1. A fluid collection apparatus to test a concentration of an analyte in a fluid, comprising:
- a lid;
a base having a plane;
a spacer disposed between said lid and said base, said spacer including a capillary channel having an opening for receiving the fluid; and
a lance disposed between said lid and said base, said lance moveable relative to said base and parallel to said plane of said base, said lance having a piercing end that is moveable to a position adjacent said opening of said capillary channel, said lance extending beyond said lid and said base for puncturing.

Abstract
A fluid collection apparatus adapted to test a concentration of an analyte in a fluid, including a lid and a base. Further included is a spacer disposed between the lid and the base. The spacer forms a capillary channel, which has an opening and is designed to collect the fluid. The capillary channel includes a reagent that reacts with the fluid to produce a measurable reaction. The reaction will provide a measurable indication of the concentration of the analyte in the fluid. Coupled to the lid is a lance that is moveable to the base and is moveable to a position adjacent the opening of the capillary channel.

25. A fluid collection apparatus adapted to test a concentration of an analyte in a fluid, comprising:
-
a base;
a guide;
a pair of spacers disposed between said base and said guide, said pair of spacers defining a capillary channel having an opening; and
a lance coupled to said guide, such that a movement of said guide causes a movement of said lance parallel to a plane of said base, an end of said lance moveable to a position adjacent to said opening of said capillary channel;
wherein said capillary channel is adapted to collect the fluid, said capillary channel including a reagent adapted to produce a reaction indicative of the concentration of the analyte in the fluid. - View Dependent Claims (26, 27, 28)

29. A method for testing a concentration of glucose in a user'"'"'s blood utilizing a fluid collection apparatus having an integrated lance and a capillary channel located in the same plane, the method comprising:
-
placing an end of the capillary channel against the user'"'"'s skin;
pushing the lance into the skin so as to puncture the skin and draw blood;
pulling the lance out of the skin;
drawing the blood into the capillary channel without moving the fluid collection apparatus; and
measuring the amount of glucose in the blood. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36)
