OBJECTIVE
This study investigated the quality of trauma specimens by comparing line draws to venipuncture.
DESIGN
The draw type (line or venipuncture); container type (Vacutainer or Microtainer); and suitability for processing (processed/hemolyzed/clotted) of routinely collected trauma specimens was analyzed.
SETTING
The clinical laboratory of a Level I Pediatric Trauma Center.
MAIN OUTCOME MEASURE
Hemolyzed trauma specimens were analyzed according to method of collection, collector, and type of container to identify issues resulting in unusable samples.
RESULTS
The data shows that for 13% of all draws, portions of the results were affected by hemolysis. Sixteen percent of line draws and 6% of venipunctures were hemolyzed (p = 0.04). There was no statistical association with who collected the sample (p = 0.07) or type of container (p = 1.00).
CONCLUSION
Based on this sample of data, the laboratory recommends that, whenever possible, venipunctures be performed for laboratory testing of blood specimens to improve trauma specimen integrity.
目的
本研究通过比较动脉穿刺采血与静脉穿刺采血来调查创伤样本的质量。
设计
分析常规采集的创伤样本的采血类型（动脉穿刺或静脉穿刺）、容器类型（真空采血管或微量采血管）以及处理的适用性（已处理/溶血/凝血）。
地点
一级儿科创伤中心的临床实验室。
主要观察指标
根据采集方法、采集人员和容器类型对溶血的创伤样本进行分析，以确定导致样本不可用的问题。
结果
数据显示，在所有采血中，13% 的结果部分受到溶血影响。16% 的动脉穿刺采血样本和6% 的静脉穿刺采血样本发生溶血（p = 0.04）。样本采集人员（p = 0.07）或容器类型（p = 1.00）与溶血无统计学关联。
结论
基于该样本数据，实验室建议，只要有可能，应采用静脉穿刺采集血液样本进行实验室检测，以提高创伤样本的完整性。
