1. A method for determining a concentration of an analyte in a sample using a biosensor system, the biosensor system including a container comprising a desiccant blend including molecular sieve and silica gel desiccants and a plurality of test sensors, each of the plurality of test sensor including a reagent composition, the container including a predetermined amount of the desiccant blend to provide a predetermined moisture level in the container, the method comprising:

  • removing one of the plurality of test sensors from the container;

    contacting the removed test sensor with one of a plurality of samples including an analyte, each of the plurality of samples having an analyte concentration ranging from about 50 mg/dL to about 600 mg/dL; and

    using a measuring device to measure the analyte concentration in the one of the plurality of samples,wherein the biosensor system is configured to result in a bias of each measured analyte concentration compared with a reference value being within ±

    10 mg/dL for samples having an analyte concentration less than 100 mg/dL and within ±

    10% for samples having an analyte concentration of at least 100 mg/dL after storage in the container for about two weeks at a temperature about 50°

    C.
