Abstract
A blood collection assembly includes an evacuated container having an open end with a puncturable stopper therein. A liquid impermeable receptacle in the container contains an additive and is removably immobilized in the stopper. In a method for preparing a blood sample for analysis, the stopper is punctured by a cannula connected to a blood supply. The cannula is then advanced until it contacts and dislodges the receptacle from the stopper causing the additive to be released directly into the container where it mixes with incoming blood.
