Problems solved by technology
[0004] The existing result interpretation has the following problems: 1. Manual interpretation is greatly affected by human subjective factors, sometimes causing visual fatigue and easily causing result deviations
2. Since pathogenic microorganisms are usually detected, excessive contact with the human body poses biological safety hazards
3. Manual interpretation and recording is time-consuming and labor-intensive
4. Manual interpretation cannot automatically connect with the sample management information system and realize the automatic management of test results

Embodiment 1
[0060] see Figure 5 , the present invention discloses a hemagglutination test result interpretation device and a method for automatically recording and counting the test results, the method comprising the following steps:
[0062] Place the test 96-well blood coagulation plate on a rectangular bracket that matches the blood coagulation plate, adjust the angle of the blood coagulation plate according to the test results, so that the red blood cells in the sample well of the blood coagulation plate form a teardrop shape under the action of oblique force .
[0063] [Step S2] Interpretation of the results of the hemagglutination test;
[0064] First start the program, and 4 cameras take pictures of the sample holes on the hemagglutination plate at a fixed object distance; since the position of each hole is fixed, after taking pictures, the system cuts the image of each hole according to the fixed pixel position , to ca...

Abstract
The invention provides an automatic interpretation tool for a hemagglutination and hemagglutination inhibition test result. The tool is a device for automatically generating the result. An interpretation method for the tool comprises the following steps: adjusting a hemagglutination plate support to make erythrocytes form a teardrop shape; carrying out zoning photographing on hemagglutination plate sample holes in a fixed object distance, calculating the teardrop length of the erythrocytes, and finding out a target hole; and processing obtained results, storing original images and interpretation results in a database, carrying out classified statistics according to the test results of a sample and test items, gathering the sample, and outputting the results by clicking a menu. The hemagglutination and hemagglutination inhibition test interpretation device and the statistical method thereof allow 96 samples to be simultaneously interpreted in 4 seconds, so the interpretation speed is much faster than that of manual operation, and the time and the labor are saved. Manual analysis and discrimination are not needed by using the tool, so visual fatigue and misjudgment are avoided, and individual differences are avoided; and the possibility of personnel in contact with pathogens is reduced, and the tool can be connected with a sample information management system to realize automaticmanagement.
Description
technical field [0001] The invention belongs to the field of biological detection, in particular to a method and equipment for automatically interpreting and automatically generating results of hemagglutination and hemagglutination inhibition tests. Background technique [0002] Hemagglutination and hemagglutination inhibition tests are mainly used to detect antibody levels in serum, and can also be used to judge the infection status of a population. At present, this test is commonly used by the World Health Organization and the International Organization for Animal Health to detect major animal diseases such as avian influenza and Newcastle disease worldwide, and because of its advantages such as easy operation and the ability to handle a large number of samples, it has become the current grassroots veterinary test. The most commonly used method in indoor disease surveillance and immune antibody detection. [0003] During the hemagglutination and hemagglutination inhibitio...
