Abstract: A device (100) to non-invasively determine a concentration of an analyte in a sampling volume (126) has a pulsed light source (114). A doped glass (104) has dopants that can emit fluorescence in a fluorescence wavelength range that at least partially overlaps with an absorption wavelength range of the analyte. The fluorescence has a first temporal fluorescence emission distribution in response to optical excitation by the pulsed light source (114) when the analyte concentration in the sampling volume is zero. A semi-transparent mirror (108) is interposed between the doped glass (104) and the sampling volume (126), such that the dopants emit fluorescence having a second temporal fluorescence emission distribution that is a function of the concentration of the analyte in the sampling volume (126).

Abstract: An integrated blood test unit including a blood collection recess, a test component, and a reservoir containing test fluid. The blood collection device moves to a delivery position under control of an actuator, which also releases test fluid from the reservoir onto the test component. Additional features are a window over the test outcome indicator, a blood delivery channel that only operates if the sample size is large enough, and a geometry for a lancet and actuator that is adapted for a self test situation.
