LANCET
First Claim
1. A lancet comprisinga lancet tip at a front end, andan upper face with a contact surface for placing a test element thereon, said upper face comprising at least one channel for receiving a sample, an upwardly open section of the channel running in the contact surface,characterized in thatthe channel has another upwardly open channel section, which runs on the upper face of the lancet in or adjacent to a surface area that is lower than the contact surface, wherein the contact surface is arranged between the lancet tip and the lower surface area.

Abstract
The invention relates to a lancet, which has a lancet tip at a front end and which on an upper face comprises a contact surface for placing a test element thereon and at least one channel for receiving a sample, wherein an upwardly open section of the channel runs in the contact surface. According to the invention, the channel has another upwardly open channel section which runs on the upper face of the lancet in or adjacent to a surface area that is lower than the contact surface, wherein the contact surface is arranged between the lancet tip and the lower surface area. The invention further relates to a system comprising such a lancet and a test element, and to a method for transferring a liquid sample from a channel of a lancet which is designed as a groove or slot to a test element.

15. A method for transferring a liquid sample from a channel of a lancet which is designed as a groove or a slot to a test element for analysis of the liquid sample by covering the channel with the test element, characterized in that the test element is placed on a surface region of the lancet in which a starting section of the channel runs, whereby a capillary gap forms between a second surface region of the lancet in which a second section of the channel runs and the test element, with liquid from the channel penetrating into the capillary gap due to capillary forces.
