Reducing adult phlebotomy blood loss with the use of pediatric-sized blood collection tubes.

Author information

Department of Pathology, Beth Israel Hospital, Boston, Massachusetts.


The feasibility of collecting smaller blood volumes during phlebotomy for diagnostic laboratory testing was evaluated by substituting pediatric-size for adult-size blood collection tubes. The volume of blood drawn with the use of pediatric-size tubes from 41 patients in an intensive care unit (120.2 mL total; 32.2 mL/day) was 46.8% lower than in that of a control population for which adult-size tubes were used (226.1 mL total; 55.6 mL/day). Sufficient blood was available for performance of all laboratory tests ordered at the time of the phlebotomy. Although substituting pediatric-size tubes does not address the problem of excessive use of laboratory tests, smaller tubes may reduce the severity of phlebotomy-induced anemia in adults without compromising laboratory test procedures.
