1. A fluidic circuit for processing fluid, comprising:
- a sample loading chamber for receiving an amount of fluid for processing, said sample loading chamber having a sample inlet port;
a sample pass through channel having a first end and a second end, said first end of said sample pass through channel in fluid communication with said sample loading chamber;
a separation chamber in fluid communication with said second end of said sample pass through channel;
a sample flow channel having a first and a second end, said first end of said sample flow channel in fluid communication with said sample pass through channel; and
an analysis chamber in fluid communication with said second end of said sample flow channel.

Abstract
A fluidic circuit for receiving a fluid and separating a component of a fluid from the fluid comprises a separation chamber for receiving the fluid, an air chamber in fluid communication with the separation chamber, and return channel in fluid communication with the separation chamber. In an advantageous embodiment, the fluidic circuit is subjected to a force, such as a centrifugal force, so that substantially all of the component of the fluid is moved to the return channel while substantially all remaining portions of the fluid are moved tot the separation chamber.
