體液細胞分析方法相關性比較

本研究是利用Sysmex XE-5000全自動血球分析儀，評估中山醫大附設醫院的體液檢查品質。最新一代的Sysmex XE-5000搭配第一代研發的分析體液偵測軟硬體，針對55支檢體的相關性分析，其中包括有核細胞及白血球、紅血球、白血球分類等數據，並與人工細胞計算盤，利用鏡檢計數的結果進行比較。經由Pearson相關係數統計，針對兩種實驗方法中，對於白血球與全部有核細胞所分析得到的相關性為0.9868，而白血球與白血球相關性為0.9851，呈現有較好的相關性；經由Pearson相關係數統計分析發現，兩種實驗方法中紅血球相關性為0.9973，因此具備良好的相關性；經由各實驗方法的白血球分類檢測所得相關係數統計，並將儀器與人工的的報告模式互相進行轉換分析，獲得的平均PMN％相關性為0.9114，平均MN％相關性為0.8829，顯示兩者間也具有好的相關性結果。

Body fluid analysis using Sysmex XE-5000 series automated hematology analyzer was evaluated and the acquired data was used to compare with previous manual methods. A total of 55 specimens were collected and their total nucleated cell, WBC counts, RBC counts and differential counts were measured in this evaluation. Among them, five specimens were excluded from this examination due to its presence of clots, and error messages displayed on white blood cell and red blood cell parameters. Pearson correlation coefficients for WBC/WBC parameters between two methods were applied in the analysis and a coefficient of 0.9851 was determined. A coefficient of 0.9868 was also calculated from WBC/TNC parameter collected from two methods. The correlation coefficients for differential counts of both PMN and MN were 0.9111 and 0.8829, respectively. These data suggested that a very good correlation was achieved based on the applications of these two different techniques.
