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