手工计数法与血细胞分析仪测定血小板的比较

Comparison of manual counting method and blood cell analyzer in determination of platelet

目的评价Dinana-5型全自动血细胞分析仪对血小板测定的临床应用价值。方法使用血细胞分析仪和显微镜,严格按规定操作检测标本得出结果。结果血小板数〈20×10^9/L,和〈50×109/L,及〉400×109/L时两种计数方法差异均有统计学意义（P〉0.05）;当血小板数为（50~100）×10^9/L时,（100~300）×10^9/L,（300~400）×10^9/L时两种方法间无统计学意义（P〉0.05）。结论血细胞分析仪对血小板计数明显降低及明显增多时,应用手工法计做重复检测,提高结果准确性。

Objective To study the clinical value of detecting platelet by using Dinana- 5 automatic blood cell analyzer. Methods Using blood cell analyzer and microscope detect the number of platelet in strict accordance with the provisions of the operation. Results When Platelet number was less than 20 × 109/ L,less than 50 × 10^9/ L and more than 400 × 109/ L,the differences of the two methods were statistically significant（ P〉0. 05）. When the platelet number was between 50 and 100 × 10^9/ L,or 100- 300 × 10^9/ L,the differences of the two methods had no statistical significance（ P〉0. 05）. Conclusions When the blood cell analyzer for platelet count was significantly decreased or increased,the application of manual method can improve the accuracy of results.
