Microcolumn agglutination anti-human globulin detection card

Abstract

The invention discloses a microcolumn agglutination anti-human globulin detection card, and belongs to the technical field of medicine. The microcolumn agglutination anti-human globulin detection cardcomprises a card body. The card body is a hollow structure with an open top. The card body is provided with a partition plate. The inside of the card body is divided into two left and right detectionchambers through the partition plate. The two detection chambers are respectively provided with three microcolumn gel tubes and five microcolumn gel tubes. A sealing film covering all the microcolumngel tube nozzles is disposed on the top of the card body, and the sealing film is disconnected at the partition plate. The sealing film is respectively provided with tear-off strips at the left and right ends of the card body. The front and back sides of the card body are provided with logo stickers at positions corresponding to the two detection chambers. A writing strip is provided at an intermediate position of one of the logo stickers. The microcolumn agglutination anti-human globulin detection card has simple structure, can reduce human error, improve result accuracy, high specificity, high sensitivity, good repeatability, and convenient and quick operation.

Description

technical field [0001] The invention relates to a microcolumn agglutination antihuman globulin detection card, which belongs to the technical field of medicine. Background technique [0002] The anti-human globulin test is a classic serological method invented by Coombs et al. in 1945, also known as the Coombs test. It is mainly used to detect the antigenic reactions participated by antibodies such as IgG and IgA, and can also determine the participation of complement components C3 and C4 fragments. The immune response, including direct antiglobulin test DAT and indirect antiglobulin test IAT. [0003] Micro-column gel anti-human globulin detection card is a new method of immunological detection that has gradually emerged recently. It is an anti-human globulin test performed on red blood cells with incomplete antibodies and corresponding antigens in a gel medium containing anti-human globulin. . This method is the product of the combination of gel column and anti-human glo...

Problems solved by technology

In recent years, imported micro-column gel anti-human globulin cards have been used in China for the screening and identification of irregular antibodies and the detection of sensitized red blood cells. In addition, there are also the following defects: one is that the price is high and the equipment is expensive, which seriously affects its popularization in China; the other is that when the operator is a newly recruited worker, it is possible not to grasp the concentration of antibody screening red blood cells (red blood cells need to be prepared). into 1% concentration), resulting in inaccurate results and increasing experimental errors

Third, when the operator is extremely tired, especially when working alone, there is a risk of adding other red blood cells as irregular antibodies, thereby increasing the experimental error

Fourth, it takes a long time and many steps, and the interference of antibodies without clinical significance cannot be ruled out
