1. A puncturing system for generating a puncture wound for obtaining a sample of a body fluid from a tissue site, comprising:

  • a housing including a tissue interface surface configured to be pressed relative to the tissue site;

    a penetrating member positioned in the housing;

    a trigger coupled to the penetrating member, the trigger launching the penetrating member to pierce the tissue site resulting in a flow of body fluid upon an occurrence of an event;

    a body fluid testing member configured to determine at least one test parameter on which a body fluid obtaining probability depends;

    a release device with a locked state and a trigger state, the locked state preventing the trigger from being actuated, the trigger state releasing the trigger to provide for launch of the penetrating member through the tissue site; and

    a notification device that provides notification of a transition of the release device from the locked state to the trigger state.
