Pre-analytical variables account for most laboratory errors and many factors affect the results from a patient. Type of tubes facilitated rapid separation and prevented hemolysis upon prolonged storage. However, there were some limitations associated with vacutainer conditions. To circumvent the problems, the comparability of complete blood cell count values was examined using various vacutainers. The results of the analysis showed a large coefficient variation of 0.24, 0.21 in the value of white blood cells and platelets, and significant correlation was observed between white blood cells, platelets, and the value of red blood cells (p<0.01). In each of the three tubes, compared to the value of platelets, white blood cells, the greatest coefficient variation was 0.27, 0.21. In correlation of the three companies, significant difference was observed in values of white blood cells, platelets, and platelet distribution width (p<0.01), however G and B, the value of platelets, and platelet distribution width were significantly lower (p<0.05). In conclusion, analysis of vacutainers showed that they were suitable for stability of these analytes under vacutainer conditions.
