A collaborative study involving 20 clinical laboratories representing diverse geographical regions was organized to examine the microbiology of evacuated blooc collection tubes. Overall, 14% of the 1433 tubes examined contained microorganisms representing a variety of bacteria and fungi. Of note was the finding that nearly 9% of tubes with yellow closures, which are stated to be sterile by the manufacturers, contained bacteria, including Pseudomonas aeruginosa, enterococci, Serratia marcescens, and Acinetobacter calcoaceticus. Sterilization of these potential sources of infection is advisable.
一项涉及来自不同地理区域的20个临床实验室的合作研究组织起来，以检查真空采血管的微生物学情况。总体而言，在检查的1433支采血管中，14%含有代表各种细菌和真菌的微生物。值得注意的是，近9%带有黄色封盖的采血管（制造商称其为无菌）含有细菌，包括铜绿假单胞菌、肠球菌、黏质沙雷氏菌和醋酸钙不动杆菌。对这些潜在感染源进行灭菌是可取的。
