1. A body fluid sampling device, comprising:
- a lancing device configured to create an incision in a surface of tissue;
a fluid detector configured to detect sufficiency of body fluid bled from the incision while on the surface of the tissue;
an expression device operatively coupled to the fluid detector;
the fluid detector being configured to have the expression device automatically express the body fluid from the incision upon detecting that the body fluid on the surface of the tissue is insufficient for analysis; and
an analysis device configured to analyze the body fluid once the fluid detector detects that the body fluid on the surface of the tissue is sufficient for analysis.

Abstract
A bodily fluid sampling device is operable to breach the skin surface and allow bodily fluid to emerge from the breach location. The bodily fluid sampling device further evaluates the amount of bodily fluid emerged from breach location and determines whether the amount is sufficient or insufficient for a particular purpose, such as sampling and testing. The determination is accomplished automatically without moving the device. The user may also intervene to perform a variety of tasks following the determination of the amount of bodily fluid.

14. A body fluid sampling device, comprising:
-
a test strip including a capillary channel for drawing body fluid from a tissue and an analysis portion located along the capillary channel for analyzing the body fluid; and
wherein the test strip has a fluid detector to sense sufficiency of the body fluid on the tissue before the body fluid is drawn into the capillary channel. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A method, comprising:
-
placing a sampling device against tissue;
creating an incision in the tissue with the sampling device;
detecting with the sampling device that body fluid bled from the incision on the tissue is insufficient for analysis; and
expressing the body fluid from the incision automatically with the sampling device in response to said detecting while the sampling device remains against the tissue. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
