1. A biological fluid separation and testing system for a multi-component blood sample, comprising:

  • a biological fluid collection device, comprising;

    a lancet housing having an inlet port and an interior defining a first flow channel in fluid communication with the inlet port and a second flow channel in fluid communication with the first flow channel, wherein at least a portion of the second flow channel is diverted from the first flow channel;

    a puncturing element moveable between a pre-actuated position wherein the puncturing element is retained within the interior of the housing and a puncturing position wherein the puncturing element extends through the inlet port of the housing and provides fluid communication with the first flow channel; and

    a transfer cartridge having a reservoir, wherein the second flow channel is in fluid communication with the reservoir of the transfer cartridge; and

    a biological fluid separation device, comprising;

    a rotatable body having a center of rotation and an outer periphery, the rotatable body having a body inlet adapted to receive the multi-component blood sample;

    a separation chamber defined within the rotatable body and in fluid communication with the body inlet and having a chamber outlet spaced apart from the body inlet, the separation chamber adapted to receive the multi-component blood sample therein; and

    a blood component chamber defined within the rotatable body and in fluid communication with the chamber outlet, wherein when the separation chamber contains the multi-component blood sample and a rotational force is applied to the rotatable body, a blood component of the multi-component blood sample passes from the separation chamber into the blood component chamber and a second component of the multi-component blood sample is retained within the separation chamber,wherein the blood component chamber is disposed adjacent the center of rotation and the separation chamber is disposed adjacent the outer periphery of the rotatable body, andwherein the body inlet is engagable with the reservoir of the transfer cartridge for transferring the multi-component blood sample from the reservoir of the transfer cartridge to the biological fluid separation device.
