A body fluid sampling system is provided for use on a tissue site. In one embodiment, the system (10) comprises a cartridge (12); a penetrating member driver 34; a plurality of penetrating members (18) arranged in a radial configuration on the cartridge (12) such that sharpened distal tips of the penetrating members (18) point radially outward. An active one of the penetrating members may be operatively coupled to the penetrating member driver (34) so the penetrating member driver moves the active one along a path out of a housing (30) having a penetrating member exit, into the tissue site, stopping in the tissue site, and withdrawing out of the tissue site. The system further includes a plurality of analyte detecting members.
