An integrated lancing test strip device includes a lancet configured to
form an incision in tissue and a test strip coupled to the lancet for
analyzing body fluid. A retention mechanism acts as a detent to hold the
lancet in a static position relative to the test strip before forming the
incision. The retention mechanism is configured to release the lancet for
retracting the lancet relative to the test strip to reduce smearing of
body fluid by the lancet during collection of the fluid with the test
strip. In one form, the retention mechanism includes breakable tabs that
are broken to release the lancet, and the lancet is retracted via
translational movement. The retention mechanism in another form includes
one or more dimples that release the lancet when the lancet is retracted
via rotational motion. In a further form, the entire integrated device is
rotated to collect fluid.
