    a vacuum-sealed pre-sample reservoir fluidically coupleable to the first sterile needle, the vacuum-sealed pre-sample reservoirs configured and arranged for collecting and storing patient bodily fluid withdrawn from the bodily-fluid withdrawing device;

    a single diversion mechanism coupled to the first sterile needle, the second sterile needle and the pre-sample reservoir, the diversion mechanism configured to selectively establish fluid communication between the first sterile needle and the pre-sample reservoir and fluidically isolate the second sterile needle in a first configuration, and selectively establish fluid communication between the first sterile needle and the second sterile needle and fluidically isolate the pre-sample reservoir in a second configuration; and

    at least one vacuum-sealed sample vessel, each of the at least one vacuum-sealed sample vessels configured and arranged for collecting and storing patient bodily fluid withdrawn from the bodily-fluid withdrawing device, each of the at least one sample vessels containing a culture medium;
