Abstract: A testing system for conducting electrochemistry analysis of a specimen sample is provided. The testing system includes a testing receptacle device and a diagnostic device. The testing receptacle device includes a receptacle having an interior space defined therein and a lid configured to be secured on an upper end of the receptacle. The lid includes an opening extending into the receptacle and a cartridge slot for receiving a test sensor cartridge having a functionalized electrode strip with an electrode well contact point provided thereon. The diagnostic device is configured as a potentiostat or similar device and includes a docking port for receiving a lower end of the testing receptacle device. The testing system is configured for receiving a specimen sample through the opening in the receptacle lid and placing the specimen sample in contact with the electrode well contact point of the functionalized electrode strip.
