Abstract

A bodily fluid sampling device (40) is operable to lance with a precise depth and express fluid from both fingertip and alternate sites. The bodily fluid sampling device (40) includes a lancet (50) adapted to form an incision in skin. In one form, the device (40) is operable to adjust the penetration depth of the lancet (50) into the skin (S). A skin contacting member (46) has an orifice (84) through which the lancet (50) extends when lancing the skin. The orifice (84) has a first opening size that is sized to flatten the skin around the lancet (50) during lancing. The orifice (84) has a second opening size that is larger than the first opening size after the incision is formed to express fluid from the incision.
