1. A cartridge for a fluid sampling device for collecting a fluid sample from a test subject, including:

  • a pump being moveable in a first direction to draw fluid into the pump and a second direction to expel fluid from the pump;

    a reservoir in fluid communication with the pump;

    a first conduit fluidly connecting the reservoir to a first fluid fitting configured to fluidly connect the cartridge to a tubing having a distal end inserted into the subject;

    a second conduit fluidly connecting the reservoir to a second fluid fitting configured to connect the cartridge to a sample collection component; and

    a third conduit fluidly connecting the reservoir to a third fluid fitting configured to connect the cartridge to a sterile fluid supply;

    wherein the pump is configured to move in the first direction and second direction in response to movement of a portion of the fluid sampling device when the cartridge is operably connected to the fluid sample device and the fluid conduits are configured such that when the cartridge is operably connected to the fluid sampling device, a first valve of the fluid sampling device controls fluid flow in the first fluid conduit, a second valve of the fluid sampling device controls fluid flow in the second fluid conduit, and a third valve of the fluid sampling device controls fluid flow in the third fluid conduit;

    wherein the cartridge includes at least one window through a frame configured to allow the first valve of the fluid sampling device to extend through the frame to control fluid flow in the first fluid conduit by applying compressive force to the first fluid conduit, the second valve of the fluid sampling device to extend through the frame to control fluid flow in the second fluid conduit by applying compressive force to the second fluid conduit, and the third valve of the fluid sampling device to extend through the frame to control fluid flow in the third fluid conduit by applying compressive force to the third fluid conduit, andwherein the pump, reservoir, and fluid conduits are secured to the frame configured to be removably attached to the first valve, the second valve, and the third valve of the fluid sampling device.
