Abstract

The method and device for judging blood agglutination, pre-place blood cells or serum of known blood type in the sample wells of the micropore plate, and place the blood cells or serum of the tested blood in each sample hole to form a reaction sample; scan the reaction sample in the sample hole Obtain the absorbance value of the absorbing point, define the effective absorbing point range centered on the middle absorbing point, and eliminate the absorbing points with errors on the edge; within the effective absorbing point range, select the minimum absorbance value and maximum absorbance value; use the minimum absorbance value as the base , obtain the difference between the maximum absorbance value and the minimum absorbance value, calculate the ratio of the difference to the minimum absorbance value as the base; preset the agglutination reference value, compare the ratio with the agglutination reference value, and when the ratio is greater than the agglutination reference value, set The blood in the sample hole is judged as agglutination, and when the ratio is less than or equal to the agglutination reference value, the blood in the sample hole is judged as non-agglutination. Quickly judge whether there is agglutination in the mixed sample, with high accuracy and wide application range.

Description

technical field [0001] The invention relates to a blood coagulation judging method and device, and relates to the technical field of blood processing. Background technique [0002] As we all know, blood agglutination is a serum immune reaction that may occur when blood of different blood types meet. It can be seen under a microscope that blood cells in the blood will adhere to each other and form a group. The microplate reader has the highest penetration rate in various blood stations, hospitals and various blood laboratories, and the microplate reader has a scanning function. [0003] At present, there are several methods for judging blood coagulation: one is the image analysis method, which judges whether the blood has coagulated by capturing images and analyzing the images. instrument. The other is to judge by naked eyes, such as ABO blood type test card. The first way, using large-scale equipment, cannot be used due to high cost and low penetration rate; the second wa...
