Rh blood type detecting card

Abstract

The invention provides an Rh blood type detecting card comprising a detecting card with six micro-columns, wherein the six micro-columns are internally and respectively filled with equivalent D-resistant gel, C-resistant gel, c-resistant gel, E-resistant gel, e-resistant gel and blank gel. The Rh blood type detecting card is prepared by using the following method comprising the steps of swelling dextran gels; preparing all antibody diluents; preparing all antibody working solutions; washing the gels; and subpackaging to form the Rh blood type detecting card. According to the Rh blood type detecting card, crosslinked dextran gels with different sizes and sieving ranges are mixed and swelled by using purified water, so that the specificity is effectively ensured, meanwhile, the Rh blood type detecting card has very high sensitivity, and the ion strength of a system is effectively ensured.

Description

technical field

[0001] The invention relates to the medical field, in particular to a Rh blood type detection card. Background technique

[0002] The Rh system is an extremely complex blood group system, second only to the ABO system in importance. Among them, D antigen is the most important antigen in the Rh blood group antigen system. If D antigen exists on the human red blood cell membrane, it is RhD positive, and if D antigen does not exist, it is RhD negative. In addition to the D antigen, the C, c, E, and e antigens are also the main antigens in the Rh system, which have strong clinical significance. In addition, since the vast majority of irregular antibodies belong to the antibodies of the Rh blood group system, after transfusion of blood containing the corresponding antigens, it can cause severe immune hemolytic transfusion reactions, and IgG antibodies of the Rh system have a strong ability to pass through the placenta.
