Abstract
A device for separating plasma from whole blood is provided having an evacuated primary collection chamber capable of fluid communication through a porous filter to an evacuated secondary collection chamber. An agglutinating agent is provided within the primary collection chamber so as to aggregate blood cells within a whole blood sample. The porous filter has a pore size which is small enough to capture the aggregated blood cells therein, yet large enough to permit plasma to transfer therethrough under pressures associated with conventional evacuated blood collection tubes. The primary and secondary collection chambers may be provided in separate containers or tubes, with transfer occurring therebetween through a transfer device including the porous filter therein.
