1. A body fluid sampling system for use on a tissue site, the system comprising:

  • a controllable drive force generator;

    a plurality of penetrating members operatively coupled to said controllable drive force generator, said controllable drive force generator moving each of said members along a path out of a housing having a penetrating member exit into said tissue site, stopping in said tissue site, and withdrawing out of said tissue site each of a penetrating member at least partially positioned adjacent to an analyte detecting member in a sample chamber, each sample chamber configured to receive body fluid from a wound in tissue created by a penetrating member, and each analyte detecting member configured to determine at least one analyte level using a body fluid sample of less than about 1 microliter;

    a support member with a surface that carries said penetrating members, said support member being movable to move each of said penetrating members to a launch position associated with said force generator; and

    said controllable drive force generator configured to provide a controllable velocity trajectory into the tissue and out of said tissue.
