Comparison of Sekisui Trank Insepack and BD Vacutainer Plastic Citrate Tubes for Routine Coagulation Assays / 임상검사와정도관리

ABSTRACT

BACKGROUND Coagulation assays can be easily affected by preanalytical variables, including the factors associated with the blood collection tube. Recently the Sekisui Trank Insepack (Sekisui Chemical Co., Ltd, Osaka, Japan; Insepack) blood collection tubes were introduced into Korea. The aim of this study was to compare the results of routine coagulation assays using the Insepack with those using BD Vacutainer (BD, Franklin Lakes, NJ, USA; Vacutainer) tubes, which are most widely used in Korea. METHODS: Paired blood samples from 64 patients were drawn into Insepack and Vacutainer 3.2% citrate tubes. The results of prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen, and fibrin/fibrinogen degradation product (FDP) were determined in parallel. RESULTS: No statistically significant differences were observed between Insepack and Vacutainer tubes for PT, fibrinogen, and FDP tests. For APTT which showed the significant differences between the results in the two tubes the mean difference was small (0.8 seconds), and it was not considered clinically significant. CONCLUSIONS: The results of this study suggest that Insepack tubes can be used in place of Vacutainer tubes for routine coagulation assays.
