ABSTRACT:
An analyte test strip for accepting diverse bodily fluid sample volumes includes a first insulating layer, a second insulating layer disposed above the first insulating layer, and a third insulating layer disposed below the first insulating layer. The third insulating layer has a platform portion that extends beyond the first and second insulating layers and an upper surface. The analyte test strip also has a patterned spacer layer positioned between the first and second layers. The patterned spacer layer defines a channel between the first and second insulating layers that has a sample-receiving chamber, a first port proximate the platform portion and a second port at an outer edge of the analyte test strip. Moreover, the first port and the second port are in fluidic communication with the sample-receiving chamber. In addition, 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 transfer at least a portion of the first bodily fluid sample to the sample-receiving chamber via the first port. The second port is configured to receive a second (relatively small) bodily fluid sample of lesser volume than the first bodily fluid sample and to transfer at least a portion of the second bodily fluid sample to the sample-receiving chamber.
