The authors examined both hard and soft glass evacuated blood-drawing tubes for possible effects on clinical chemistry measurements. Using routine laboratory procedures, no clinically or statistically significant difference could be detected in 34 analytes using 66 different methods. A special high-precision study utilizing an adaption of the NBS round-robin procedures for calcium, magnesium, sodium, and potassium detected no difference between paired sera when drawn or stored for 72 hours, or both, in the two types of glass. The authors conclude that the type of glass used in production of the evacuated blood-drawing tubes does not affect the clinical chemistry results obtained.
作者研究了硬质和软质玻璃真空采血管对临床化学检测结果可能产生的影响。采用常规实验室程序，使用66种不同方法检测34种分析物时，未发现临床上或统计学上的显著差异。一项特殊的高精度研究采用了美国国家标准局（NBS）钙、镁、钠和钾的循环检验程序的改进方法，结果显示，在两种类型的玻璃管中采集或储存72小时或两者兼有时，配对血清之间没有差异。作者得出结论，真空采血管生产中使用的玻璃类型不会影响所获得的临床化学检测结果。
