Analyte test strip for accepting diverse sample volumes
First Claim
1. An analyte test strip for accepting diverse bodily fluid sample volumes and determining an analyte therein, the analyte test strip comprising:
- a first insulating layer;
a second insulating layer disposed above the first insulating layer;
a third insulating layer disposed at least partially below the first insulating layer, the third insulating layer including;
a platform portion that extends beyond the first insulating layer and the second insulating layer, the platform portion having an upper surface;
a patterned spacer layer positioned between the first insulating layer and the second insulating layer, the patterned spacer layer defining;
a channel between the first insulating layer and the second insulating layer, the channel having;
a sample-receiving chamber therein;
a first port proximate the platform portion anda second port at an outer edge of the analyte test strip;
wherein the first port and the second port are in fluidic communication with the sample-receiving chamber; and
wherein the upper surface of the platform portion extends outwardly from the first port and is configured to receive a first 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; and
wherein the second port is configured to receive a second bodily fluid sample of lesser volume than the first bodily fluid sample and for transferring at least a portion of the second bodily fluid sample to sample-receiving chamber.

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.
