ABSTRACT:
A method is disclosed for isolating blood serum from clotted whole blood and for isolating blood plasma from mixtures of whole blood with anti-coagulants. The method comprises partially sinking an apparatus of the invention in the appropriate blood specimen, conveniently with the assistance of centrifugation.
The apparatus of the invention comprises a hollow elongate body open at both ends. One end is partially closed with a filter member which prevents the passage of solid phase components of clotted whole blood and solid phase components of mixtures of blood with anti-coagulants but allows passage of blood serum or blood plasma.
