1. An apparatus for obtaining a bodily fluid sample from a patient, the apparatus comprising:

  • a pre-sample reservoir configured to receive a first volume of bodily-fluid withdrawn from the patient;

    a diverter including an inlet port, a first outlet port, and a second outlet port, the inlet port configured to be coupled to a lumen-defining device for receiving bodily-fluids from the patient, the first outlet port configured to couple to a first sample reservoir and the second outlet port configured to couple to a second sample reservoir, the diverter defining a first fluid flow path configured to place the pre-sample reservoir in fluid communication with the inlet port and a second fluid flow path configured to place the first outlet port and the second outlet port in fluid communication with the inlet port, the first fluid flow path configured to be fluidically isolated when the second fluid flow path is placed in fluid communication with the inlet port such that contaminants in the first volume of bodily-fluid are sequestered in the pre-sample reservoir;

    a first movable member movably coupleable to the diverter and configured to be moved through the first outlet port between a first configuration, in which the first sample reservoir is sequestered from the first outlet port and the second fluid flow path, and a second configuration, in which the first movable member places the first sample reservoir in fluid communication with the second fluid flow path, the second fluid flow path configured to be substantially unobstructed when the first movable member is in the first configuration and when the first movable member is in the second configuration; and

    a second movable member movably coupleable to the diverter and configured to be moved through the second outlet port between a first configuration, in which the second sample reservoir is sequestered from the second outlet port and the second fluid flow path, and a second configuration, in which the second movable member places the second sample reservoir in fluid communication with the second fluid flow path, the second fluid flow path configured to be substantially unobstructed when the second movable member is in the first configuration and when the second movable member is in the second configuration.
