Abstract
A method of manufacturing an analyte test strip includes positioning a patterned spacer layer between a first insulating layer and a second insulating layer such that the second insulating is disposed above the first insulating layer and a channel is defined between the first and second insulating layers. Moreover, the channel thus defined has a sample-receiving chamber therein, a first port, and a second port. The method also includes coupling a third insulating layer to the first insulating layer such that the third insulating layer is disposed at least partially below the first insulating layer. In the coupling step, the third insulating layer includes a platform portion that extends beyond the first insulating layer and the second insulating layer and the platform portion has an upper surface. In this manufacturing method, the first and second ports are in fluidic communication with the sample-receiving chamber; the upper surface of the platform portion is configured to receive a first (relatively large) bodily fluid sample of at least 5 micro-liters and for filling the sample-receiving chamber with a portion of the first bodily fluid sample, and the second port is configured t…
