Background
When the test strip for detecting the colloidal gold antigen based on blood is used, a hemolysis phenomenon caused by the rupture of red blood cells in the blood can occur with a certain probability, and the hemolysis phenomenon can cause the bottom plate of the reaction area of the colloidal gold test strip to appear dark red or light red. The colloidal gold wire (C, T wire) for marking the result can be dark red or purple red under the condition of illumination, and is similar to the red of the bottom plate caused by hemolysis, so that certain interference can be caused to the identification of the CT wire after the hemolysis phenomenon occurs, and misjudgment of the result is caused.
The existing test strip generally adopts two groups of photoelectric sensing structures which emit light and receive light (namely, one group of red light or infrared light emitting tubes emit light and one group of photoelectric triodes receive light).

For the convenience of understanding the present embodiment, first, a detailed description will be given of a test strip negative-positive identification method disclosed in the embodiments of the present disclosure, where an execution body of the test strip negative-positive identification method provided in the embodiments of the present disclosure is generally an electronic device with a certain computing capability, and the electronic device includes, for example: the terminal device or server or other processing device may be a User Equipment (UE), mobile device, cellular phone, cordless phone, personal digital assistant (Personal Digital Assistant, PDA), or the like. In some possible implementations, the test strip negative-positive identification method may be implemented by a processor invoking computer readable instructions stored in a memory.
Referring to fig. 1, a flowchart of a test strip negative-positive identification method provided by an embodiment of the present disclosure is shown, and the method includes the following steps S101 to S102:
s101: acquiring the dark green light reflection values respectively corresponding to three test bits on the test strip to be identified, wherein the three test bits are used for respectively indicating the test positions of the C line, the T line and the middle area of the T line;
s102: and performing color difference operation based on the cyan light reflection values respectively corresponding to the three test positions, and determining the negative and positive of the test strip to be identified.
In order to facilitate understanding of the test strip negative-positive identification method provided by the embodiment of the present disclosure, an application scenario of the method is first described in detail. The test strip negative-positive identification method in the embodiment of the disclosure can be mainly applied to the field of rapid detection of infectious diseases, for example, detection of AIDS virus (Human Immunodeficiency Virus, HIV), and can also be used in other detection fields, and is not particularly limited herein. Given the broad necessity of HIV detection, the following is exemplified by HIV detection.
When the detection is actually carried out, a sample to be detected (blood) can be added to a sample pad at one end of the test strip, then moves forward through capillary action, dissolves the colloidal gold labeled reagent on the binding pad, then reacts with each other, and moves to a fixed antigen or antibody area, and when the binding agent of the blood to be detected and the gold labeled reagent are specifically combined with each other to be trapped, the binding agent is gathered on the detection strip, and then a color development result can be observed through naked eyes, namely, the binding agent and the colloidal gold reagent are subjected to dominant display on a C, T line of the test strip through the electric adsorption characteristic of the antigen and the colloidal gold particle, so that the yin-yang result of the sample is judged.
Considering false positive and false recognition results possibly caused by adopting two groups of one-to-one photoelectric sensing structures in the related art, the embodiment of the disclosure adopts three groups of one-to-one test strip negative and positive recognition devices to carry out test strip negative and positive recognition, and as shown in fig. 2, the negative and positive recognition device mainly comprises a receiving and transmitting assembly 11 and a processing module 22; the transceiver component 11 is electrically connected with the processing module 22;
The receiving and transmitting assembly 11 is used for collecting the bluish green light reflection values respectively corresponding to three test bits on the test strip to be identified, wherein the three test bits are used for respectively indicating the test positions of the C line, the T line and the middle area of the T line;
and the processing module 22 is used for performing color difference operation based on the cyan light reflection values respectively corresponding to the three test bits to determine the negative and positive of the test strip to be identified.
