BODY FLUID SAMPLING DEVICE
First Claim
1. A testing device comprising a sampling element having a fluid pathway for receiving a sample fluid, wherein at least a portion of said fluid pathway is open to the environment and a fluid receiving means being out of fluidic contact from said fluid pathway so that fluid in said pathway will not contact the fluid receiving means initially wherein the fluid receiving means comprises two or more test zones.

Abstract
Body fluid sampling device comprising a sampling element having a fluid pathway (11) for receiving body fluid, at least a portion of the fluid pathway is open to the environment and further comprising a fluid receiving means (40) being spaced from the fluid pathway so that fluid in the pathway will not contact the fluid receiving means initially. The fluid receiving means has two or more test zones (45) for performing analytical reactions. Fluid from the channel is contacted with the fluid receiving means either by bringing the fluid receiving means and the fluid into mechanical contact or by electrically transporting fluid from the channel onto the fluid receiving means.

25. Method for determining an analyte concentration in body fluid comprising the steps of:
-
a) receiving body fluid in a fluid pathway of a sampling element, b) contacting the sampling element with a fluid receiving means comprising two or more test zones so that body fluid from a fluid pathway of the sampling element contacts the fluid receiving means and reaches at least one of said test zones, c) receiving signals from said at least one test zone which are characteristic for an analyte concentration d) processing said signals to determine an analyte concentration. - View Dependent Claims (26, 27, 28)

30. Analytical device comprising
a support structure having a channel for receiving fluid therein which is accessible from the surrounding in at least an access region, a fluid receiving means being spaced from the channel a source of electrical potential which when turned on applies an electrical potential between fluid in said access region and said fluid receiving means so that fluid from said access region is transported onto said fluid receiving means, wherein the fluid receiving means comprises two or more test zones.
-
31. Method for determining an analyte concentration in body fluid comprising the steps of:
-
a) receiving body fluid in a fluid pathway of a sampling element, b) contacting the sampling element with a first fluid receiving means comprising at least one test zone so that body fluid from a fluid pathway of the sampling element contacts the first fluid receiving means and reaches its at least one test zone, c) simultaneously or subsequently contacting the sampling element with a second fluid receiving means comprising at least one test zone so that body fluid from the fluid pathway of the sampling element contacts the second fluid receiving means and reaches its at least one test zone, d) receiving signals from the at least one test zone of the first and second fluid receiving means, e) processing said signals to determine analyte concentrations.
