Abstract

This invention relates to one ABO blood reverse shape agent, which is based on the a's liquid and adopts the improved buffer system, that is from single citrate buffer system into citrate and phosphate double buffer system to better keep the system PH value stable, wherein, the invention adds gland purine as nutrient to make the erythrocyte keep bright color during abundant oxygen process; the anti-erosion system not adopting any chemical antigen to avoid impacting the oxygen content to make the red cell dark; adding EDTA sodium salt to prevent blood-stop cell hemolytic phenomenon.

Description

Technical field: [0001] The invention relates to a detection reagent, in particular to a blood detection reagent, in particular to a reverse typing blood detection reagent for ABO blood type. Background technique: [0002] Red blood cell blood type is the earliest human blood type discovered, and it is a genetic marker of human beings, which is of great significance to anthropology, genetics, blood transfusion, matching, organ transplantation and neonatal immune diseases. Since Landsteinor (1900) discovered the ABO blood type, Hoktoen proposed the importance of blood type identification for blood transfusion therapy as early as 1907, and Ottenberg et al. further proposed the concept of donor-recipient blood cross-mating experiment in 1908, emphasizing the importance of blood type identification for transfusion therapy. The far-reaching significance of clinical blood transfusion. Due to the importance of ABO blood type in blood transfusion, correct identification of ABO bloo...
