Although the automatic blood agitation machine was used for years in Thailand, there is no report about its efficacy. Therefore, a retrospective analytic study to analyze the risk of hemolysis in using automatic blood agitation machine was performed. A total of 14,682 blood  specimens sent to Clinical Chemistry Unit, Division of Laboratory Medicine, King Chulalongkorn  Memorial Hospital during the year 1998 was studied. The results revealed that the automatic agitation increased the risk of hemolysis (Odds ratio = 6.18, 95% Confidence interval = 4.27 - 8.93). Therefore, suggestion to use manual mixing is recommended.
