Abstract
Lancets comprising a piercing element for puncturing the skin of a patient, a test region containing detection reagents for determining an analyte concentration of a body fluid sample, a capillary structure arranged in the piercing element for transporting a body fluid sample to the test region, and a sterile protection element, which encloses the tip of the piercing element. The capillary structure is blocked in a section surrounded by the sterile protection element. Also provided are methods for producing a lancet, comprising: producing a piercing element, which on the upper side has an upwardly open capillary structure; covering a section of the upper side of the piercing element and blocking the capillary channel in this section using a first material; covering a section of the underside using a second material; sterilizing the piercing element; and attaching a test region containing detection reagents to the piercing element.
