血小板释放是一个常见的生理过程，即血小板活化后，不断释放各种颗粒和内容物，最后达到血浆。目前，我国已经逐渐重视对抗血小板药物的研究，尤其是在颗粒释放机制、标本检验前变异等方面的关注更高。当其在体外时，血小板的释放则和标本检验前变异存在密切的相关性，血小板形态改变与储血容器材质、剪切刀、内部添加剂、保存温度等都有关，受其影响，标本检验前则会出现变异表现，检验的结果也会出现异常。鉴于此，本文将主要针对血小板进行全面的分析和研究，并了解其颗粒释放机制与标本检验前变异方面的关系，旨在使检验的准确率得以提升。

目的探究检验前质量控制在生化检测中的应用。方法以生化检测标本100例为对象，参照组50例采用常规管理，研究组50例采用质量控制，对比检验质量，进行统计学分析。结果研究组检验正确率明显高于参照组，P<0.05，统计学意义存在。结论生化检验采用检验前质量控制，有效提高检验准确率，有助于疾病的治疗。
abstract: objective to explore the application of quality control in biochemical testing before testing. Methods 100 biochemical samples were taken as the object,50 in the reference group were routinely managed,50 in the study group were controlled by quality control, and the quality was compared and analyzed statistically. Results The correct rate of the study group was significantly higher than that of the reference group, P <0.05, which was statistically significant. Conclusion The quality control of biochemical test can improve the accuracy and help to treat the disease.
