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.
