The ELite 580 (Erba Lachema) Hematology Analyzer is a newly developed automated hematology analyzer that uses impedance and flow cytometry technologies. The analyzer provides 25 reportable parameters including a 5-part differential and additionally 4 research parameters with a throughput of 80 samples per hour. To evaluate the performance of the fully automated 5-part differential hematology analyzer ELite 580 as per the international standards and correlate the results with a reference analyser, LH 780 from Beckman Coulter. We evaluated the analyzer’s performance by determining background noise, carryover, precision, linearity and correlation of complete blood cell count parameters between the ELite 580 from Erba Lachema and the LH 780 from Beckman Coulter at a tertiary care hospital, according to the Clinical and Laboratory Standards Institute guidelines. The ELite 580 showed minimal background noise and carryover, high precision, accuracy and linearity over a wide analytical range for white blood cells, hemoglobin, red blood cells, hematocrit, and platelet parameters. Correlation between the ELite 580 and the LH 780 was good for all parameters (R² > 0.90) except for mean corpuscular hemoglobin concentration (MCHC) and the basophil count. ELite 580 Hematology Analyzer with its precise and accurate results and ease of operation is suitable for clinical use in medium to large sized hematology laboratories.

ELite 580 (Erba Lachema) 血液学分析仪是一种新开发的自动化血液学分析仪，采用阻抗和流式细胞术技术。该分析仪提供 25 个可报告参数，包括 5 部分差异和另外 4 个研究参数，吞吐量为每小时 80 个样本。根据国际标准评估全自动 5 分类血液学分析仪 ELite 580 的性能，并将结果与​​参考分析仪 Beckman Coulter 的 LH 780 相关联。我们通过确定三级医院 Erba Lachema 的 ELite 580 和 Beckman Coulter 的 LH 780 之间全血细胞计数参数的背景噪声、残留、精度、线性和相关性来评估分析仪的性能，根据临床和实验室标准协会指南。ELite 580 在白细胞、血红蛋白、红细胞、血细胞比容和血小板参数的广泛分析范围内显示出最小的背景噪音和残留、高精度、准确度和线性度。ELite 580 和 LH 780 之间的相关性对于所有参数都很好（R²  > 0.90) 除了平均红细胞血红蛋白浓度 (MCHC) 和嗜碱性粒细胞计数。ELite 580血液分析仪结果准确准确，操作简便，适合大中型血液实验室临床使用。
