A self-contained, disposable cartridge concept for complete blood counts

A true Point-Of-Care blood analyzer for counting Thrombocytes, Leucocytes (with three part differential counts: Lymphocytes, Monocytes and Granulocytes) and measurement of Hemoglobin is presented. The apparatus comprises a single use cartridge, called the PAQ, and a stationary Reader with a Cradle for receiving the PAQ. The PAQ includes two independent technologies: a micro machined sensor for impedance cell sizing and an optical absorption measurement system. The test procedure is very simple; the user is only required to apply a drop of blood to the PAQ and place it into the cradle. The rest of the test is carried out automatically within 3 minutes.
