A self contained disposable test unit for testing body fluid comprising: a body member a support member axially moveable with respect to the body member between a first position and a second position, the support member including a body part receiving surface for receiving a patient's body part, a lancet carried by the body member and including a lancet tip configured to pierce the skin of a patient to produce fluid flow; a test member configured to interact with body fluid to aid in the determination of information about body fluid components; a capillary member configured to direct fluid flow to the test member, a pressure cup configured to exert pressure on a body part to foster fluid flow out of a lanced site and into the capillary; and a calibration member containing information for facilitating calibration of the test unit; wherein the lancet is configured to move between a storage position wherein the tip is disposed below the body part receiving surface of the support member where the lancet cannot stick the user, a piercing position wherein the tip is disposed above the body part receiving surface of the support member and wherein the lancet can pierce a user to cause a fluid flow, and a retracted position wherein the tip is disposed below the body part receiving surface of the support member where the lancet is no longer capable of piercing the user, characterized in that the lance further includes: - a first end pivotably coupled to the body member to permit the lancet to pivot between the piercing position and the retracted position, - a radially extending first portion disposed adjacent to the first end, - a second end comprising a tip, and - a second axially extending portion coupled to the radially extending first portion and disposed adjacent to the second end, and wherein the lancet is moved into the retracted position through the engagement of an axially offset surface (184, 186, 188, 190, 192, 194) of the support member with the radially extending first portion of the lancet as the support member axially moves between the first and the second position. a body member a support member axially moveable with respect to the body member between a first position and a second position, the support member including a body part receiving surface for receiving a patient's body part, a lancet carried by the body member and including a lancet tip configured to pierce the skin of a patient to produce fluid flow;
