Abstract
A multi-layer plasma separation card comprising (a) a first layer including a sample receiving member comprising (i) a top planar surface for applying or receiving a blood sample, said sample receiving portion being adapted to permit contact of said blood sample with a separating member; and (ii) a bottom planar surface being adapted to contact said separating member, (b) a second layer including at least three separating members, each separating member being adapted to permit the passage of plasma to an absorptive member and comprising (i) a top planar surface for receiving said blood sample; and (ii) a bottom planar shield-shaped surface being adapted to contact said absorptive member, and (c) a third layer including at least two absorptive members for absorbing plasma from the bottom planar surface of each corresponding separating member and a backing member arranged in a manner to support said absorptive members, each absorptive member comprising a removable absorptive element having a top planar surface being adapted to contact said bottom planar surface of the separating member, said absorptive element is detachable fixed to the third layer.
