First, a supervisor (i.e. the user mentioned above, which is used to mark each area correspondingly and plays a role of supervising the tested person to complete sample collection) takes out one piece of test paper 100, marks environment information (automatically displayed image or color, or digitized environment information obtained by the intelligent terminal according to the displayed image or color) in the environment mark area 140 correspondingly, marks the environment mark area 140 manually, drops a first sample from the tested person in the first detection area 131, generates a first detection result after a certain time, generates a first code according to the first detection result and the environment information by the supervisor (self-calculation or calculation through the intelligent terminal), and marks the first code in the identity mark area 150 by the supervisor. Another piece of test paper 100 is taken, the environmental information and the first code are marked in the designated area of the second piece of test paper 100, the second piece of test paper 100 is handed to the detected person, the detected person drops the second sample into the second detection area 132 of the second piece of test paper 100 after leaving the supervisor to generate a second detection result, and the supervisor generates a second code according to the second detection result and the first code and marks the second code area 120 of the second piece of test paper 100, so that the whole detection process is completed. After the detection is finished, the two test strips 100 are compared, the second codes of the two test strips are consistent with the detection result, if the second codes are inconsistent, the second test strip 100 is exchanged, and if the second codes are consistent but the second detection result is obviously inconsistent with the first detection result, the second sample on the second test strip 100 is not provided by the detector, and a counterfeit behavior exists in the second detection process.

In a preferred embodiment, as shown in fig. 2, the environmental imprint area 140 includes a timing imprint area 141 and a positioning imprint area 142, the timing imprint area 141 is used for recording the detection time, and the positioning imprint area 142 is made of a humidity-sensitive material for collecting and marking the environmental humidity during detection.

The positioning mark area 142 is used for marking the humidity of the external environment where the test strip 100 is located, the humidity changes by absorbing the moisture in the environment after the humidity-sensitive material is exposed in the air for a certain time (e.g., 30 seconds), and a humidity comparison table is used in cooperation with the humidity-sensitive material, so that a user can compare the color displayed by the humidity-sensitive material with the color of the humidity comparison table and read the humidity of the environment. The color that the humidity sensitive material shows still can carry out the accuracy through intelligent terminal and read, and intelligent terminal has stored the humidity reference list, compares in order to read environment humidity through the color that the humidity sensitive material shows and the color of humidity reference list equally, and the result that intelligent terminal read compares the naked eye and reads more accurately. The humidity sensitive material can adopt a polyvinylidene fluoride/hydroxyethyl cellulose blend, a humidity sensitive film made of modified polyimide, a graphene oxide film and the like.

The embodiment adopts the timing mark area 141 and the positioning mark area 142 to mark the environmental information, so as to better record the environment of the test strip 100 when being used and prevent the test strip from being exchanged. Meanwhile, when the detection result of the detection test strip 100 is analyzed, the environmental information may also be used as a reference factor, for example, in the morning and afternoon, the concentration of a substance in a body fluid (or blood) of a subject may change, different environmental humidities may have an influence on the detection area 130 of the test strip, and the like, and the reference factor is listed in the analysis of the detection result, which may help to obtain a more accurate detection and analysis result.

A light-sensitive area correspondingly contains a number, and when the user needs to mark the detection time on the test strip 100, a light source (e.g. near-uv) with a specific wavelength can be used, corresponding to the target number corresponding to the current time, for example: two and thirty minutes in the afternoon correspond to 0, 2, 3, 0 four light sensitive areas (to reduce the numerical repetition rate, the time is preferably recorded at 12 o' clock, also preferably exactly to half an hour, i.e. the last two digits are always 00 or 30; if necessary, am, pm two light sensitive areas can be added to indicate am and pm respectively), and a preset time, for example 10 seconds, is illuminated for changing the color of the illuminated light sensitive areas, thus forming a record of the time. For another example, two numbers in 11:00 are repeated, corresponding to two photosensitive regions of 1 and 0, two numbers in 11:30 are repeated, corresponding to three photosensitive regions of 1, 3 and 0, and the repeated numbers can be changed into specific colors by adopting light rays with different intensities, for example, the number used once is blue, the number repeated twice is purple, the number repeated three times is black, and the like, in this case, the photosensitive regions can be prepared by adopting a structure comprising polyurethane and a core-shell structure WO₃-photochromic paint composed of Ag nano material.

Under some conditions, a user does not want the recorded time to know by others, the photosensitive area can adopt reversible light-variable anti-counterfeiting ink, the chemical substance A in the photosensitive area is converted into a chemical substance B under a certain illumination condition, the first color of the photosensitive area is converted into a second color different from the first color, the chemical substance B reversely generates the chemical substance A after the photosensitive area is irradiated or heated by a light source with another wavelength, the second color of the photosensitive area is recovered into the first color, and others cannot know that the photosensitive area is marked; when the recorded time needs to be read, the photosensitive area is irradiated again under the original illumination condition, so that the marked photosensitive area can display a second color different from other unmarked photosensitive areas which are displayed as the first color, and the detection time of the mark can be obtained.
