Abstract
A lancet enclosed in a sterility sheet forms a lancet packet to maintain the sterility of the lancet and prevent the lancet from unintentionally piercing the sterility sheet prior to lancet actuation. In one form, the lancet is immobilized by hot tack welding a portion of the sterility sheet to the lancet. Alternatively, portions of the sterility sheet are hot tack welded together through an opening in the lancet to limit movement of the lancet.
