Abstract
A bodily fluid sampling device includes a piercing device and a sensor enclosed in a housing. A cassette, which contains test media, is positioned proximal to the sensor so that the sensor is able to analyze a bodily fluid sample collected on the test media. The cassette includes a supply portion from which unused test media is supplied and a storage portion in which contaminated test media is stored after exposure to the bodily fluid. The cassette is adapted to collect a series of bodily fluid samples without requiring disposal of the test media.
