An analysis assembly (12) for analyzing one or more physiological parameters of a person (10) comprises a sensor assembly (14) and an analyzer (16). The sensor assembly (14) includes a sampler (218) that collects a sample (220) from the person (10) and a signal generating apparatus (222) that directs a mid-infrared light beam (232) toward the sample (220) and performs spectroscopy on the sample (220) to generate a signal (215) that is based at least in part on the one or more physiological parameters of the person (10). The sampler (218) and the signal generating apparatus (222) can be positioned less than approximately one meter from the person (10) while the sample (220) is being collected and spectroscopically scanned to generate the signal (215). The analyzer (16) receives and analyzes the signal (215) to determine the presence of the one or more physiological parameters in the sample (220).
