Abstract
A blood separation device adapted to receive a blood sample having a whole blood portion and a plasma portion is disclosed. The blood separation device includes a housing defining a first chamber, a second chamber, and a separation member disposed therebetween. The blood separation device also includes an actuator, wherein actuation of the actuator draws the blood sample into the first chamber and the separation member is adapted to allow the plasma portion to pass through the separation member to the second chamber. The blood separation device matches the plasma chamber volume, the blood chamber volume, and the applied single pressure source so that the correct trans-membrane pressure and shear rate is obtained.
