Patent ID: 11047824

Abstract:
A system for diagnosing COVID-19 infection. The system includes an electrochemical probe with three needle-shaped electrodes configured to be inserted into a sputum sample, an electrochemical stimulator-analyzer electrically connected to the electrochemical probe, a memory having processor-readable instructions stored therein, and a processor configured to access the memory and execute the processor-readable instructions to perform a method. The method includes applying a sweeping range of electrical potentials to the electrochemical probe utilizing the electrochemical stimulator-analyzer, measuring a set of generated electrical currents versus the applied sweeping range of electrical potential utilizing the electrochemical stimulator-analyzer, receiving the set of electrical currents from the electrochemical stimulator-analyzer, measuring a level of reactive oxygen species (ROS) in the sputum sample by measuring a current peak of the set of electrical currents, and detecting a COVID-19 infection status based on the measured level of ROS. Detecting the COVID-19 infection status includes detecting an infection with COVID-19 if the measured current peak is in a first range of current peaks and detecting a non-infection with COVID-19 if the measured current peak is in a second range of current peaks.
