A system for collecting a whole blood sample includes a fill port (32), a metering chamber (72), a gasket or seal (16) and a reservoir (74). The gasket or seal (16) is positioned to a fill position, and a sample of whole blood is received in the metering chamber (72) until the metering chamber (72) is full. Then the seal (16) is moved to a closed position, thereby moving blood from the metering chamber (72) to the reservoir (74) and also sealing the reservoir (74). The seal (16), metering chamber (72) and fill port (32) together define a passageway at least a portion of which is coated with an anticoagulant. A diluting liquid contained in the reservoir (74) is mixed with the whole blood to dilute and stabilize the whole blood in the reservoir (74) for later analysis of one or more selected blood components. |
