1. A measurement module for analyte testing comprising:

  • a housing having a test strip receptacle and a connector portion, wherein the connector portion provides a direct connection between the measurement module and a processing device;

    a glucose measurement circuit for determining the amount of glucose present in a sample;

    at least one optoisolator for transmitting data across a power isolation barrier between the measurement module and the processing device;

    an isolated power module; and

    a transformer-coupled power transfer circuit that bridges the power isolation barrier and thereby transfers isolated power from a power source to the isolated power module.
