- Abstract
- Introduction: Nucleated red blood cell (NRBC) count is closely associated with the prognosis of neonates. The analysis of NRBC has traditionally been measured manually. Recently, a newly developed automated hematology analyzer, the UniCel DxH 800 (DxH 800), was released. The goal of our study was to evaluate the performance of the DxH 800 NRBC method in neonates with the reference manual method and against previous generation hematology analyzers. Methods: NRBCs were counted in 162 neonatal blood samples using the DxH 800, LH 750, and ADVIA 2120 vs. the reference manual technique. The concordance rate, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were obtained. Results: The DxH 800 showed an R-2 value of 0.945 and the concordance rate of 93.8%. Further assessment revealed 85.3% sensitivity, 96.1% specificity, 85.3% PPV, and 96.1% NPV, resulting in the highest area under the curve (0.961). The LH 750 and ADIVA 2120 demonstrated R-2 values of 0.851 and 0.529, respectively. Conclusion: The results obtained indicate the UniCel DxH 800 to be an excellent test on neonatal blood and superior to the other analyzers. Therefore, the DxH 800 is an effective and highly sensitive system for the analysis of NRBCs on newborns.
