Diagnostic and prognostic utilities of multimarkers approach using procalcitonin, B-type natriuretic peptide, and neutrophil gelatinase-associated lipocalin in critically ill patients with suspected sepsis

Table 5 Comparison of NGAL and PCT at initial and follow-up measurements according to the in-hospital mortality

	Survivors (n = 96)		Non-survivors (n = 13)
	Initial measurement (mean ± SD)	Follow-up measurement (mean ± SD)	Initial measurement (mean ± SD)	Follow-up measurement (mean ± SD)
NGAL (ng/mL)	214.5 ± 249.1	148.7 ± 173.3^*	727.4 ± 554.5	775.7 ± 562.1
PCT (ng/mL)	5.56 ± 15.4	0.61 ± 2.18^†	31.8 ± 72.6	18.4 ± 37.4

^* P < 0.0001 vs. initial measurement.
^† P = 0.0012 vs. initial measurement.
Both initial and follow-up data were available in 109 patients (96 survivors and 13 non-survivors).
NGAL: neutrophil gelatinase-associated lipocalin; PCT: procalcitonin; SD: standard deviation.
