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.

L'invention concerne un système de détection d'un analyte de sang entier sans réactif (200, 400, 450, 1000, 1100) pouvant être mis en place à proximité d'un patient. Ce système comprend une source (220) pouvant émettre un faisceau de rayonnement comprenant une bande spectrale. Ce système d'analyse de sang entier (200, 400, 450, 1000, 1100) comprend par ailleurs au moins un détecteur (250, 1152, 1154) situé dans un chemin optique du faisceau, un boîtier (402, 452) conçu pour renfermer la source (220) et le ou les détecteurs (250, 1152, 1154), ainsi qu'un élément échantillon (240, 305, 605, 805, 885, 905, 1040, 1205, 1305, 1355, 1405) situé dans le chemin optique du faisceau. Cet élément échantillon (240, 305, 605, 805, 885, 905, 1040, 1205, 1305, 1355, 1405) comprend une cellule échantillon (242, 310, 610, 810) et une paroi de cellule échantillon (244, 330, 335) qui n'affecte pas le facteur de transmission du faisceau de rayonnement dans la bande spectrale.
