    Abstract: PROBLEM TO BE SOLVED: To perform quantitative assay accurately and quickly by containing the part including the detecting zone of an assay unit in a containing means and providing a detection zone on a passage between an intensity sensor for uniform diffusion electromagnetic radiation and a radiation source. SOLUTION: An assay strip 101 is contained between the upper and lower parts 200, 201 of a casing such that a water absorbing sample containing member 202 can elongate outward from one end 203. The upper and lower parts 200, 201 are provided, respectively, with openings 205, 209 and recesses 207, 210. A protrusion 305 in a slot 301 facing a light source 303 is fitted in the recess 207 and positioned in place. A plurality of LEDs 306 of the light source 303 irradiate the assay strip 101 through a diffuser 307 and the opening 209 and the light reaches to a plate 309 through the opening 205 and a diffuser 308. The plate 309 is provided with openings 310-314 corresponding to the detection line on the assay strip 101 and a photodetector 321 is provided at the distal end of each opening 310-314. This structure realizes a test strip reader which can be used easily even in a home.

    Abstract: PROBLEM TO BE SOLVED: To monitor an ovulocycle while avoiding the requirement for frequently conducting tests over the whole ovulocycle by providing multiple throwaway test devices each giving readable signals indicating the concentrations of at least two analytes in a significant humor regarding the pregnancy feasible state of the ovulocycle. SOLUTION: The readable signals of a monitoring device are generated by concentrating a detectable first material, preferably a marker reagent, in the first detection zone of a porous carrier, and concentrating a detectable second material, preferably a marker reagent, in the second detection zone of a porous carrier located on the downstream side of a first test zone while flowing in a porous carrier such as test strips in test devices. The first detection zone signal indicates the humor concentration of a first analyte showing the significant concentration change closely related to the actual ovulation time, and the second detection zone signal indicates the humor concentration of a second analyte or estrodiol showing the significant concentration change before the pregnancy feasible phase of an ovulocycle.

    Abstract: A method of "reading" the result of an assay effected by concentrating a detectable material in a comparatively small zone of a carrier in the form of a strip, sheet or layer through the thickness of which electromagnetic radiation such as visible light is transmissible, wherein at least a portion of one face of the car- rier is exposed to incident electromag- netic radiation which is substantially uni- form across the entire portion, the por- tion including the small zone, and elec- tromagnetic radiation emerging from the opposite face of the carrier is measured to determine the assay result. Preferably the radiation is diffuse light.
