Abstract
A blood collection assembly includes an evacuated container having an open end with a puncturable stopper therein. A receptacle in the container contains an additive and has an open end covered by a puncturable, non-resealable material. In a method for preparing a blood sample for analysis, the stopper and receptacle covering are punctured by a cannula, the cannula is partially retracted into the receptacle so that blood drawn through the cannula contacts the additive and washes it directly into the container through a hole in the covering made by the cannula.
