Abstract: An method of malaria detection includes providing an interdigitated sensor having a first electrode with a plurality of fingers and a second electrode with a plurality of fingers, interspersed and spaced apart from the fingers of the first electrode. A quantity of blood to be tested is received on the sensor. The blood is to be dried and is measured for at least one measurable characteristic, including a resistance of the blood. The presence of malaria infected blood is determined based on a comparison between the measurable characteristics and a predetermined threshold related to the measurable characteristics.
