Abstract

Background: Vacuum tubes are widely used in the clinical laboratory for routine tests. We compared a newly developed Green Vac-Tube (SPM, Gimje, Korea) with Vacutainer (BD, Franklin Lakes, NJ, USA) and Vacuette (Greiner Bio-One, Frickenhausen, Germany) in routine chemistry and hematology tests.
Methods: A total of 101 volunteers, 81 patients and 20 healthy volunteer, were recruited and we had collected blood samples with three kinds of EDTA tubes and those of serum separating tubes. The samples were evaluated for chemistry and hematology tests using TOSHIBA 200FR (Toshiba, Tokyo, Japan) and ADVIA (Siemens, Deerfield, IL, USA) respectively. Their results were statistically analyzed by paired t-test and Bland-Altman plot.
Results: Their clinical utilities were examined by CLIA’88 programs. Paired t-test analysis revealed that the results of ALP, AST, total bilirubin, CO2, Hct and MCV showed statistically significant differences between Green Vac-Tube and previously used two vacuum tubes. Similar significant differences were also observed between previous two vacuum tubes. And 194 (4.37%) cases among 5,151 cases were in the critical region by Bland-Altman plot. All different cases, except Na+, K+ however, were clinically acceptable by CLIA’88 programs.
Conclusion: Green Vac-tube has good analytical performance compared to previously-used tubes.
