1. An apparatus, comprising:

  • a transfer adapter including a proximal end portion and a distal end portion and defining an inner volume therebetween, the distal end portion including a port configured to be fluidically coupled to a diversion device in fluid communication with a bodily-fluid of a patient and configured to divert a first volume of bodily-fluid containing contaminants, the transfer adapter configured to receive a second volume of bodily-fluid from the diversion device, the diversion device configured to prevent the second volume of bodily-fluid from flowing to the transfer adapter prior to diverting the first volume of bodily-fluid such that the second volume of bodily-fluid is substantially free of contaminants;

    a fluid reservoir including a contact surface and configured to be inserted though the proximal end portion of the transfer adapter such that at least a portion of the fluid reservoir is movably disposed within the inner volume from a first position to a second position;

    a disinfection member configured to couple to the transfer adapter and to establish contact with the contact surface of the fluid reservoir to disinfect the contact surface when the fluid reservoir is in the first position; and

    a puncture member disposed within the inner volume of the transfer adapter and fluidically coupled to the port, the puncture member configured to couple with the contact surface of the fluid reservoir to establish fluid communication with the fluid reservoir after the disinfection member disinfects the contact surface and after the fluid reservoir is moved from the first position toward the second position,whereby diverting the first volume of bodily-fluid and disinfecting the contact surface collectively reduce contamination that can result in false results in culture tests of the second volume of bodily-fluid.
