1. A method for collecting a body fluid for testing for an analyte contained within said body fluid, said method comprising:
- providing an apparatus comprising a conduit, a reservoir having a reservoir volume and a capillary test space having a test volume;
penetrating said conduit into a patient'"'"'s skin to access body fluid therein;
flowing said body fluid from the patient'"'"'s skin through said conduit;
discharging said body fluid from said conduit into said reservoir;
accumulating said body fluid within said reservoir; and
wicking a test volume of said accumulated body fluid from said reservoir to said capillary test space when said accumulated fluid attains said reservoir volume, wherein said reservoir volume is greater than said test volume.

Abstract
A body fluid is collected for testing for an analyte contained within the body fluid. The fluid is collected in an apparatus including a reservoir for receiving and collecting a flow of body fluid from a discharge end of a conduit. A capillary test space is in fluid flow communication with the reservoir. The capillary test space is positioned to be in contact with the fluid in the reservoir after the fluid has accumulated to a predetermined transfer volume of fluid. The capillary test space is sized to wick the fluid from the reservoir when the fluid contacts the capillary test space.

11. A method for collecting a body fluid for testing for an analyte contained within said body fluid, said method comprising:
-
providing an apparatus comprising a conduit, a reservoir having a reservoir volume and a capillary test space having a electrochemical test strip having at least one electrode and defining a test volume;
penetrating said conduit into a patient'"'"'s skin to access body fluid therein;
flowing said body fluid from the patient'"'"'s skin through said conduit;
discharging said body fluid from said conduit into said reservoir;
accumulating said body fluid within said reservoir; and
wicking a test volume of said accumulated body fluid from said reservoir to said test strip when said accumulated fluid attains said reservoir volume, wherein said reservoir volume is sufficiently greater than said test volume. - View Dependent Claims (12, 13)
