Abstract
A blood collection assembly includes a tube, which may be evacuated, and an insert therein. The insert is descendably affixed to the tube wall and, after separating a blood sample taken in the tube into solid and liquid phases, descends during centrifugation and comes to rest at the solid-liquid interface on a projection from the tube bottom. An interior surface of the assembly may be modified to render it clot activating. The invention includes a method for preparing a blood sample for analysis using the assembly.
