Problems solved by technology

[0015] The blood type anti-typing reagent prepared with Alfred's solution can be stored at 4°C for one month. Excluding the transportation and distribution time, it will only be valid for about 2 weeks when it reaches the end user, and the long-distance transportation will not take into account the stability of the cell membrane and cell viability. The impact of the detection cost is very high for many users
[0016] Another example is Japan's MAP liquid, AS-5 liquid, etc., which are not ideal because of the short storage period (only 1 month) and the complexion of red blood cells.

Abstract

A counter typing reagent of ABO blood type is prepared as improving buffer system to change single citrate buffer system to be citrate-phosphate double-buffer system, adding adenine as nutrition composition, applying no any chemical anticorrosive in anticorrosion system and adding EDTA for preventing red blood cell of blood type from hemolysis.

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...
