Human and animal health are currently in a transition, where evidence-based rapid therapeutic intervention and self-monitoring for lifestyle optimisation are on the rise. Diagnostic technology will be provided at the time and place where it is needed. The key driver for this development are point of care (POC) devices providing decentralized rapid testing.
Those systems depend on miniaturised and automated processes with superior analytical performance, enabling earlier and more accurate disease detection and prevention. AIT has profound expertise in the whole analysis chain ranging from sample preparation, assays, biosensors, microfluidics, process control and data analysis towards the overall POC instrument. This system know-how enables us to develop single analysis modules, provide content for external POC platforms and to integrate all components into fully functional devices providing simple, fast, and user-friendly operation. With such systems home-testing and self-monitoring can be performed, enabling lifestyle optimisation and early detection for the prevention of diseases. In addition, these systems will facilitate rapid diagnostic answers directly at the patient or animal and empower health professionals for better, targeted and personalised treatment.
