摘要

在5家医院的现场试验中对Becton-Dickinson VACUTAINER牌血清分离管(SST)进行了评价。SST真空抽血管含有半固态硅聚合物，在离心过程中迁移到血清-凝块界面，形成屏障，将血清与红细胞分离。对18项临床化学指标进行了研究。与常规抽血管相比，未观察到SST引起的临床显著变化。碳酸氢盐、钙、氯化物、胆固醇、葡萄糖(Beckman分析仪)和钠的含量变化有统计学意义(t检验，p=0.05)。每项试验(葡萄糖、尿酸等)数据分析2次;一次作为一个完整的集合，一次作为一个仅由异常数据组成的子集。在早期(2,3)临床试验中观察到的小的、统计学上显著的LDH偏倚不存在。

Field evaluation of the Becton-Dickinson SST.

The Becton-Dickinson VACUTAINER BRAND SERUM SEPARATOR TUBE (SST) was evaluated in a field test in five hospitals. The SST evacuated blood drawing tube contains a semi-solid silicon polymer which migrates to the serum-clot interface during centrifugation causing a barrier to form which separates serum from red cells. Eighteen clinical chemistry determinations were studied. No clinically significant SST induced changes were observed when compared to conventional blood drawing tubes. Statistically significant changes (t-test, p=0.05) were observed for bicarbonate, calcium, chloride, cholesterol, glucose (Beckman Analyzer), and sodium. For each test (glucose, uric acid, etc.) data were analyzed twice; once as a complete set, and once as a subset consisting of abnormal data only. The small, statistically significant LDH bias observed in the earlier (2,3) clinical trials was not present.
