1. A test strip to assist in determining the concentration of an analyte in a fluid sample, comprising:
- a base including a capillary channel that terminates at a test element, the capillary channel being in fluid communication with the test element, the test element being adapted to receive the fluid sample via the capillary channel;
a first tab removably attached to a first end of the base, the capillary channel extending from the test element in the base into a portion of the first tab such that the first tab includes a portion of the capillary channel;
a break line intersecting the capillary channel, wherein an inlet to the capillary channel is exposed along the break line when the first tab is separated from the base; and
a flexible strip, a first portion of the flexible strip being attached to the base, a second portion of the flexible strip being removably attached to the base, and a third portion of the flexible strip being attached to the first tab, wherein the flexible strip remains attached to the base and the first tab after the first tab is detached from the first end of the base.

Abstract
A test strip to assist in determining the concentration of an analyte in a fluid sample comprises a base, at least one tab and a break line. The base includes a capillary channel and a test element. The capillary channel is in fluid communication with the test element. The test element is adapted to receive the fluid sample. The at least one tab is removably attached to the base. The capillary channel extends from the base into a portion of the tab. The break line intersects the capillary channel in which an inlet to the capillary channel is exposed along the break line when the tab is separated from the base.

9. A test strip to assist in determining the concentration of an analyte in a fluid sample, comprising:
-
a base including a capillary channel and a test element, the capillary channel being in fluid communication with the test element, the test element being configured to receive the fluid sample and being used in determining the analyte concentration; a tab removably attached to a first end of the base, the capillary channel extending from the base into a portion of the tab; a flexible strip attached to the base and the tab, the flexible strip remaining attached to the base and the tab after the tab is detached from the first end of the base; and a break line intersecting the capillary channel, wherein an inlet to the capillary channel is exposed along the break line when the tab is at least partially separated from the first end of the base. - View Dependent Claims (11)
