Abstract
A process for separating and recovering serum and plasma components from a whole blood sample including passing a whole blood sample through a separating filter formed of a blood cell separating layer composed mainly of fibers impregnated with a coating agent. A device includes a blood collector having a needle at one end and a blood suction means at the other end, and a separating filter including a blood cell separating layer, the filter being provided in the intermediate zone of the blood collector, whereby a whole blood sample sucked through the needle by depressurizing the blood suction means is passed through the separating filter.
