Abstract
Embodiments of the invention include a test strip with a sample chamber opening spanning the width of the test strip at the sampling end and including a portion of the lateral sides at that end. The chamber is vertically bounded by upper and lower substrate layers, horizontally bounded by the front face of a spacer layer, and open on the remaining sides. The test strip fills rapidly and requires small sample volumes. Both 1-up and 2-up manufacturing techniques for producing such test strips eliminate registration and alignment steps, and other techniques relating to the 2-up technique (simultaneously manufacturing test strips arranged in multiple columns) are also disclosed.
