Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blood type detection, in particular to an Rh blood type rapid detection reagent card. Background Art
[0002] The Rh blood group system is the most complex of the human red blood cell types, and its importance in clinical blood transfusion is second only to the ABO blood group system. The RH blood group system primarily consists of five antigens: C, c, D, E, and e. Currently, only the D antigen is a mandatory test item before clinical blood transfusion. Most hospitals, especially those at the grassroots level, lack the conditions to test and match the other antigens of the Rh blood group system during blood transfusions, resulting in patients receiving foreign antigens and developing unexpected antibodies. In recent years, cases of unexpected antibody production due to transfusions of blood with mismatched Rh antigens have become common, posing a significant threat to transfusion safety. Currently, the main method for Rh typing is the microcolumn gel method, which provides relatively accurate results but often requires appropriate instruments and equipment, is cumbersome to operate, and requires professionally trained technicians to interpret the results, placing high demands on personnel.
