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.
