Embodiment 1

[0047] Embodiment 1 Carrier is the ABO blood type detection card of single serving of plane

[0048] The ABO blood type detection card is composed of a flat slide carrier 1 (medical slide) and an antibody layer 2 for detection fixed on the slide carrier 1, and the antibody layer is composed of two antibody blots.

[0049] The letter shapes of the antibody blots are the letter A and the letter B respectively, the antibody blot in the shape of the letter A is the anti-A antibody, and the antibody blot in the shape of the letter B is the anti-B antibody.

[0050] The antibody layer 2 is fixedly connected to the glass slide carrier 1 through the immobilization reagent on the surface of the carrier.

Embodiment 2

[0051] Embodiment 2 Carrier is the ABO blood type detection card of the single serving of concave surface

[0052] The ABO blood type test card is composed of a cardboard carrier 1 and a detection antibody layer 2 fixed on the cardboard carrier 1, and the antibody layer is composed of two antibody blots.

[0053] The letter shapes of the antibody blots are the letter A and the letter B respectively, the antibody blot in the shape of the letter A is the anti-A antibody, and the antibody blot in the shape of the letter B is the anti-B antibody. The detection area of ​​the cardboard carrier 1 has a concave structure 3 where the antibody blot is located.

[0054] The antibody layer 2 is fixedly connected to the carrier 1 through the immobilization reagent on the surface of the carrier.

Embodiment 3

[0055] Example 3 Carrier is a single ABO blood type test card with a convex surface and grooves

[0056] The ABO blood type test card is composed of a cardboard carrier 1 and a detection antibody layer 2 fixed on the cardboard carrier 1, and the antibody layer is composed of two antibody blots.

[0057] The letter shapes of the antibody blots are the letter A and the letter B respectively, the antibody blot in the shape of the letter A is the anti-A antibody, and the antibody blot in the shape of the letter B is the anti-B antibody. The detection area of ​​the cardboard carrier 1 has a convex structure 3, the antibody layer is located on the convex structure 3, and the peripheral ring of the convex structure 3 is provided with a groove 4 for collecting unreacted blood.

[0058] The antibody layer 2 is fixedly connected to the carrier 1 through the immobilization reagent on the surface of the carrier.

Abstract

The invention relates to a blood type test card and a production method thereof, belonging to the technical field of blood type test. The blood type test card consists of a carrier and an antibody layer fixed on the carrier, wherein the antibody layer contains antibody print with at least one letter shape. The blood type test card can be widely applied to a main blood type system of ABO, Rh, P, MNSs, Duffy and the like with clinical significance, is easy to popularize and use as well as simple and convenient for operation, leads the blood type result to be directly read and also can avoid theerror caused by human factor.

Description

technical field [0001] The invention relates to a blood type detection card and a production method thereof, belonging to the technical field of blood type detection. Background technique [0002] Blood type testing is mainly based on positive blood type typing. At present, positive blood type typing has always been based on the agglutination reaction between blood type antibodies and corresponding red blood cell antigens. Take ABO blood type as an example: type A red blood cell surface contains A antigen, serum / plasma contains B antibody; B type red blood cell surface contains B antigen, serum / plasma contains A antibody; AB type red blood cell surface contains AB antigen, serum / plasma does not Contains AB antibodies; Type O blood does not contain AB antigens on the surface, but contains AB antibodies in serum / plasma. The agglutination reaction formed by this antigen antibody is interpreted by medical professionals based on blood typing reagents. [0003] The positive bloo...
