摘要：

目的:探讨改良人工推片法在血小板计数减少标本复检中的应用。方法:采用常规人工推片法和改良人工推片法,分别对我院住院患者仪器测定血小板计数≤60×10⁹ L^-1的574例标本进行复检并分析。结果:574例标本中,检出血小板聚集阳性标本常规人工推片法为21例,改良人工推片法为24例,3例血小板大量聚集成团分布的标本不能用常规法而可以经改良法检出。结论:改良人工推片法可降低血小板大量聚集标本的漏检率。

Objective: To explore the application of improved manual blood smear in thrombocytopenia specimens. Methods: Using normal blood smear method and improved manual blood smear method, the 574 serum samples of inpatient whose platelet count are less than 60×10⁹ L^-1 were rechecked and analyzed. Results: In 574 samples,21 positive samples of platelet aggregation were detected by using normal blood smear method, while 24 cases were found by using improved method. Three cases with a great quantity of agminated platelet could not be checked by conventional method but could be done by improved one. Conclusion: Improved manual blood smear decrease the omission factor of samples of great platelet aggregation.
