Problems solved by technology

For example, the glass slide method is easy to operate and is suitable for the inspection of a large number of specimens, but the reaction time is long. If the serum antibody titer of the examinee is low, it is not easy to cause red blood cell agglutination; the test tube method: with the help of centrifugal force, the red blood cells can be closely contacted to promote agglutination. , but the instrument needs special personnel to operate
Therefore, the existing blood typing methods are difficult to meet the needs of various fields, especially the clinical field.

example 1

[0034] Example 1: ABO blood type detection.

[0035] Steps:

[0036] 1. Place the blood type test card horizontally on a dry workbench;

[0037] 2. Use the sampling unit to take 10 microliters of finger blood samples (at the second scale line), and add 5 microliters of samples to the two sampling holes 4 respectively;

[0038] 3. Gently pick up the blood type test card, push the buffer pool 7 into the housing with a little force, and place the test card vertically on the workbench (with one end of the buffer pool facing down), let it stand for about 10 seconds, and it can be read by naked eyes Typing results, you can also put the blood type card into the card slot of the detector used with it to interpret the typing results.

Abstract

The invention belongs to the field of blood typing detection, and particularly relates to a rapid blood typing detection card. A detection reagent strip comprises a sample pad, an upper absorbent pad and a lower absorbent pad, the sample pad is arranged between the upper absorbent pad and the lower absorbent pad, solution in a buffer unit is sucked into the sample pad by chromatography of the lower absorbent pad, the upper absorbent pad similarly has chromatography for the sample pad, and blood types are judged according to color change caused by blood typing reaction of blood in the sample pad. The rapid blood typing detection card has the advantages of portability, integration, sanitation, typing rapidness and easiness in operation.

Description

technical field [0001] The invention belongs to the field of blood type typing detection, in particular to a portable and integrated rapid blood type typing detection card. Background technique [0002] Blood type usually refers to the type of specific antigen on the red blood cell membrane, and its classification is based on whether there are certain heritable antigenic substances on the surface of red blood cells. If the blood of two people with incompatible blood types is dropped on a glass slide and mixed, red blood cells can clumped into clusters. This phenomenon is called erythrocyte agglutination. The mechanism causing agglutination is an antigen-antibody reaction. There are also specific glycoprotein antigenic substances on the surface of red blood cells collectively known as agglutinogens (Agglutinogen). Plasma contains the corresponding specific antibody, called agglutinin (Agglutinin). The commonly used blood group systems are ABO system and Rh system. [0003...
