OBJECTIVES Several previous studies have described the effects of interfering substances on clinical assay results; however, the effects of exogenous substances, particularly additives from blood collection tubes on quality control (QC) specimens and serum specimens have not been well examined. This study examines the effects of blood-collection tube additives on total triiodothyronine (TT3), and thyroxine (TT4), cortisol, and routine clinical chemistry tests in QC and serum specimens from apparently healthy volunteers. METHODS QC and serum specimens were poured or collected into different blood collection tubes. TT3 and TT4, cortisol, and routine chemistry tests were analyzed from the different blood-collection tube types. RESULTS The findings of this study demonstrate statistically and/or clinically significant blood collection tube-related alterations in the TT3, TT4, and cortisol concentrations of QC specimens and TT4 concentrations from serum specimens. CONCLUSIONS These findings have important implications for clinical laboratories, demonstrating that QC specimens should ideally, like patients' specimens, be poured into blood collection tubes. This strategy would reveal any adverse effects caused by blood collection tubes, which otherwise would not likely be detected by most routine QC practices. The results of this study also show the importance of producing blood collection tubes that contain additives that are truly inert and do not adversely affect clinical laboratory testing.

质量控制材料和血清样本中分析物浓度的与采血管相关的变化。

目的 先前的几项研究已经描述了干扰物质对临床检测结果的影响。然而,外源性物质,特别是来自采血管的添加剂对质量控制 (QC) 标本和血清标本的影响尚未得到很好的研究。本研究检查了采血管添加剂对总三碘甲腺原氨酸 (TT3) 和甲状腺素 (TT4)、皮质醇以及 QC 和明显健康志愿者的血清样本中的常规临床化学测试的影响。方法将QC和血清标本倒入或收集到不同的采血管中。从不同的采血管类型中分析了 TT3 和 TT4、皮质醇和常规化学测试。结果 本研究的结果证明了 QC 标本的 TT3、TT4 和皮质醇浓度以及血清标本的 TT4 浓度在统计学和/或临床上显着的采血管相关变化。结论 这些发现对临床实验室具有重要意义,表明理想情况下 QC 标本应像患者标本一样倒入采血管中。该策略将揭示由采血管引起的任何不利影响,否则大多数常规 QC 实践不可能检测到这些不利影响。这项研究的结果还表明,生产含有真正惰性且不会对临床实验室测试产生不利影响的添加剂的采血管的重要性。QC 标本的皮质醇浓度和血清标本的 TT4 浓度。结论 这些发现对临床实验室具有重要意义,表明理想情况下 QC 标本应像患者标本一样倒入采血管中。该策略将揭示由采血管引起的任何不利影响,否则大多数常规 QC 实践不可能检测到这些不利影响。这项研究的结果还表明,生产含有真正惰性且不会对临床实验室测试产生不利影响的添加剂的采血管的重要性。QC 标本的皮质醇浓度和血清标本的 TT4 浓度。结论 这些发现对临床实验室具有重要意义,表明理想情况下 QC 标本应像患者标本一样倒入采血管中。该策略将揭示由采血管引起的任何不利影响,否则大多数常规 QC 实践不可能检测到这些不利影响。这项研究的结果还表明,生产含有真正惰性且不会对临床实验室测试产生不利影响的添加剂的采血管的重要性。倒入采血管。该策略将揭示由采血管引起的任何不利影响,否则大多数常规 QC 实践不可能检测到这些不利影响。这项研究的结果还表明,生产含有真正惰性且不会对临床实验室测试产生不利影响的添加剂的采血管的重要性。倒入采血管。该策略将揭示由采血管引起的任何不利影响,否则大多数常规 QC 实践不可能检测到这些不利影响。这项研究的结果还表明,生产含有真正惰性且不会对临床实验室测试产生不利影响的添加剂的采血管的重要性。
