Diagnostic performance of Neutrophil CD64 index, procalcitonin, and C-reactive protein for early sepsis in hematological patients

Figure 1 Receiver-operating characteristic curves comparing the neutrophil CD64 index, procalcitonin and high-sensitivity C-reactive protein to predict early sepsis in hematological patients. hs-CRP: High-sensitivity C-reactive protein; nCD64: Neutrophil CD64; PCT: Procalcitonin.

Figure 3 The level of neutrophil CD64 index in patients with hematological diseases as a function of infection status. nCD64: Neutrophil CD64.

Figure 4 Test report for the neutrophil CD64 index. The neutrophil CD64 (nCD64) index is typically < 1.20 in healthy individuals. The majority of hospitalized patients without infection or sepsis have a nCD64 index value of 1.00-2.00. Every laboratory should establish their own (no infection) reference range. Clinical decisions based on the nCD64 index may vary by age and disease type. PMN: Neutrophil count; FITC: Fluorescein isothiocyanate; PE: Phycoerythrin.
