PORTABLE ELECTRICAL IMPEDANCE-BASED BLOOD TESTING DEVICE FOR DIAGNOSIS AND MONITORING SICKLE CELL DISEASE
An exemplary mobile impedance-based flow cytometer is developed for the diagnosis of sickle cell disease. The mobile cytometer may be controlled by a computer (e.g., smartphone) application. Calibration of the portable device may be performed using a component of known impedance value. With the developed portable flow cytometer, analysis may be performed on two sickle cell samples and a healthy cell sample. The acquired results may subsequently be analyzed to extract single-cell level impedance information as well as statistics of different cell conditions. Significant differences in cell impedance signals may be observed between sickle cells and normal cells, as well as between sickle cells under hypoxia and normoxia conditions.
