Embodiment 1

[0040] An identification method for an agglutination test, the specific steps of the identification method are:

[0041] Step 1: using a camera or a video camera to obtain a sample image, and extracting the pattern of the test area in the sample image and placing it in a background of a fixed size to obtain an image of the sample image after extraction;

[0042] Step 2: adjusting brightness and contrast parameters of the extracted image described in step 1, so as to strengthen the effective information of the extracted image;

[0043] Step 3: Adjust the input range of each color component under each channel of the image R / G / B, and then perform histogram equalization, and adjust the gamma factor γ=0.95, and then obtain the adjusted image;

[0044] Step 4: Convert the adjusted image described in Step 3 into a grayscale image;

[0045] Step 5: Denoise the grayscale image described in step 4 to obtain an image for judging the experimental results;

[0046] Step 6: Convert the gr...

Embodiment 2

[0054] This embodiment takes the passive gelatin agglutination method of Mycoplasma pneumoniae antibody and Treponema pallidum gelatin particle method (TPPA test) as examples to illustrate and illustrate the interpretation methods.

[0055] First, take the passive gelatin agglutination method of Mycoplasma pneumoniae antibody as an example

[0056] Perform agglutination reaction on the MP antibody samples with various results on the test micro-reaction plate according to the operation specification of the passive gelatin agglutination method for the Mycoplasma pneumoniae antibody.

[0057] Perform image preprocessing on the obtained test results to obtain digital images of the agglutination test results (for example: use a digital camera to shoot the agglutination test micro-reaction plate), extract the information of the test area in the image, and place it in a fixed size of 72px×72px (M *M) in a white (255,255,255) square background. At the same time, the brightness and co...

Abstract

The invention provides a method for identifying an agglutination test and belongs to the technical field of medical detection methods. The identification method comprises converting an agglutination test result into digital graphic information through a camera or a video camera, and then identifying the result level of the agglutination test by computer image processing. The method can effectivelyreduce the error rate caused by human subjective recognition of test results.

Description

technical field [0001] The invention relates to an identification method for an agglutination test, belonging to the technical field of medical detection methods. Background technique [0002] The soluble antigen (or antibody) is adsorbed on the appropriate particle carrier, interacts with the corresponding antibody, and agglutination phenomenon occurs under the condition of suitable electrolyte. When the corresponding antibody fully reacts with the sensitized particles, the colored sensitized particles spread in a uniform network at the bottom of the reaction well, and the color of the image is evenly distributed and the color is lighter; when the soluble antigen does not react with the sensitized particles, the colored sensitized particles The sensitizing particles accumulate in a button shape in a small area at the bottom of the reaction well, and the color of the image is darker; when some soluble antigens react with the sensitizing particles, the sensitizing particle re...
