Diagnostic test strip for collecting and detecting an analyte in a fluid sample
First Claim
1. A test strip for use in the determination of an analyte in a fluid sample, the test strip comprising:
- a base having a top and a bottom;
a collection chamber extending from the bottom of the base;
a containing ring disposed on the bottom of the base, the containing ring surrounding the collection chamber;
a capillary channel positioned adjacent to the top of the base, the capillary channel having an inlet fluidly coupled to the collection chamber;
a test area in fluid communication with the capillary channel;
a test element being disposed within the test area; and
a lid attached to at least a portion of the top of the base, the lid covering at least a portion of the collection chamber, the test area, and the capillary channel,wherein the capillary channel extends beyond the test area to form a vent.
