Abstract:
A composition is provided for use, particularly in evacuated blood collection tubes, as a blood partitioning composition. The composition is useful in provididng cleaner serum or plasma samples for biochemical tests, including a wide range of drugs. The composition includes a balanced dual resin component which provides the desired hydrophobic property while simultaneously controlling viscosity and the specific gravity, which component is comprised of poly-alpha-pinene resin which provides good drug recovery but low density with a chlorinated hydrocarbon resin which provides the proper density level while maintaining the desired hydrophobic property of the resin blend. Thixotropic property is achieved by adding silica and network stabilizer in the composition.
