A reagentless whole-blood analyte detection system (200, 400, 450, 1000, 1100) that is capable of being deployed near a patient has a source (220) capable of emitting a beam of radiation that includes a spectral band. The whole-blood system (200, 400, 450, 1000, 1100) also has at least one detector (250, 1152, 1154) in an optical path of the beam. The whole-blood system (200, 400, 450, 1000, 1100) also has a housing (402, 452) that is configured to house the source (220) and the detector(s) (250, 1152, 1154). The whole-blood system (200, 400, 450, 1000, 1100) also has a sample element (240, 305, 605, 805, 885, 905, 1040, 1205, 1305, 1355, 1405) that is situated in the optical path of the beam. The sample element (240, 305, 605, 805, 885, 905, 1040, 1205, 1305, 1355, 1405) has a sample cell (242, 310, 610, 810) and a sample cell wall (244, 330, 335) that does not eliminate transmittance of the beam of radiation in the spectral band. |
