In FIG. 2, all the display contents of the display unit 4 are shown. The feature of the display unit 4 is that a determination index is displayed based on the measurement result (measurement value), that is,
The point is that it has a portion 10 that displays three arrows and a portion 11 that specifies the determinations (“little detected”, “slightly detected”, “more detected”) corresponding to each arrow.

Although the portion 11 in which the judgment is clearly displayed is not displayed on the display portion 4 in this embodiment, the display portion 4 may be expanded and displayed beside the arrow display portion 10, or may be displayed. If the display area of the section 4 cannot be made so large, for example, three characters of “none”, “small”, and “large” may be displayed. Alternatively, it is also possible to separately prepare a sticker that clearly indicates them and attach the sticker to the side of the display unit 4 of the measuring device main body 2. Further, only the judgment index may be displayed without displaying the arrow or the measured value. However, the judgment is a guideline for the judgment that the measured value means until the user gets tired of it, and the prescription of the doctor does not change depending on the instructed judgment. Further, the determination of the determination display portion 11 in this embodiment is performed when the urine component is urine sugar, and the determination of the urine protein may be displayed as the urine component other than the urine sugar. Further, although the determination is divided into three, it may be finely divided into four or more.

In addition to the arrow display portion 10, the display portion 4 has a portion 12 for displaying the measured value, the number of days used, the number of times used, and the like.

These display forms and display contents are not much different from conventional ones,
Detailed description is omitted.

When the measured value is urine sugar, the judgment index is indicated according to the measured value as shown in FIG. 3, for example. When the measurement value is displayed, the sensor 3 needs to be washed after the measurement is completed, so that “wash” in the display portion 13 blinks to prompt the sensor 3 to be washed. At this time, when the measured value is 0, the display portion 12 displays “−0” and the arrow display portion 10 displays a lower arrow, as shown in FIG. Since the arrow below indicates “nearly detected” is the determination index, the measurer can easily recognize that the measured value (urine sugar) at this time has no problem. When the measured value is 50, as shown in FIG. 3B, the display portion 12 displays “± 50”, and the lower arrow is displayed. In this case as well, it is determined that the measured value has no problem.

When the measured value is 100, as shown in FIG. 3 (c), the display portion 12 displays "+100", the middle arrow is displayed, and it is determined that a small amount of urinary sugar has been detected.
When the measured values are 150, 250, 500 or more, they are displayed as in (d), (e), and (f) of FIG. 3, respectively, and the upper arrows are displayed together. In this case, it was determined that the measured values were large and urine sugar was detected in a large amount. That is, in this embodiment, when the measured value (urine sugar) is 0 to 50, "it is hardly detected", when it is 50 to 100, "it is slightly detected", and when it is 100 or more, "it is detected a lot".
