1. A blood sampling transfer device adapted to receive a blood sample having a cellular portion and a plasma portion, the blood sampling transfer device comprising:

  • a first component comprising at least two electrically driven internal miniature pumps; and

    a second component removably connected to the first component, the second component comprising;

    an inlet port,a flow channel,an outlet port, the inlet port and the outlet port in fluid communication via the flow channel,a filter disposed within the flow channel between the inlet port and the outlet port,a first chamber defined between the inlet port and the filter, anda transfer chamber defined between the filter and the outlet port;

    wherein the inlet port receives the blood sample upon actuation of the at least two electrically driven internal miniature pumps, and wherein the filter traps the cellular portion and allows the plasma portion to pass through the filter and into the transfer chamber; and

    wherein the at least two electrically driven internal miniature pumps are connected to one another via the first chamber to oscillate the blood sample back and forth over the filter, in which one electrically driven internal miniature pump is connected to a first side of the first chamber and another electrically driven internal miniature pump is connected to a second opposing side of the first chamber such that the filter is disposed between the one electrically driven internal miniature pump and the another electrically driven internal miniature pump.
