1. A body fluid sampling system for use on a tissue site, comprising:
- a drive force generator;
a housing with at least a proximal portion and a distal portion, the proximal portion being a handle portion configured to be held by a user, at least a portion of the distal portion having an ergonomically contoured surface adapted to conform to a tip of a finger;
a plurality of sample chambers and a plurality of penetrating members operatively couplable to the drive force generator, each of a sample chamber being associated with a penetrating member;
a disposable that houses the plurality of sample chambers and the plurality of penetrating members, the disposable being positioned in the distal portion of the housing;
a penetrating member sensor positioned to monitor the penetrating member coupled to the force generator, the penetrating member sensor configured to provide information relative to a depth of the penetrating member through a skin surface; and
wherein the penetrating member sensor is further configured to provide an indication of velocity of the penetrating member.
