62
	Test −	4	10	14
PCT (cut-off value 2 ng/mL)	Test +	31	9	40
	Test −	1	35	36
PCT (cut-off value 10 ng/mL)	Test +	21	3	24
	Test −	11	41	52
IL-6 (cut-off value 50 pg/mL)	Test +	29	26	55
	Test −	3	18	21
LBP (cut-off value 30 μg/mL)	Test +	17	4	21
	Test −	15	40	55
All patients		32	44	76

Test +: number of patients with marker-level equal or above cut-off value.
Test −: number of patients with marker-level below cut-off value.
