AbstractThis study was set in the Division of Laboratory Medicine, Chulalongkorn Hospital. All 2,000 blood specimens were randomly collected using evacuated blood collection by plain or gel vacuum tubes. After collection, each specimen was considered and judged using criteria of speci men rejection to determine how proper the specimen presentations were. All data were reviewed, collected and interpreted. It revealed that there were only 20 (1%) improper specimens and all were improper in quality. There was no significant difference between the ratio of improper specimens in both groups (P > 0.30). From this study, it revealed that efficacy of both types of vacuum tubes was not different. The new gel vacuum tube seems to be an effective tool in the evacuated blood collection system due to its advantage in reduction of time in specimen process ing.
