Cuda is a medical diagnostic device capable of detecting a life threatening condition called coagulopathy that occurs commonly in physical trauma patients. The device performs electrochemical analysis on a blood sample inserted by the user and returns the results upon test completion to a smartphone application over Bluetooth. This is an improvement over Aptitude’s current testing ecosystem that is only able to communicate test results via a simple 3 led interface. Cuda also provides many more features to Aptitudes medical testing ecosystem such as integrated patient data tracking, and test result visualization.
