ABSTRACT:
A fluid which comprises an olefin-terminated polyester an unmodified polyester and a polymerized .alpha.-olefin is provided which facilitates the separation of blood into light and heavy phases via centrifugation in a blood collection vessel. The fluid is useful as a component of a partitioning composition formulated to have appropriate specific gravity to be positioned intermediate the light and heavy blood phases during centrifugation. A partitioning composition including a fluid of the invention provides a particular advantage in blood collection vessels used in therapeutic drug monitoring, due to the relatively low affinity between the fluid component of the composition and commonly monitored classes of drugs.
