Abstract: System and method of determining an amount of an analyte in a blood sample using a cartridge and blood collector are disclosed. The blood collector has a mounting surface, a capillary structure with a curved portion, and a capillary inlet. The cartridge has a receiving surface, a cartridge inlet, a microfluidic structure, and a measurement structure. The method includes placing the blood sample into the capillary inlet; attaching the mounting surface to the receiving surface; rotating the cartridge about a rotational axis to transport the blood sample from the capillary structure to the cartridge inlet and into the microfluidic structure; controlling the rotation of the cartridge to process the blood sample into the processed sample using the microfluidic structure; controlling the rotation of the cartridge to transfer the processed sample to the measurement structure; and measuring the amount of the analyte using the measurement structure and a measurement system.
