1. An integrated sampling device, comprising:
- an incision forming member configured to form an incision in tissue, the incision forming member including a lancet and a pry member protruding from the lancet;
a test media configured to analyze body fluid from the incision;
a carrier coupling the incision forming member and the test media together, the carrier includinga tamper evidence link,living hinges having a first position where the tamper evidence link connects the living hinges together,the living hinges having expansion members with pry surfaces defining a pry cavity in which the pry member is received, wherein the pry member contacts the pry surfaces when in the pry cavity,the living hinges having a second position wherein the tamper evidence link is broken,andthe living hinges are configured to bend from the first position to the second position when the incision forming member is actuated; and
wherein the pry member is configured to break the tamper evidence link by prying the expansion members apart when the incision forming member is moved in a longitudinal direction.

Abstract
A bodily fluid sampling device is operable to lance with a precise depth and express fluid from both fingertip and alternate sites. In one form, the device is operable to adjust the penetration depth of the lancet into the skin. The bodily fluid sampling device includes a lancet adapted to form an incision in skin. A skin contacting member has an orifice through which the lancet extends when lancing the skin. The orifice has a first opening size that is sized to flatten the skin around the lancet during lancing. The orifice has a second opening size that is larger than the first opening size after the incision is formed to express fluid from the incision.
