METHODS AND APPARATUS FOR SAMPLING AND ANALYZING BODY FLUID
First Claim
1. A method, comprising:
- placing a lancing device against skin, wherein the lancing device houses a disposable that includes a lancet and a test strip;
wherein the test strip of the disposable includes printed electrical circuit paths;
wherein the lancing device includes an electrochemical meter with electrical leads;
forming an incision in the skin with the lancet of the disposable by firing the disposable towards the skin, wherein during said firing the lancet and the test strip of the disposable move together as a single unit towards the skin;
contacting the electrical leads of the electrochemical meter to the printed electrical circuit paths of the test strip of the disposable after said forming the incision; and
analyzing body fluid from the incision with the test strip of the disposable by electrochemical analysis.

Abstract
A sampling device for sampling body fluid includes a lancet for making an incision, a capillary tube for drawing-up body fluid from the incision, and a test strip affixed to an upper end of the capillary tube for receiving the fluid. An absorbent pad can be disposed between the test strip and capillary tube for spreading-out the fluid being transferred to the test strip. An on-site analyzer such as an optical analyzer and/or an electrochemical analyzer can be mounted in the device for analyzing the fluid. Alternatively, a test strip can be slid through a slot formed in the bottom end of the device so that by passing the device against the skin after an incision has been formed, the test strip will directly contact body fluid emanating from the incision.
