[Evaluation of neutrophilic CD64 index as a diagnostic marker of bacterial infection in blood diseases].

This study was aimed to investigate the value of neutrophilic CD64 index (nCD64 index) as a diagnostic marker of bacterial infection in hematologic diseases. Experimental data of 232 patients with hematologic diseases were analyzed retrospectively. The nCD64 index was detected by flow cytometry and was compared with the levels of erythrocyte sedimentation rate (ESR), C reaction protein (CRP) and fibrinogen respectively.