The transceiver assembly 11 here includes three signal transmitting ends and three signal receiving tubes. As shown in fig. 2, three signal transmitting terminals (a c 、A b 、A t ) Three signal receiving pipes (B) c 、B b 、B t ) Pairing arrangement. The test paper strip to be identified reacts under the capillary action, and in the reaction process, A c 、A b 、A t The three test bit C lines, the middle area and the T lines on the test strip are respectively irradiated, and the specific range can be the positive and negative 0.5mm of the periphery of each test bit. Through B c 、B b 、B t And acquiring data of the transmitted signals to obtain reflection values corresponding to the three test bits respectively.
In order to further improve the accuracy of identification, the embodiment of the disclosure may use the cyan light with the main emission wavelength of 512nm to irradiate, which mainly considers that the cyan light has the excellent characteristics of stable irradiation signal, strong linearity, general activity and the like, and is not suitable for generating interference caused by red caused by hemolysis or other reactions, so that more accurate yin-yang identification can be performed through a color development combination.
The signal receiving tube here may employ a 0805-packaged photodiode, and perform signal reception in a voltage range of 3.3V, and the active wavelength range thereof is about 800 nm.
Based on the test strip negative-positive identification device, the test strip negative-positive identification method provided by the embodiment of the disclosure can obtain the cyan light reflection values of three test positions respectively collected by the three signal receiving pipes, and then, the negative-positive of the test strip to be identified is determined based on the cyan light reflection values respectively corresponding to the three test positions.
In the process of carrying out the test strip negative-positive identification, the color difference of the T line area and the middle area is mainly compared, for example, if the color of the T line area is heavier than that of the middle area, the test strip negative-positive identification is positive, and if the color of the T line area is similar to that of the middle area, the test strip negative-positive identification is judged to be negative. The color development combination performed by combining the middle region can perform more accurate judgment, and even under the condition that the blood trend is irregular, background color and other interferences exist, accurate yin-yang identification can be realized based on the color difference of the T line and the middle position.
In consideration of different influences of acquisition results at different moments on yin and yang identification, in the process of actually carrying out yin and yang identification, the embodiment of the disclosure can combine the cyan-green light reflection values at a plurality of moments corresponding to each test bit to carry out difference operation, so that more accurate yin and yang identification is realized. The method specifically comprises the following steps:
Step one, determining first turquoise light reflection values of a plurality of moments corresponding to a first test bit of an intermediate area and second turquoise light reflection values of a plurality of moments corresponding to a second test bit of a T line;
and secondly, performing color difference operation based on the first cyan light reflection values and the second cyan light reflection values, and determining the negative and positive of the test strip to be identified.
As the sample to be tested (blood) is applied to the sample pad at one end of the test strip, it is also necessary for a certain period of time for the development to actually occur due to capillary action moving forward. Here, in order to further improve the accuracy of the identification, the color difference operation may be performed based on the reflected light value of the green light collected in the preset effective sampling period, which may be specifically implemented by the following steps:
step one, performing color difference operation on a first cyan light reflection value and a second cyan light reflection value which are correspondingly acquired by sampling points aiming at each sampling point in a preset effective sampling period to obtain a color difference operation value;
step two, determining the color difference change rate corresponding to each sampling point based on the color difference operation value obtained by each sampling point;
and thirdly, determining the negative and positive of the test strip to be identified based on the color difference change rate corresponding to each sampling point.
Here, for each sampling point in the preset effective sampling period, the color difference operation value corresponding to the two test bits (namely the first test bit and the second test bit) can be determined, the color difference change rate of the corresponding sampling point can be obtained through the color difference derivation of the color difference operation value corresponding to each sampling point, and then the color difference change rate and the value for carrying out the yin-yang identification can be determined through the accumulation operation of the color difference change rate.
The preset effective sampling period may be a first sampling period and a second sampling period after the reaction, where the first sampling period may be, for example, a period of 5min to 8min, and the second sampling period may be, for example, a period of 12min to 15min, which mainly considers that the color development effect is optimal in the two sampling periods.
