1. An apparatus, comprising:
a housing having an inlet configured to be placed in fluid communication with a bodily fluid source and an outlet configured be placed in fluid communication with a fluid collection device, the housing forming a sequestration portion configured to receive an initial volume of bodily fluid from the bodily fluid source; and
an actuator coupled to the housing, the actuator having a first configuration in which a first fluid flow path places the inlet in fluid communication with the sequestration portion and a second configuration in which a second fluid flow path places the inlet in fluid communication with the outlet, the actuator including a diaphragm coupled to at least one seal defining a portion of the first fluid flow path when the diaphragm is in a first state and defining a portion of the second fluid flow path when the diaphragm is in a second state, the diaphragm configured to transition from the first state to the second state when a negative pressure differential through a portion of the actuator is greater than a threshold amount of negative pressure,
wherein the fluid collection device is configured to be placed in fluid communication with the outlet to produce a negative pressure differential (1) within the first fluid flow path operable to draw the initial volume of bodily fluid into the sequestration portion when the actuator is in the first configuration, and (2) within the second fluid flow path operable to draw a sample volume of bodily fluid into the fluid collection device when the actuator is in the second configuration.
