Description

Technical Field

[0001] This utility model relates to the field of transfusion compatibility testing technology, and in particular to a transfusion compatibility testing quality control kit. Background Technology

[0002] Currently, there are no commercially available internal quality control products for transfusion compatibility testing with SFDA approval numbers in China. Among known foreign products of the same type, only internal quality control products for ABO and RhD blood typing and irregular antibody screening are available, but no internal quality control products for crossmatch testing are available. Only a few transfusion compatibility testing laboratories in China have conducted some internal quality control work.

[0003] Internal quality control items for transfusion compatibility testing include ABO forward and reverse typing, RhD typing, Rh typing, antibody screening, and crossmatching. Existing internal quality control kits for transfusion compatibility testing contain a large number of control tubes and cannot fully cover all quality control items.

[0004] Based on the above-mentioned technical problems, those skilled in the art urgently need to develop a transfusion compatibility testing quality control kit that is simple in structure, requires few sample tubes, is easy to operate, comprehensively covers quality control items, and has sensitive and stable test results.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This invention relates to a transfusion compatibility testing quality control kit, comprising a box body and a lid. The box body has openings on both sides and is foldable. The openings on both sides are opened or closed by the lid. The kit also includes:

[0008] Three fixing holes provided in the box body; and

[0009] The first, second, and third quality control tubes are respectively placed in the three fixing holes, and each of the three quality control tubes contains quality control red blood cells and quality control plasma.

[0010] Furthermore, the quality control red blood cells are derived from healthy blood donors and have a concentration of 15% to 20% in the quality control plasma;

[0011] The quality control plasma includes glucose, phosphate buffer, antibiotics, humanized anti-D monoclonal antibody IgG, mouse anti-A IgM, and anti-B monoclonal antibody IgM.

[0012] The transfusion compatibility testing quality control kit provided by this utility model, as described above, has the following beneficial effects:

[0013] The transfusion compatibility testing quality control kit of this invention has a simple structure, requires few sample tubes, is easy to operate, comprehensively covers quality control items, is applicable to multiple methodologies, and provides sensitive and stable test results. Attached Figure Description

[0014] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in this utility model. For those skilled in the art, other drawings can be obtained based on these drawings.