In practical application, the sum operation can be performed on the first color difference change rate sum value and the second color difference change rate sum value corresponding to the two sampling periods (i.e., the first sampling period and the second sampling period), so that yin and yang can be identified based on the sum result, and the method specifically comprises the following steps:
step one, summing the first color difference change rate sum value obtained by accumulation in a first sampling period and the second color difference change rate sum value obtained by accumulation in a second sampling period to obtain a color difference change rate total value;
Step two, under the condition that the total value of the color difference change rate is larger than 0, determining that the test strip to be identified is positive; and under the condition that the color difference change rate and the value are smaller than or equal to 0, determining that the test strip to be identified is negative.
Here, by summing the color difference change rates and values corresponding to the two sampling periods, the result of the identification of the yin and yang in the entire color development period can be determined.
The sampling period corresponds to a plurality of sampling points, whether for a first sampling period or a second sampling period. Taking a first sampling period as an example, 90 sampling points are corresponding in total in the period of 5min-8min, the color difference operation value between the first and second turquoise light reflection values corresponding to each sampling point respectively also changes along with the extension of sampling, and the color difference change rate of the sampling points can represent the color difference change condition between the first test bit in the middle area and the second test bit in the T line in the first sampling period; similarly, in the second sampling period of 5min-8min, the color difference change condition between the first test bit where the middle area is located and the second test bit where the T line is located can also be determined based on the color difference change rate, which is not described here again.
In practical application, for the color difference change condition between two test bits, if the color difference change rate corresponding to one sampling point is greater than a first preset threshold (for example, 1), it is indicated that the sampling data is invalid, and at this time, the corresponding sampling point can be screened out, so that the validity of the identification result is ensured.
Here, in order to further ensure the validity of the identification result, before the actual color difference operation is performed, it may be verified whether the reflection coefficient corresponding to the preset sampling time meets the threshold judgment condition, and in the case where it is verified that the reflection coefficient meets the threshold judgment condition, the color difference operation is performed based on the reflected value of the cyan light collected in the preset effective sampling period.
The reflection coefficient corresponding to the preset sampling time may be determined by a ratio between a cyan light reflection value corresponding to the test bit at the preset sampling time and a cyan light reflection value corresponding to the test bit at the initial power-on time, and specifically may be determined by ratios respectively corresponding to the three test bits together.
The preset sampling time may be, for example, an initial time of starting the reaction, and at this time, the subsequent color difference operation may be performed by verifying that the reflection coefficient corresponding to the initial time is smaller than a second preset threshold (e.g. 0.85); for example, the effective time of the effective reaction may be a valid time, and the subsequent color difference operation may be performed by verifying that the reflection coefficient corresponding to the valid time is greater than a third preset threshold (e.g., 0.75).
In order to facilitate further understanding of the method for identifying the negative and positive of the test strip provided in the embodiments of the present disclosure, the following may be further described with reference to a schematic structural diagram of the device for identifying the negative and positive of the test strip shown in fig. 2.

7. If V is m >1 (corresponding to a first preset threshold), then it is determined that the sample value is invalid for the first sampling period, and similarly, if V n >1 (corresponding to a first preset threshold), determining that the sampling value in the second sampling period is invalid;
8. calculating the total value of the color difference change rateIf V is>And 0, judging that the test strip is positive, and judging that the test strip is negative if V is less than or equal to 0.
In summary, it is known that the test strip negative-positive identification method provided by the embodiment of the present disclosure distinguishes negative positive by comparing the difference of the color development changes of the T line region and the middle region. However, the calculated values themselves differ due to factors such as installation errors, structural errors, resistance errors, production errors of the lamp and the receiving tube, and the like. The color difference is led, so that the change rate of the color difference of the T line position and the middle area is obtained, the yin-yang expansion judgment is further carried out, the interference and the error caused by the used components can be accurately eliminated, and the recognition rate of the color development of the test paper strip can be improved better.
In addition, background color such as blood is used as interference color of test strip color development, the embodiment of the disclosure introduces color value of the middle area, and the difference of the chromatic difference on the test strip is represented by calculating the chromatic difference change rate of the T line and the middle area, so that influence caused by the interference color is eliminated, and recognition accuracy is further improved by combining with light irradiation of cyan.
