Biological fluid sampling transfer device and biological fluid separation and testing system

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

• a biological fluid sampling transfer device adapted to receive the blood sample, the biological fluid sampling transfer device comprising:
• a housing having a resiliently deformable upper portion, a lower portion removably connectable to the upper portion, the lower portion having an inlet port, an outlet port, and a flow channel, the inlet port and the outlet port in fluid communication via the flow channel, the flow channel adapted to receive the blood sample via the inlet port, the upper portion transitionable between an undeformed position and a deformed position;
• and
• a puncturing element, a portion of which is disposed within the housing and adapted for movement between a pre-actuated position wherein the puncturing element is retained within the housing and a puncturing position wherein the puncturing element extends through the inlet port of the lower portion of the housing,
• wherein actuation of the upper portion from the undeformed position to the deformed position moves the puncturing element from the pre-actuated position to the puncturing position, and
• wherein after the puncturing element moves to the puncturing position, the upper portion returns to the undeformed position and the puncturing element returns to the pre-actuated position;
• and
• a blood testing device having a receiving port adapted to receive the outlet port of the lower portion of the housing of the biological fluid sampling transfer device for closed transfer of a portion of the blood sample from the biological fluid sampling transfer device to the blood testing device via the outlet port.
