Researchers from the University of Illinois have developed a handheld device to provide a complete blood count at the point-of-care. Based on microfluidics and impedance measurements, Dr. Bashir has also implemented mathematical models to better interpret the electrical signals in obtaining more accurate cell counts. This device is more portable, automated, and cheaper than existing devices. It utilizes single-use, disposable cartridges and replaces optical fluorescence detection with only electrical methods, eliminating the need for light sources, filters, and lenses. This device allows for a greater accuracy as compared to existing point-of-care devices and tracks well with the gold-standard of flow cytometry. It also provides a cheaper, faster, and easier method of performing a complete blood count, whether in the field or at a small doctor's office.
