A depth-control mechanism for selectively-adjusting a lancing stroke depth of a lancet carrier. The depth-control mechanism includes a positioning tab that is configured to be repositioned along an axis that is orthogonal to the lancing stroke axis of the lancet carrier. The depth-adjustment mechanism also includes a tether that is pivotally coupled between the positioning tab and the lancet carrier. The positioning tab is configured to manipulate a pivot axis of the tether to adjust the lancing stroke length of the lancet carrier.
