1. An apparatus, comprising:
a distribution member forming at least a portion of a pre-sample reservoir and defining a first fluid flow path in fluid communication with a first outlet and a second fluid flow path in fluid communication with a second outlet; and
a flow controller in fluid communication with the distribution member, the flow controller having:
a first configuration to transfer a pre-sample volume of bodily-fluid from a patient to the pre-sample reservoir,
a second configuration to transfer a first volume of bodily-fluid to the first fluid flow path while bypassing the pre-sample volume of bodily-fluid contained in the pre-sample reservoir, and
a third configuration to transfer a second volume of bodily-fluid to the second fluid flow path while bypassing the pre-sample volume of bodily-fluid contained in the pre-sample reservoir,
the flow controller configured to transition from the first configuration to one of the second configuration or the third configuration after the pre-sample volume of bodily-fluid is transferred into the pre-sample reservoir, wherein the pre-sample volume of bodily-fluid in the pre-sample reservoir includes dermally-residing contaminants and the first volume of bodily-fluid and the second volume of bodily-fluid transferred to the first fluid flow path and second fluid flow path, respectively, are substantially free from dermally-residing contaminants, and
the distribution member configured to be coupled to at least one of a first sample reservoir after the first volume of bodily-fluid is transferred into the first fluid flow path or a second sample reservoir after the second volume of bodily-fluid is transferred into the second fluid flow path such that:
when the distribution member is coupled to the first sample reservoir, the first outlet places the first fluid flow path in fluid communication with the first sample reservoir to transfer a first sample volume of bodily-fluid into the first sample reservoir, and
when the distribution member is coupled to the second sample reservoir the second outlet places the second fluid flow path in fluid communication with the second sample reservoir to transfer a second sample volume of bodily-fluid into the second sample reservoir.
