Abstract: A blood separation device that allows high quality plasma to be generated using a single power source. The device includes a housing with an inlet port adapted to receive the blood sample, a first chamber having a first chamber flow channel in fluid communication with the inlet port, a second chamber having a second chamber flow channel, a separation member disposed between the first chamber and the second chamber. In some embodiments, the blood separation device detects or tests for the presence of a substance, such as an antigen or an antibody.

Abstract: A filtration cell (10) for a biological sample having an outer housing (12) defining a first chamber and an inner housing (14) defining a second chamber is disclosed. The inner housing is disposed within the first chamber and rotatable with respect to the outer housing and at least a portion of the inner housing includes a filtration membrane (52). Upon rotation of the inner housing, a first portion of the biological sample passes from the first chamber into the second chamber and a second portion of the biological sample is restrained in the first chamber. Alternatively, the filtration cell may also include a rotation element disposed in the inner housing. Upon rotation of the rotation element with respect to the inner housing, a first portion of the biological sample to passes from the second chamber into the first chamber and a second portion of the biological sample is restrained in the second chamber.
