1. A diagnostic system, comprising:
- a removable assay cartridge comprising fluid paths and a plurality of electrochemical sensors;
a removable calibration fluid cartridge;
a diagnostic device having a housing and processing electronics for conducting the diagnostics within the housing;
wherein the housing further comprises a first opening for receiving at least a portion of the removable assay cartridge and a second opening for receiving at least a portion of the removable calibration fluid cartridge;
wherein the processing electronics of the diagnostic device receive signals from the electrochemical sensors, and the removable assay cartridge and the removable calibration fluid cartridge engage for the communication of fluid so that there is no fluid communication from the removable assay cartridge to any surface of the diagnostic device and no fluid communication from the removable calibration fluid cartridge to any surface of the diagnostic device.
