PURPOSE: Provided are an apparatus and a method for collecting a physiological sample by perforating the skin and making a contact with the physiological sample in the skin. CONSTITUTION: A skin-piercing element(30) includes fluid pathway or channel(16) having a distal portion(18) and a proximal portion(37), where the fluid pathway(16) terminates proximal to a distal tip(20). The fluid pathway(16) runs through a portion of distal end(32) in such a way that a substantial portion of both the distal portion(18) and the proximal portion(37) of the fluid pathway are open to the outside environment along the entire length of the skin-piercing element. In other words, the fluid pathway forms a slit or groove through the skin-piercing element. The skin-piercing elements, due to the relatively greater surface area of one or more sides of the skin-piercing element, is the ability to access a greater sampling area. |
