The major components of the IRMA TruPoint system are a portable, battery operated analyzer, and disposable cartridges that contain sensors and a calibrant. Cartridges come in a variety of analyte configurations. Cartridges calibrate with every test using the self-contained calibrant. Instructions displayed on the interactive touchscreen guide the user through all steps of the testing process. Patient and sample information can be entered during analysis. Test results are displayed within approximately 90 seconds after sample injection. Test results and associated information can be automatically printed via the on-board printer. Test results and associated information can be transmitted via serial, LAN10/100, or modem port to the Integrated Data Management System (idms) or other connected system capable of accepting ASTM output.
