1. A puncturing device for generating a puncture in a body part for sampling a body fluid, comprising:

  • a housing having a contact element adapted to be pressed against a body part;

    a sensor for detecting a test parameter;

    an analytical unit disposed in the housing and in communication with the sensor, the analytical unit determining whether the detected test parameter meets a test condition and initiating a waiting period that begins when the test parameter meets the test condition, the analytical unit determining whether to trigger the puncturing operation at the end of the waiting period; and

    a signaling unit that generates a user-recognizable optical, acoustic or vibratory signal indicating elapsed time of the waiting period;

    wherein the sensor monitors the test parameter during the waiting period and the analytical unit determines whether the test parameter falls within a predefined range during the waiting period, further wherein the analytical unit initiates the puncturing operation at the end of the waiting period if the test parameter falls within the predefined range during the waiting period.
